Who discovered with vitamin C?
Abstract – Albert Szent-Györgyi, a Hungarian biochemist, discovered vitamin C and rutin (vitamin P). The role of these vitamins in the body and their application to dermatology is vast. For the discovery of vitamin C and the description of oxidation, Albert Szent-Györgyi received a Nobel Prize in medicine in 1937.
- He discovered the role of adenosine triphosphate, actin-myosin, and many phases of the Krebs cycle, and also initiated studies on the influence of free radicals in the formation of tumors.
- Between 1918 and 1946, he worked in many European research centers and between 1947 and 1986, in the United States.
His achievements were made possible due to his perseverance, which allowed him to overcome many maelstroms that plagued his scientific career.

When did vitamin C discovered?
Abstract – The term ‘scurvy’ for the disease resulting from prolonged vitamin C deficiency had origins in ‘scorbutus’ (Latin), ‘scorbut’ (French), and ‘Skorbut’ (German). Scurvy was a common problem in the world’s navies and is estimated to have affected 2 million sailors.
- In 1747, James Lind conducted a trial of six different treatments for 12 sailors with scurvy: only oranges and lemons were effective in treating scurvy.
- Scurvy also occurred on land, as many cases occurred with the ‘great potato famine’ in Ireland in 1845.
- Many animals, unlike humans, can synthesize their own vitamin C.
Axel Holst and Theodor Frölich fortuitously produced scurvy in the guinea pig, which like humans requires vitamin C in the diet. In 1928, Albert Szent-Györgyi isolated a substance from adrenal glands that he called ‘hexuronic acid’. Four years later, Charles Glen King isolated vitamin C in his laboratory and concluded that it was the same as ‘hexuronic acid’.

Who Discovered of vitamin?
Abstract – The discovery of the vitamins was a major scientific achievement in our understanding of health and disease. In 1912, Casimir Funk originally coined the term “vitamine”. The major period of discovery began in the early nineteenth century and ended at the mid-twentieth century.
The puzzle of each vitamin was solved through the work and contributions of epidemiologists, physicians, physiologists, and chemists. Rather than a mythical story of crowning scientific breakthroughs, the reality was a slow, stepwise progress that included setbacks, contradictions, refutations, and some chicanery.
Research on the vitamins that are related to major deficiency syndromes began when the germ theory of disease was dominant and dogma held that only four nutritional factors were essential: proteins, carbohydrates, fats, and minerals. Clinicians soon recognized scurvy, beriberi, rickets, pellagra, and xerophthalmia as specific vitamin deficiencies, rather than diseases due to infections or toxins.
Experimental physiology with animal models played a fundamental role in nutrition research and greatly shortened the period of human suffering from vitamin deficiencies. Ultimately it was the chemists who isolated the various vitamins, deduced their chemical structure, and developed methods for synthesis of vitamins.
Our understanding of the vitamins continues to evolve from the initial period of discovery.

Who is Linus Pauling vitamin C?
In 1970, Dr. Linus Pauling published Vitamin C and the Common Cold, a book that revolutionized the way the world viewed vitamin C and infectious disease. Dr. Pauling believed that increasing the daily dose of vitamin C could help the body mount a strong immune response when confronted with a respiratory infection.
- Many people worldwide have reported better health after taking large amounts of vitamin C.
- To date, clinical trials have shown that vitamin C supplements can shorten the duration of the common cold.
- However, there are no data to suggest that vitamin C supplements can stop respiratory infections in the general population.* The LPI continues to advocate for rigorous research on both oral and IV vitamin C for treating both inflammation and infection.
Yet, the facts are that there have been few rigorous studies on vitamin C and respiratory infections. Clinical trials with IV vitamin C and coronavirus-related pneumonia are currently underway in China, These trials are of great interest to the LPI, and we will monitor them closely.
Meanwhile, the LPI recommends taking these steps to support a healthy immune system: Eat a healthy diet and ensure that you meet the recommended intakes of all micronutrients, especially vitamins A, C, D, E, as well as zinc. You can find recommended intakes for essential nutrients in our Micronutrients for Health handout.
More information about the immune system and micronutrients is available in the Micronutrient Information Center article, Immunity in Brief, Oregon State University has established a COVID-19 website to provide detailed and updated information; links to OSU, local, state and federal resources; and some frequently asked questions.

Who discovered vitamin B and C?
Specific Vitamin Discoveries – Throughout the 20 th century, scientists were able to isolate and identify the various vitamins found in food. Here is a short history of some of the more popular vitamins.
Vitamin A (a group of fat-soluble retinoids, including retinol, retinal, and retinyl esters ) — Elmer V. McCollum and Marguerite Davis discovered Vitamin A around 1912 to 1914. In 1913, Yale researchers Thomas Osborne and Lafayette Mendel discovered that butter contained a fat-soluble nutrient soon known as vitamin A. Vitamin A was first synthesized in 1947. Vitamin B (known as biotin, a water-soluble vitamin that helps the body convert carbohydrates, fats, and proteins into energy) —Elmer V. McCollum also discovered Vitamin B sometime around 1915–1916. Vitamin B1 (also known as thiamine, a water-soluble B vitamin that plays a critical role in energy metabolism) —Casimir Funk discovered Vitamin B1 (thiamine) in 1912. Vitamin B2 (also known as riboflavin, an important role in energy production, cellular function, and metabolism) — D.T. Smith, E.G. Hendrick discovered B2 in 1926. Max Tishler invented methods for synthesizing the essential vitamin B2. Niacin —American Conrad Elvehjem discovered Niacin in 1937. Folic acid — Lucy Wills discovered Folic acid in 1933. Vitamin B6 (six compounds which are extremely versatile and primarily work on protein metabolism) — Paul Gyorgy discovered Vitamin B6 in 1934. Vitamin C (ascorbic acid, required for the biosynthesis of collagen) —In 1747, Scottish naval surgeon James Lind discovered that a nutrient in citrus foods prevented scurvy. It was re-discovered and identified by Norwegian researchers A. Hoist and T. Froelich in 1912. In 1935, Vitamin C became the first vitamin to be artificially synthesized. The process was invented by Dr. Tadeusz Reichstein of the Swiss Institute of Technology in Zurich. Vitamin D (promotes calcium absorption in the gut and enable bone mineralization) — In 1922, Edward Mellanby discovered Vitamin D while researching a disease called rickets. Vitamin E (important anti-oxidant) — In 1922, University of California researchers Herbert Evans and Katherine Bishop discovered Vitamin E in green leafy vegetables.
How was vitamin C named?
What is vitamin C? How does it function biochemically? Why can’t humans synthesize it? Also known as ascorbic acid, vitamin C is a small carbohydrate molecule first identified in the 1920s by Albert von Szent Györgyi, who discovered that it was able to prevent and cure scurvy.
Scurvy is a pathological life-threatening condition suffered by people who do not have access to fruits or vegetables for long periods of time. A decade earlier, Kazimierz Funk had prepared a list of nutritional factors, called vitamins, whose deficiencies cause severe diseases in humans. In his list, Funk used the letter “C” to designate a factor still unidentified, but known to prevent scurvy.
Later on, Szent Györgyi and Haworth chemically identified “C” as ascorbic acid, and named it so because ascorbic means “anti-scurvy.” Over the next century, what we now know as vitamin C became one of the most popular drugs in human history. Why is this molecule so well-known? Apart from its deficiency causing scurvy in humans, vitamin C is also vitally important to other species,

Where is vitamin C found?
Overview – Vitamin C (ascorbic acid) is a nutrient your body needs to form blood vessels, cartilage, muscle and collagen in bones. Vitamin C is also vital to your body’s healing process. Vitamin C is an antioxidant that helps protect your cells against the effects of free radicals — molecules produced when your body breaks down food or is exposed to tobacco smoke and radiation from the sun, X-rays or other sources.
- Free radicals might play a role in heart disease, cancer and other diseases.
- Vitamin C also helps your body absorb and store iron.
- Because your body doesn’t produce vitamin C, you need to get it from your diet.
- Vitamin C is found in citrus fruits, berries, potatoes, tomatoes, peppers, cabbage, Brussels sprouts, broccoli and spinach.
Vitamin C is also available as an oral supplement, typically in the form of capsules and chewable tablets. Most people get enough vitamin C from a healthy diet. Vitamin C deficiency is more likely in people who:
- Smoke or are exposed to secondhand smoking
- Have certain gastrointestinal conditions or certain types of cancer
- Have a limited diet that doesn’t regularly include fruits and vegetables
Severe vitamin C deficiency can lead to a disease called scurvy, which causes anemia, bleeding gums, bruising and poor wound healing. If you take vitamin C for its antioxidant properties, keep in mind that the supplement might not offer the same benefits as naturally occurring antioxidants in food.

What was Pauling’s discovery?
Linus Pauling: A Lifetime of Science The self-taught chemist. Linus Pauling’s lifelong fascination with chemistry was ignited during childhood by a friend’s chemistry set. He was born on February 28, 1901, in Portland, Oregon, to a family that lacked the resources to buy him a chemistry set, so Pauling created his own using chemicals he found in an abandoned iron smelter.
He quickly taught himself more about chemistry than he could learn in his local high school. The education. Pauling enrolled in college at age 16, and he was teaching the course he had taken the year before by age 18. He was a charismatic public speaker who was able to make the most advanced chemistry concepts interesting, even to those who knew nothing about chemistry.
His students loved him, especially a young woman named Ava Helen, who later became his wife and the mother of his four children. Pauling finished his education at the California Institute of Technology, where he would spend most of his career researching and teaching.
The work. The genius of Pauling’s work rests not in a single discovery; it lies in its scope. Indeed, he won the Nobel Prize in chemistry for his entire body of work, not just a single accomplishment. Pauling is probably best known for working out the nature of the chemical bond, yet he also discovered (among many other accomplishments) the cause of sickle cell anemia, developed an accurate oxygen meter for submarines, helped create synthetic plasma, and determined the structure of proteins.
The activism. During WWII, Pauling’s laser-like focus on his work shifted for the first time since his childhood. He took a public stance against war and the use of nuclear weapons while advocating for international diplomacy through the United Nations.
He was later awarded the Nobel Peace Prize for his crusade against nuclear-weapons testing. In his later years, Pauling became a champion for Vitamin C. He believed that taking very high doses of this vitamin would ward off infection, and perhaps even prevent or treat cancer. The price. In the early 1950s, many scientists were racing to discover the structure of DNA.
Pauling proposed a triple helix structure with the bases on the outside, but James Watson and Francis Crick ultimately disproved his idea with their famous double helix model. They had succeeded largely because they had access to X-ray crystallography data from scientists at King’s College in London.
- If Pauling had been able to collaborate with these scientists, he may have been able to correct the errors in his model and claim the prize.
- However, his political activism brought on suspicion that he was a communist.
- Due to irrational distrust of liberalism among US political leaders at the time, he was blacklisted, and was not allowed to leave the country.
His belief in pacifism may have cost him what could have been the crowning achievement of his career. Always a scientist. Pauling spent his last years directing research at the Linus Pauling Institute and writing about subjects that interested him, such as the structure of atomic nuclei.

Who discovered vitamin C in green tea?
Google honours Japanese scientist who discovered components in Green Tea | | Google Honours Japanese Scientist Who Discovered Components In Green Tea Tsujimura began researching the biochemistry of green tea alongside Dr Umetaro Suzuki, a doctor of agriculture who discovered vitamin B1 Updated On – 03:03 PM, Fri – 17 September 21 
Hyderabad: Google Doodle on Friday honoured Michiyo Tsujimura, a Japanese chemist who did in-depth research on green tea, on the occasion of her 133rd birth anniversary. She was known for her in-depth study on the chemical components of green tea and its nutritional benefits.
- Interestingly, a variety of research components, such as a tea shrub, a cup of green tea and its vapour, a pen, a notepad, and a flask were used to form the letters of ‘Google’.
- Michiyo Tsujimura was born on September 17, 1888, in Okegawa, Japan.
- While in school, Tsujimura was inspired to pursue a career in scientific research.
With a determined goal, she became Japan’s first woman doctor of agriculture in 1932. Tsujimura began researching the biochemistry of green tea alongside Dr Umetaro Suzuki, a doctor of agriculture who discovered vitamin B1. While working on the research, Michiyo Tsujimura and her colleague discovered green tea to contain significant amounts of vitamin C.
It was also one of the first components discovered. As Tsujimura further explored green tea, she was able to isolate more of its chemical composition like catechin – a bitter ingredient of tea and tannin – an even bitter compound. In 1932, Tsujimura published her doctoral thesis titled ‘On the Chemical Components of Green Tea’ that included these findings and more.
She also went on to patent a method of extracting crystallised Vitamin C from plants in 1935. Upon completing her research career, Dr Tsujimura also made history as an educator when she became the first Dean of the Faculty of Home Economics at Tokyo Women’s Higher Normal School in 1950.

Who discovered vitamin C 1912?
Albert Szent-Györgyi—The Scientist Who Discovered Vitamin C In the 1920s and 1930s, Dr. Albert Szent-Györgyi, a Hungarian professor of medicinal chemistry, made some very important discoveries that help us to understand basic nutrition. While conducting a series of early experiments on citrus plants, he found that plant browning could be caused by peroxidase, a plant enzyme that is active during oxidation.
By adding citrus juice to peroxidase, the browning process could be stopped. In his experiments he isolated a substance he called, hexuronic acid that he thought was active within citrus juice. This was one of the first steps in the discovery of what we know today as vitamin C. Szent-Györgyi, also conducted experiments on guinea pigs, which are similar to humans, in that they have to consume hexuronic acid to remain healthy.
He decided to rename hexuronic acid to ascorbic acid or vitamin C, reflecting its anti-scorbutic (scurvy fighting) properties. It took many years to find a way to produce large amounts of ascorbic acid from natural sources. It was by chance he found the answer in his dinner! The story goes that he did not want to eat the paprika in his dinner, so he took it to his laboratory, where he found it to contain large amounts of vitamin C.
- Without his discovery we would not know that vitamin C is important for proper functioning of our immune system.
- By eating our daily dose of fruits and vegetables, which contain vitamin C, we improve the repair and growth of tissue and many more factors that keep us healthy.
- Szent-Györgyi was awarded the Nobel Prize in Physiology or Medicine in 1937 for his discovery of vitamin C.
He is also known for his later contribution to what we know as the Citric Acid (Krebs) cycle. “Discovery consists of seeing what everybody has seen and thinking what nobody has thought.” -Albert Szent-Györgyi in Irving Good, The Scientist Speculates (1962).
- ‘s discovery begins with a disease called,
- Prolonged vitamin C deficiency leads to scurvy and, if left untreated, can be fatal.
- Symptoms of scurvy include feeling tired, bleeding gums or skin that bruises.
- As these symptoms worsen, patients may develop open sores, lose teeth and can even die.
- Other symptoms include impaired wound healing, muscle weakness and hemorrhages (an escape of blood from a ruptured blood vessel).
Sounds pretty nasty, right? People have complained about this disease since ancient times. Some records of scurvy have been around since 1500 BC Egypt, Scurvy was a big problem for sailors in the eighteenth century. They ate a lot of dried meats and grains and did not include fruits and vegetables in their diet.
- This was because these foods would not remain fresh on long sea journeys.
- In 1757, James Lind, a Scottish doctor, discovered that fresh citrus fruits could prevent scurvy.
- It was then mandatory for sailors in the British navy to consume citrus fruits and lemon juice,
- In 1907, other scientists like Axel Holst and Alfred Frohlich proposed that a special substance existed in these fruits while Casimir Funk coined the term Vitamin C in 1912,
He developed the concept of, and showed that these “vital” substances were needed to keep people healthy and free of disease. His terminology as well as the discovery made by Holst and Frohlich led to the substance being called “water-soluble C” which then eventually became Vitamin C.
