Irwin Stone
Irwin Stone (1907–1984) was an American biochemist, chemical engineer, and writer. He was the first to use ascorbic acid in the food processing industry as a preservative, and originated and published the hypothesis that humans require much larger amounts of Vitamin C for optimal health than is necessary to prevent scurvy. Food preservative work In 1934, Stone, while director of the enzyme and fermentation research laboratory for the Wallerstein Company, worked on the antioxidant properties of ascorbate (also known as Vitamin C), which had then recently been described by Albert Szent-Györgyi only two years earlier. He was awarded 26 patents in industrial chemistry, mainly related to fermentation science, pharmaceutical techniques, and nutrient cultivation.Nutrition Todav. 20 (January/February 1985)p. 30. He discovered he could use ascorbate to keep foodstuffs fresh for longer, limiting the effects of exposure to air and oxidation. Stone obtained the first patents on an indu ...

Biochemist
Biochemists are scientists who are trained in biochemistry. They study chemical processes and chemical transformations in living organisms. Biochemists study DNA, proteins and Cell (biology), cell parts. The word "biochemist" is a portmanteau of "biological chemist." Biochemists also research how certain chemical reactions happen in cells and Tissue (biology), tissues and observe and record the effects of Product (chemistry), products in food additives and Medication, medicines. Biochemist researchers focus on playing and constructing research experiments, mainly for developing new products, updating existing products and analyzing said products. It is also the responsibility of a biochemist to present their research findings and create Grant writing, grant proposals to obtain Funding of science, funds for future research. Biochemists study aspects of the immune system, the expressions of genes, isolating, analyzing, and synthesizing different products, mutations that lead to ca ...

Linus Pauling
Linus Carl Pauling ( ; February 28, 1901August 19, 1994) was an American chemist and peace activist. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics. ''New Scientist'' called him one of the 20 greatest scientists of all time. For his scientific work, Pauling was awarded the Nobel Prize in Chemistry in 1954. For his peace activism, he was awarded the Nobel Peace Prize in 1962. He is one of five people to have Nobel Prize#Multiple laureates, won more than one Nobel Prize. Of these, he is the only person to have been awarded two unshared Nobel Prizes, and one of two people to be awarded Nobel Prizes in different fields, the other being Marie Curie. Pauling was one of the founders of the fields of quantum chemistry and molecular biology. His contributions to the theory of the chemical bond include the concept of orbital hybridisation and the first accurate scale of electronegativity, electronegativities of the elements. Pauling also wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Archie Kalokerinos
Archivides "Archie" Kalokerinos (28 September 1927 – 1 March 2012) was an Australian physician and anti-vaccination advocate. He advocated alternative medicine, including orthomolecular medicine and a form of megavitamin therapy in which high doses of vitamin C are used. He became notable for treating indigenous Australians with a ”counter intuitive” therapy: high intravenous doses of vitamin C, a treatment generally used for patients with severe or subclinical scurvy (not treatable with daily oral intake), but criticized for not being supported by evidence-based medicine, although it brought the infant mortality rate there down to zero. Early life Archivides Kalokerinos was born in Glen Innes, Australia, on 28 September 1927. He earned his MB BS degree from Sydney University in 1951 and then spent six years in England. He held the position of medical superintendent at a hospital in Collarenebri, New South Wales. Anti-vaccination activism Kalokerinos was affiliated wi ...

Orthomolecular Medicine
Orthomolecular medicine is a form of alternative medicine that claims to maintain human health through nutritional Dietary supplement, supplementation. It is rejected by evidence-based medicine. The concept builds on the idea of an optimal nutritional environment in the body and suggests that diseases reflect deficiencies in this environment. Treatment for disease, according to this view, involves attempts to correct "imbalances or deficiencies based on individual biochemistry" by use of substances such as vitamins, Mineral (nutrient), minerals, amino acids, trace elements and fatty acids. The notions behind orthomolecular medicine are not supported by sound evidence-based medicine, medical evidence, and the therapy is not effective for chronic disease prevention; even the validity of calling the orthomolecular approach a form of medicine has been questioned since the 1970s. The approach is sometimes referred to as megavitamin therapy, because its practice evolved out of, and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitamin C Megadosage
Vitamin C megadosage is a term describing the consumption or injection of vitamin C (ascorbic acid) in doses well beyond the current United States Recommended Dietary Allowance of 90 milligrams per day, and often well beyond the tolerable upper intake level of 2,000 milligrams per day. There is no strong scientific evidence that vitamin C megadosage helps to cure or prevent cancer, the common cold, or some other medical conditions. Historical advocates of vitamin C megadosage include Linus Pauling, who won the Nobel Prize in Chemistry in 1954. Pauling argued that because humans and other primates lack a functional form of L-gulonolactone oxidase, an enzyme required to make vitamin C that is functional in almost all other mammals, plants, insects, and other life forms, humans have developed a number of adaptations to cope with the relative deficiency. These adaptations, he argued, ultimately shortened lifespan but could be reversed or mitigated by supplementing humans with t ...

Megavitamin Therapy
Megavitamin therapy is the use of large doses of vitamins, often many times greater than the recommended dietary allowance (RDA) in the attempt to prevent or treat diseases. Megavitamin therapy is typically used in alternative medicine by practitioners who call their approach orthomolecular medicine. Vitamins are useful in preventing and treating illnesses specifically associated with dietary vitamin shortfalls, but the conclusions of medical research are that the broad claims of disease treatment by advocates of megavitamin therapy are unsubstantiated by the available evidence. It is generally accepted that doses of any vitamin greatly in excess of nutritional requirements will result either in toxicity (vitamins A and D) or in the excess simply being metabolised; thus evidence in favour of vitamin supplementation supports only doses in the normal range. Critics have described some aspects of orthomolecular medicine as food faddism or even quackery. A short summary is ithe jour ...

Vitamin
Vitamins are Organic compound, organic molecules (or a set of closely related molecules called vitamer, vitamers) that are essential to an organism in small quantities for proper metabolism, metabolic function. Nutrient#Essential nutrients, Essential nutrients cannot be biosynthesis, synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through the Diet (nutrition), diet. For example, vitamin C can be synthesized by some species but not by others; it is not considered a vitamin in the first instance but is in the second. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. The term ''vitamin'' does not include the three other groups of essential nutrients: mineral (nutrient), minerals, essential fatty acids, and essential amino acids. Major health organizations list thirteen vitamins: * Vitamin A (all-' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
