Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. [6] It also functions as an antioxidant.
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. [1] There is no strong scientific evidence that vitamin C ...
Published in English. 1970. Vitamin C and the Common Cold is a popular book by Linus Pauling, first published in 1970, on vitamin C, its interactions with common cold and the role of vitamin C megadosage in human health. [1] The book promoted the idea that taking large amounts of vitamin C could reduce the duration and severity of the common cold.
Acidity[edit] Ascorbic acid is a furan -based lactone of 2-ketogluconic acid. It contains an adjacent enediol adjacent to the carbonyl. This −C (OH)=C (OH)−C (=O)− structural pattern is characteristic of reductones, and increases the acidity of one of the enol hydroxyl groups.
Alternative medicine. Intravenous Ascorbic Acid or PAA, pharmacologic ascorbic acid [1] (also known as vitamin C or L-ascorbic acid ), is a process that delivers soluble ascorbic acid directly into the bloodstream. It is not approved for use to treat any medical condition.
Sodium ascorbate is one of a number of mineral salts of ascorbic acid (vitamin C). The molecular formula of this chemical compound is C 6 H 7 NaO 6. As the sodium salt of ascorbic acid, it is known as a mineral ascorbate. It has not been demonstrated to be more bioavailable than any other form of vitamin C supplement. [2]
Dehydroascorbic acid ( DHA) is an oxidized form of ascorbic acid (vitamin C). It is actively imported into the endoplasmic reticulum of cells via glucose transporters. [1] It is trapped therein by reduction back to ascorbate by glutathione and other thiols. [2] The (free) chemical radical semidehydroascorbic acid (SDA) also belongs to the group ...
Erythorbic acid ( isoascorbic acid, D-araboascorbic acid) is a stereoisomer of ascorbic acid ( vitamin C ). [1] It is synthesized by a reaction between methyl 2-keto- D -gluconate and sodium methoxide. It can also be synthesized from sucrose or by strains of Penicillium that have been selected for this feature. [2]
