Deficiency of vitamin C causes scurvy, formerly a major disease of sailors in long sea voyages. It is used as a food additive and a dietary supplement for its antioxidant properties. The "d" form (erythorbic acid) can be made by chemical synthesis, but has no significant biological role.
Vitamin C supplements among other dietary supplements at a US drug store. Vitamin C has a definitive role in treating scurvy, which is a disease caused by vitamin C deficiency. Beyond that, a role for vitamin C as prevention or treatment for various diseases is disputed, with reviews often reporting conflicting results.
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 ascorbic acid by glutathione and other thiols. [2]
Mayo Clinic also notes that for most people, a healthy diet alone can supply enough vitamin C. “Aim to get at least 90 mg per day of vitamin C from food,” Blautner recommends. She suggests the ...
Vitamin B 12 ; Vitamin C (ascorbic acid and ascorbates) Vitamin D (calciferols) Vitamin E (tocopherols and tocotrienols) Vitamin K (phylloquinones, menaquinones, and menadiones) Some sources include a fourteenth, choline. [6] Vitamins have diverse biochemical functions. Vitamin A acts as a regulator of cell and tissue growth and differentiation.
Ascorbic acid or vitamin C, an oxidation-reduction catalyst found in both animals and plants, [82] can reduce, and thereby neutralize, reactive oxygen species such as hydrogen peroxide. [ 82 ] [ 83 ] In addition to its direct antioxidant effects, ascorbic acid is also a substrate for the redox enzyme ascorbate peroxidase , a function that is ...
Vitamin C is vital for collagen synthesis, while Vitamin E improves its production. HCR-FISH visualization of collagen expression in the Iberian ribbed newt. Depending on the degree of mineralization, collagen tissues may be rigid (bone) or compliant (tendon) or have a gradient from rigid to compliant (cartilage).
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]
