It is a conjugate acid of a L-ascorbate. It is an enantiomer of a D-ascorbic acid. A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant. Ascorbic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Ascorbic acid is a Vitamin C. Ascorbic Acid is a natural product found in Populus tremula, Rosa platyacantha, and other organisms with data available. Ascorbic Acid is a natural water-soluble vitamin (Vitamin C). Ascorbic acid is a potent reducing and antioxidant agent that functions in fighting bacterial infections, in detoxifying reactions, and in the formation of collagen in fibrous tissue, teeth, bones, connective tissue, skin, and capillaries. Found in citrus and other fruits, and in vegetables, vitamin C cannot be produced or stored by humans and must be obtained in the diet. (NCI04) A six carbon compound related to glucose.

Sodium erythorbate
Antioxidant, antimicrobial agent, appearance control agent, curing accelerator for baked goods, meat and cured meat products. Restricted use in Japan. Sodium erythorbate (C6H7NaO6) is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. When used in processed meat such as hot dogs and beef sticks, it reduces the rate at which nitrate reduces to nitric oxide, thus retaining the pink coloring. As an antioxidant structurally related to vitamin C, it helps improve flavor stability and prevents the formation of carcinogenic nitrosamines. When used as a food additive, its E number is E316.
