Description
Ascorbic acid — organic compound, related to glucose, is one of the main substances in a human diet which is necessary for normal functioning of a connecting and bone tissue.
Carries out biological functions of a reducer and coenzyme of some metabolic processes, is antioxidant. Only one of isomers — L-ascorbic acid which is called vitamin C is biologically active. In the nature ascorbic acid contains in many fruit and vegetables. Gipovitaminoz of ascorbic acid leads to a scurvy.
On physical properties ascorbic acid represents white crystal powder of sour taste. Let's easily dissolve in water, we will dissolve in alcohol. Because of existence of two asymmetric atoms there are four diastereomer of ascorbic acid. Two hiralna forms which are conditionally called by L-and D-concerning atom of carbon in a furanovy ring, and from - a form are D-isomer on atom of carbon in a lateral ethyl chain. L-isoascorbic, or eritorbovy, acid is used as a food additive of E315.
Ascorbic acid and its sodium (a sodium ascorbate), calcic and potash salts are applied in the food industry in quality antioksidantove300 — E305 preventing oxidation of a product.
