APPLICATIONS
Ascorbic acid (also called vitamin C ) is a carbohydrate-like substance involved in the metabolic functions including synthesis of collagen, maintenance of the structural strength of the blood vessels, metabolism of certain amino acids, and the synthesis or release of hormones in the adrenal glands. It occurs as a white or slightly yellow crystal or powder with a slight acidic taste. Traditional synthesis of ascorbic acid is through the Reichstein process which requires bioconversion of sorbitol followed by a seven-step chemical process. Newly developted fermentation technology is used to reduce production costs of the key ascorbic intermediate, ketogulonic acid. Vitamin C has a very simple structure. Chemically, it is ketothreohexuronic acid. It is an antiscorbutic product. On exposure to air and light it gradually darkens. Ascorbic Acid is freely soluble in water; sparingly soluble in alcohol; insoluble in chloroform, ether, and benzene.
Vitamin C is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Ascorbic acid is easily oxidized. L form ascorbic acid (Vitamin C) biologically functions as a reductant and a coenzyme in several metabolic pathways. Ascorbic acid and its sodium, potassium, and calcium salts, used as food preservative, are water soluble. Ascorbates, fat-soluble esters of ascorbic acid, can be used as a food antioxidant. Ascorbic acid can be easily destroyed under the exposure to oxygen, metals, light and heat. Ethylated ascorbic acid at position 3 is a stable Vitamin C product with same effect.
