Product Description

Ascorbic acid is a naturally occurring organic compound with antioxidant properties. It is a white solid, but impure samples can appear yellowish. It dissolves well in water to give mildly acidic solutions. Because it is derived from glucose, many animals are able to produce it, but humans require it as part of their nutrition. Other vertebrates which lack the ability to produce ascorbic acid include other primates, guinea pigs, teleost fishes, bats, and some birds, all of which require it as a dietary micronutrient (that is, in vitamin form).
There exists a D-ascorbic acid, which does not occur in nature. It may be synthesized artificially. It has identical antioxidant properties to L-ascorbic acid yet has far less vitamin C activity (although not quite zero).

Characteristics
colorless crystals or a white or almost white, crystalline powder which discolors on exposure to air and moisture; Odorless or almost odorless and tasted sour; Easily soluble in water and a few partial soluble in ethanol; Insoluble in ether and chloroform.

Function
It applies mainly to production of various medicines as clinically important material for supplementary cure practice in different sectors. Being food additives, it acts as superior and reliable agent in nutrition, antiseptic and flour processing aspects. It also helps enhance the immune system of animals as being served in feed additives.
