M.F.：C6H8O6
Specification：40-80mesh, 100,200,320mesh.
Appearance：White crystalline powder
White crystalline powder. Ascorbic acid is the enolic form of 3-oxo-L- gulofuranolac-tone. It can be prepared by synthesis from glucose, or extracted from plant sources such as rose hips, blackcurrants or citrus fruits. It is easily oxidized in air. It is essential for the formation of collagen and intercellular material, bone and teeth and for healing of wounds. It helps maintain elasticity of the skin, aids the absorption of iron and improve resistance to infection. The lack of VC will cause scurvy.
