General description

L-Ascorbic acid is the most biologically active form of ascorbic acid. It is hydrophilic and an unstable compound. L-Ascorbic acid contains a six-carbon lactone produced by plants and some animal species but not by humans and other primates. Ascorbic acid, also referred to as Vitamin C, is a water-soluble vitamin. Ascorbic acid carries a neutral charge, which gets converted to ascorbate by protonation. Vitamin C is a part of citrus fruits, such as broccoli, strawberries, turnip.

Biochem/physiol Actions

L-Ascorbic acid functions according to its oxido-reduction property. It is a co-factor for hydroxylation. The biochemical actions of L-ascorbic acid is dependent on the activity of monoxygenase. It is involved in carnitine, collagen synthesis and production of neurotransmitters. Vitamin C exhibits anti-oxidant properties. Vitamin C plays a role in providing protection against photoaging and anti-aging effect. Deficiency of vitamin C leads to scurvy, bleeding gums, poor wound healing, anemia and muscle degeneration.
