描述:

Application

For use in cell culture applications as an antioxidant and to regenerate tocopherol.

L-ascorbic acid has been used:

• in an osteogenic supplement for the growth of cells

• as a component in the differentiation media

• in WS-MSCs (Werner syndrome-mesenchymal stem cells) to study rescuing properties of ascorbic acid on aging defects

 

Biochem/physiol Actions

L-ascorbic acid mainly exhibits antioxidant properties. It protects plants from oxidative stress and mammals from diseases associated with oxidative stress. L-ascorbic acid mainly protects from hydroxyl radicals, superoxide and singlet oxygen. In addition, it also reduces the membrane-linked antioxidant α-tocopherol (oxidised form). L-Ascorbic acid enhances endothelium-dependent vasodilation in various disorders, including diabetes, coronary artery disease, hypertension and chronic heart failure.

 

General description

L-ascorbic acid is an unsaturated γ-lactone ring containing an enediol configuration (–COH=COH) attached with a carbonyl group.
