Opis

Opis ogólny

Ascorbic Acid, also known as Vitamin C, is a six-carbon lactone produced by plants and some animal species but not by humans and other primates. It is a water-soluble vitamin.

Zastosowanie

L-Ascorbic acid has been used as a standard in high performance liquid chromatography (HPLC) for quantification of L-ascorbic acid.

L-Ascorbic acid may be used as standard in assay for erythrocyte hemolysis mediated by peroxyl free radicals. It may be used for the reduction of graphene oxide sheets.

Działania biochem./fizjol.

L-Ascorbic acid is an anti-oxidant. L-Ascorbic acid (vitamin C) is important for many enzymatic reactions for maintaining prosthetic metal ions in their reduced forms (for example, Fe²⁺, Cu⁺). It protects tissues from oxidative damage by scavenging free radicals. It has mild reductive ability and nontoxic property. It is commonly employed reductant in the laboratory. Colorimetric determination of ascorbic acid in plasma using acid phosphotungstate has been reported.

L-ascorbic acid modified poly(ester urethane)s might facilitate soft tissue regeneration. It also helps in increasing iron absorption by tissues. In addition, it aids in tyrosine metabolism and microsomal drug metabolism.
