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.[1] It is a water-soluble vitamin.[2]

Zastosowanie

L-Ascorbic acid has been used as a standard in high performance liquid chromatography (HPLC) for quantification of L-ascorbic acid.[3]
L-Ascorbic acid may be used as standard in assay for erythrocyte hemolysis mediated by peroxyl free radicals.[4] It may be used for the reduction of graphene oxide sheets.[5]

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.[6] It has mild reductive ability and nontoxic property. It is commonly employed reductant in the laboratory.[5] Colorimetric determination of ascorbic acid in plasma using acid phosphotungstate has been reported.[7]
L-ascorbic acid modified poly(ester urethane)s might facilitate soft tissue regeneration.[8] It also helps in increasing iron absorption by tissues. In addition, it aids in tyrosine metabolism and microsomal drug metabolism.[1]
