Description
- General description: 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]
- Application: L-Ascorbic acid has been used as a standard in high performance liquid chromatography (HPLC) for quantification of L-ascorbic acid.[3]
- Biochem/physiol Actions: 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]
- Caution: May darken in storage.
