Vitamin C (VC) Content Assay Kit (Copper Ion, Colorimetric Method)

Cat. No.: V1515892

GRADE & PURITY BioReagent

Descripción general

Vitamin C, also known as L-ascorbic acid, is an essential nutrient for higher primates and a few other organisms. In living organisms, it acts as an antioxidant. As an acidic hexose derivative—specifically an enol-form hexonic acid lactone—it protects the body against threats from free radicals and also functions as a coenzyme. It is widely available from various fresh fruits and vegetables. Vitamin C exists in two isomeric forms, L-type and D-type, with only the L-type possessing physiological activity. Both the reduced and oxidized forms exhibit biological activity. The detection principle of this kit is based on the conjugated double bonds in the molecular structure of vitamin C, which result in a maximum absorption peak at 243 nm in acidic solutions. Under neutral or alkaline conditions, the maximum absorption peak shifts to 265 nm. By utilizing copper ions to eliminate background interference, the vitamin C content in samples can be directly measured using a spectrophotometer. This kit is primarily used for the detection of vitamin C (ascorbic acid) in plant tissues. This product is intended for research use only and is not suitable for clinical diagnosis or other purposes.
