Vitamin Analysis
Reactive oxygen species can generate lipid peroxides, which increase susceptibility to arteriosclerosis, and can lead to such conditions cancer, aging, and a decrease in immune function. The human body through the production of enzymes possesses the intrinsic capacity to suppress reactive oxygen species, but the amount of enzymes produced in the body decreases with age. Vitamins with antioxidant properties that suppress the action of reactive oxygen species are called antioxidant vitamins. Antioxidant vitamins are being recognized as one of the antioxidants which suppress the action of reactive oxygen species that cannot be processed by enzymes.
Antioxidant vitamins include vitamin A, vitamin C, and vitamin E.
Vitamin A is abundantly contained in foods as β-carotene (a class of carotenoids). β-Carotene has a function to suppress the generation of reactive oxygen species and remove it.
Vitamin E has a function to suppress the production of lipid peroxides in cells in addition to antioxidant effects.
Vitamin C also has a function to suppress the production of lipid peroxides.
In addition to the above, some of the compounds called vitamin-like active substances,*1 which are not strictly classified as vitamins, have antioxidant effects, such as coenzyme Q10.*2
Vitamins are analyzed by high-performance liquid chromatography, microbiological assay, etc.
Fujifilm Wako supplies a wide range of reagent groups related to vitamin analysis that can be used for these analyses.
