Vitamin Profiling

Vitamin A (retinol) is essential for the formation of rhodopsin, for bone metabolism, and for the synthesis of steroid hormones. Deficiency of vitamin A leads to night blindness, dry skin, and loss of hair. Vitamin E (α-tocopherol) is a potent antioxidant that protects LDL cholesterol and cellular membranes from lipid peroxidation, which mainly occurs as a result of increased oxidative stress in the organism.

Vitamin C (ascorbic acid) is a water-soluble vitamin that is an essential cofactor for the human body, for instance in the catabolism of tyrosine and the synthesis of catecholamines. Regular consumption of fruit and vegetables is usually sufficient to cover the body’s vitamin C needs.

β-Carotene (Provitamin A) is a precursor form of vitamin A, and is an essential nutrient for the human diet. β-carotene is a herbal dye used as a colouring in the food industry and in vitamin products. In humans, all-trans-β-carotene is functionally and quantitatively the most important of about 20 carotenoids present in the blood plasma. This assay assures reliable separation of α-carotene, cis-β-carotene and all-trans-β-carotene as well as the carotenoids cryptoxanthin and lycopene.
