Vitamin A and E are fat soluble vitamins. Both are stored in the body, thus overdosing is possible. Vitamin A plays an important role in the visual process. It is mainly taken up as pre-vitamin A by nutrition. In the liver it is processed to vitamin A. Retinal is involved in the visual process as prosthetic group of the rhodopsin molecule. Beside this, vitamin A (Retinol) is important for the growth of children and the growth of skin and mucous membranes. As an antioxidant, retinol protects the body against free radicals and reactive oxygen species. Overdosing leads to headache, vertigo, sickness and vomit. Disturbance of the nervous system, skin disease and loss of hair have also been reported.
Vitamin E protects the fatty acids against oxidation. It captures free radicals and reactive oxygen species. A lack of vitamin E is recognized in lipid metabolism disorders, liver disease and in early born children. It leads to muscle dystrophia, anemia and disturbances in the nervous system.
The Eagle Biosciences Vitamin A & Vitamin E HPLC Assay kit makes it possible to determine both vitamins in an easy, fast and precise method. The Eagle Biosciences Vitamin A & Vitamin E HPLC Assay kit includes all reagents ready to use for preparation and separation of the samples with exception of the columns (IC1600rp) and the controls (IC1600ko). Both can be supplied by Eagle Biosciences. Beside the complete test kits it is possible to order all components separately. Please request our single component price list.
