Abstract:
A high molecular weight (Sephadex G-15 void volume), water-soluble, fluorescent material that was found to increase significantly in the mouse liver in response to vitamin E deficiency was separated into six proteins by high performance liquid chromatography (HPLC) using a TSK G2000 SW column. One of these proteins increased significantly in concentration due to vitamin E deficiency and had a molecular weight of 20,000 daltons. This protein was found to contain malondialdehyde, an end product of lipid peroxidation, attached to it presumably in a Schiff-base type structure with amino groups. This appears to be the first report in the literature of direct evidence that malondialdehyde is attached to protein in vivo.

Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
