Vitamin A occurs in three forms: retinol, retinal, and retinoic acid. Retinol is the alcohol form of vitamin A. Replacement of the alcohol group (-OH) by an aldehyde group (-CHO) yields retinal, and replacement by an acid group (-COOH) gives retinoic acid. Vitamin A products for feed use include the acetate, propionate and palmitate esters. Vitamin A alcohol (retinol) is a nearly colorless, fat-soluble, long-chain, unsaturated compound with five bonds (Illus. 2-1). Since it contains double bonds, vitamin A can exist in different isomeric forms. Vitamin A and its precursors, carotenoids, are rapidly destroyed by oxygen, heat, light and acids.
