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.
