Retinyl acetate (Vitamin A Acetate) is a yellow prismatic crystal, a lipid compound, and its chemical stability is better than vitamin A. This product or its palmitate is often used clinically dissolved in vegetable oil, and is hydrolyzed by enzymes in the body to obtain vitamin A. The vitamin A recorded in the Chinese Pharmacopoeia is actually vitamin A acetate.
There are two types of vitamin A alcohol: vitamin A1 alcohol, which is retinol, and vitamin A2 alcohol, which is dehydroretinol. Vitamin A alcohol usually refers to vitamin A1 alcohol. The biological potency of vitamin A2 alcohol is 30-40% of that of vitamin A1 alcohol. Its structure is similar to vitamin A1 alcohol, except that it has one more double bond at the C-3 and C-4 positions of the cyclohexene ring.
