詳細

詳細

Vitamin A is also known as retinol. Retinaldehyde, retinoic acid and retinyl esters are the derivatives of retinol. Retinol consists of a 20-carbon molecule. It also contains a cyclohexanyl ring with a side chain of four double bonds and an alcohol end group. Vitamin A is naturally present in the body as retinyl ester and β-carotene. Retinyl acetate, retinyl propionate and retinyl palmitate are analogs of retinol.

生物化学的／生理学的作用

Retinyl esters are stored in the liver and get converted to retinol before absorption by the intestine. Retinal plays a role in eye vision as it is a part of rhodopsin. Retinol binds to the retinol binding proteins in the plasma. Retinyl acetate has applications in cosmetology.
