Biochem/physiol Actions
Retinal, retinol and retinoic acid are the aldehyde, alcohol and acid forms of vitamin A. The retinoids exist as many geometric isomers due to the unsaturated bonds in the aliphatic chain.
Retinol is biological active in a wide range of processes.
It is not biologically active and works as a precursor of active retinoids. Retinol is converted to retinaldehyde and subsequently to retinoic acid.
