The tem1 retinoids was introduced in order to determine the large group of compounds of natural or synthetic origin differing from retinol in details of the structure in the ring or side chain. The name vitamin A often refers to all retinoids showing a similar qualitative biological activity as retinol. Retinal and all-trans-retinoic acid - the products of retinal oxidation - are the two most important his metabolites.
