一般描述

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. Retinoids also exist as retinyl esters such as retinyl propionate, retinyl acetate and retinyl palmitate.

应用

Retinyl acetate has been used:

a control diet to study its effect at different developmental periods in fish larvae
to study its inhibitory effects on Mycobacterium avium subspecies paratuberculosis (MAP) strains
as an internal standard in high performance liquid chromatography (HPLC) to quantify vitamin A in fortified milk

生化/生理作用

Retinyl esters provide pools of vitamin A that are converted into retinol and other retinoids as required. Retinyl acetate is used in a wide range of biological applications. It acts as a chemopreventive agent. Retinyl acetate also has antineoplastic property.

The effect of the feeding period on larval development was investigated in European sea bass larvae by considering the expression level of some genes involved in morphogenesis. Larvae were fed a control diet except during three different periods (period A:
