产品说明

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

包装

10, 100 g in glass bottle

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.
