Leírás

Általános leírás

Vitamin A usually occurs in food as retinyl esters, which are the pre-formed sources of vitamin A. Retinyl acetate exists as yellow crystals and is insoluble in water. It is soluble in ethanol and oils.

Alkalmazás

Retinyl acetate has been used:

• to study its effects on cochlear development in mice
• as a component of an internal standard to quantify antioxidants in yolk
• as an internal standard to determine serum retinol concentration

Biokémiai/fiziológiai hatások

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. Retinyl esters provide pools of vitamin A that are converted into retinol and other retinoids as needed. Retinyl acetate is used in a wide range of biological applications.

Fizikai forma

Packaged as a melt and may exist as a crystalline solid or a supercooled viscous liquid

Analízis megjegyzés

Activity based on HPLC comparison to USP standard.
