Descripción

General description

Retinyl palmitate or vitamin A palmitate is a retinoid,[1] which is an acid form of vitamin A. Retinoids exist as many geometric isomers due to the unsaturated bonds in the aliphatic chain. Retinyl palmitate is a major storage form of vitamin A found in epidermis.[2] Retinyl esters provide pools of vitamin A that are converted into retinol and other retinoids as needed.[3]

Application

Retinyl palmitate has been used as a standard in high performance liquid chromatography (HPLC).[4] It has also been used to study its effect on brain regeneration in larval Xenopus laevis.[1]

Biochem/physiol Actions

Retinyl palmitate is widely used in pharmaceutical applications.[2] It is also extensively used in cosmetic formulations due to its beneficial effects on the appearance of skin and anti-oxidant properties.[5] Retinyl palmitate acts as a teratogen and affect vertebrate embryogenesis and regeneration.[1] It is added as a source of vitamin A in low fat and skim milks.[6] Retinyl palmitate acts as a chemopreventive or antineoplastic agent.[7]
