Descrizione

Descrizione generale

Retinyl palmitate or vitamin A palmitate is a retinoid, 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. Retinyl esters provide pools of vitamin A that are converted into retinol and other retinoids as needed.

Applicazioni

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

Azioni biochim/fisiol

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