General description:	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.
