Palmitate is the major component of palm oil. The word palmitate is from the French "palmitique", the pith of the palm tree.
An alternate spelling, retinol palmitate, which violates the -yl organic chemical naming convention for esters, is also frequently seen.
Retinyl palmitate is a synthetic alternate for retinyl acetate in vitamin A supplements, and is available in oily or dry forms. It is a common vitamin supplement, available in both oral and injectable forms for treatment of vitamin A deficiency, under the brand names Aquasol A, Palmitate A and many others. It is a pre-formed version of vitamin A, and can thus be realistically over-dosed, unlike beta-carotene.
Palmitate is an antioxidant and a vitamin A compound added to low fat milk and other dairy products to replace the vitamin content lost through the removal of milk fat. Palmitate is attached to the alcohol form of vitamin A, retinol, in order to make vitamin A stable in milk.
 Retinyl palmitate is also a constituent of some topically-applied skin care products. After its absorption into the skin, retinyl palmitate is converted to retinol, and ultimately to retinoic acid (the active form of vitamin A present in Retin-A).
