Wikipedia on Retinyl Palmitate
Retinyl palmitate, or vitamin A palmitate, is a common vitamin supplement, with formula C36H60O2. It is the ester of retinol
(vitamin A) and palmitic acid. It is available in both oral and injectable forms for treatment of vitamin A deficiency, under
the brand names Aquasol A and Palmitate A.
Retinyl palmitate is an alternate for retinyl acetate in vitamin A supplements, and is available in oily or dry forms. It is
a pre-formed version of vitamin A, and can thus be realistically over-dosed, unlike beta-carotene.
It is also commonly added to reduced fat milk, but has been implicated in studies linking milk with prostate cancer
because it reacts with zinc and protein to form an unabsorbable complex.
An alternate spelling, retinol palmitate, which violates the -yl organic chemical naming convention for esters, is also
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).
