Product Description
Retinyl Palmitate is a naturally-occurring phenyl analogue of retinol (vitamin A) with potential antineoplastic and chemopreventive activities. As the most common form of vitamin A taken for dietary supplementation, retinyl palmitate binds to and activates retinoid receptors, thereby inducing cell differentiation and decreasing cell proliferation. This agent also inhibits carcinogen-induced neoplastic transformation, induces apoptosis in some cancer cell types, and exhibits immunomodulatory properties.
All-trans-retinyl palmitate is an all-trans-retinyl ester obtained by formal condensation of the carboxy group of palmitic (hexadecanoic acid) with the hydroxy group of all-trans-retinol. It is a retinyl palmitate and an all-trans-retinyl ester. It derives from an all-trans-retinol.
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 constituent of intra ocular treatment for dry eyes at a concentration of 138 ug/g (VitA-Pos) by Ursapharm. It is a pre-formed version of vitamin A; therefore, the intake should not exceed the Recommended Dietary Allowance (RDA). Overdosing preformed Vitamin A forms such as retinyl palmitate leads to adverse physiological reactions (hypervitaminosis A).
Retinyl palmitate is used as an antioxidant and a source of vitamin A 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).
