Vitamin A palmitate is the ester of retinol (vitamin A) and palmitic acid, a major component of palm oil.Also known as retinyl palmitate, it is a synthetic alternate for retinyl acetate in vitamin A supplements. The Vitamin A molecule is very unstable by itself. To create a more stable configuration, it is reacted with methyl palmitate.Vitamin A 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. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucous membranes and skin.It is commonly known as the anti-infective vitamin. It is required for normal functioning of the immune system. It has antioxidant properties, offering protection to cell membranes that can be damaged by free radical molecules created during the body's oxidation process.Vitamin A is important for vision, where a deficiency in retinol results in impaired adaptation to darkness, known as night blindness.
