16-Hydroxyhexadecanoic acid
16-Hydroxyhexadecanoic acid, also known as 16-hydroxypalmitic acid, is a hydroxylated fatty acid where the terminal (omega) carbon has been hydroxylated. In animal tissues, a family of enzymes termed cytochromes P450s are involved in fatty acid oxidation, hydroxylating with high specificity at the energetically unfavourable terminal (omega) or omega-1 carbons. Hydroxy fatty acids primarily come from the consumption of plant products (vegetables or fruits) or cow’s milk. Omega hydroxy fatty acids are found in the structure of suberin, a lipid polyester present in plant cell walls, and of cutin, a lipid polyester which is a component of the plant cuticle. These apoplastic structures are important plant-environment interfaces that act as barriers limiting water and nutrient loss and protecting plants from radiation and pathogens. 16-Hydroxyhexadecanoic acid and 18-hydroxystearic acid are particularly abundant in cutin in the plant cuticle. 16-Hydroxyhexadecanoic acid has been proposed as a biomarker of beer consumption. 16-hydroxy-hexadecanoic acid, also known as 16-hydroxypalmitic acid or 16-oh 16:0, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 16-hydroxy-hexadecanoic acid is considered to be a fatty acid lipid molecule. 16-hydroxy-hexadecanoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 16-hydroxy-hexadecanoic acid can be synthesized from hexadecanoic acid. 16-hydroxy-hexadecanoic acid is also a parent compound for other transformation products, including but not limited to, (3R)-3,16-dihydroxypalmitic acid, oscr#28, and 16-hydroxyhexadecanoyl-CoA. 16-hydroxy-hexadecanoic acid can be found in a number of food items such as other cereal product, hyacinth bean, red rice, and elliotts blueberry, which makes 16-hydroxy-hexadecanoic acid a potential biomarker for the consumption of these food products.
