Metabolite Identification
Common Name16-Hydroxyhexadecanoic acid
Description16-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.
