Common Name9,10-Epoxy-18-hydroxy-octadecanoic acid
Description9,10-epoxy-18-hydroxy-octadecanoic acid, also known as 9,10-epoxy-18-hydroxystearate, is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. 9,10-epoxy-18-hydroxy-octadecanoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 9,10-epoxy-18-hydroxy-octadecanoic acid can be found in a number of food items such as wheat, deerberry, common beet, and rocket salad, which makes 9,10-epoxy-18-hydroxy-octadecanoic acid a potential biomarker for the consumption of these food products.
