Metabolite Identification
Common Name(Z)-13-Octadecenoic acid
Description(Z)-13-Octadecenoic acid 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. (Z)-13-octadecenoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Within the cell, (Z)-13-octadecenoic acid is primarily located in the membrane (predicted from logP). It can also be found in the extracellular space. (Z)-13-Octadecenoic acid is a constituent of various lipid fractions from fish and some cooked foods.
