The molecule is an (omega-1)-hydroxy fatty acid that is nonadecanoic acid which has been dehydrogenated to introduce a double bond with E configuration between positions 2 and 3 and in which the pro-R hydrogen at position 17 has been replaced by a hydroxy group. It is an (omega-1)-hydroxy fatty acid, a long-chain fatty acid, an alpha,beta-unsaturated monocarboxylic acid and a hydroxy monounsaturated fatty acid.
