<answer>The molecule is an epoxy(hydroxy)icosatrienoate that is the conjugate base of 11-hydroxy-(14R,15S)-epoxy-(5Z,8Z,12E)-icosatrienoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a conjugate base of an 11-hydroxy-(14R,15S)-epoxy-(5Z,8Z,12E)-icosatrienoic acid.</answer>

The molecule is a 1,2-diacyl-sn-glycero-3-phosphoethanolamine in which the acyl groups specified at position 1 and 2 are palmitoyl and (7Z,10Z,13Z,16Z)-docosatetraenoyl respectively. It has a role as a mouse metabolite. It derives from a hexadecanoic acid and an all-cis-docosa-7,10,13,16-tetraenoic acid.
