The molecule is a 1-(alk-1-enyl)-2-acyl-sn-glycero-3-phosphoethanolamine zwitterion in which the alk-1-enyl and acyl groups are specified as (1Z)-octadecenyl and (9Z)-octadecenoyl respectively; major species at pH 7.3. It is a 1-(Z)-alk-1-enyl-2-acyl-sn-glycero-3-phosphoethanolamine zwitterion and a 1-O-(1Z-octadecenyl)-2-acyl-sn-glycero-3-phosphoethanolamine zwitterion. It derives from a 1-O-octadecyl-2-oleoyl-sn-glycero-3-phosphoethanolamine zwitterion. It is a tautomer of a 1-(1Z-octadecenyl)-2-(9Z-octadecenoyl)-sn-glycero-3-phosphoethanolamine.
