It is an anionic phospholipid, a monocarboxylic acid anion and a 1,2-diacyl-sn-glycero-3-phospho-(N-acyl)-serine(2-). It is functionally related to a 1-stearoyl-2-oleoyl-sn-glycero-3-phosphoserine(1-). It is a conjugate base of a N-hexadecanoyl-O-(1-octadecanoyl-2-oleoyl-sn-glycero-3-phospho)-L-serine."}]
