Notes: 1-O-hexadecyl-2-Dihomo-γ-linolenoyl-sn-glycero-3-PC is a PAF analog which contains dihomo-γ-linolenoate at the sn-2 position rather than the acetate moiety found in PAF C-16. The biological activities of 1-O-hexadecyl-2-dihomo-γ-linolenoyl-sn-glycero-3-PC are not known at present, but may be similar to arachidonoyl PAF C-16 (Item No. 60904).
