1-O-(15-carboxypentadecyl)-2-O-acetylglycero-3-phosphorylcholine

PAF C-16 is a naturally occurring phospholipid produced upon stimulation through two distinct pathways known as the “remodeling” and ''de novo'' pathways. It is a potent mediator of neutrophil migration and the production of reactive oxygen species and IL-6. Pathological processes involving PAF include necrotizing enterocolitis, inflammation, asthma, and allergy. PAF C-16 Carboxylic acid is modified with a carboxylic acid group terminating the C-16 alkyl chain. This provides a convenient site for chemical crosslinking.

PAF C-16 carboxylic acid (Acetyl-CPGPC) is a phospholipid that possesses haptenic activity causing production of antibodies reactive with platelet-activating factor (PAF)[1].
