PA(16:0/18:1(9Z)) is a phosphatidic acid. It is a glycerophospholipid in which a phosphate moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidic acids can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PA(16:0/18:1(9Z)), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of oleic acid at the C-2 position. The palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats, while the oleic acid moiety is derived from vegetable oils, especially olive and canola oil. Phosphatidic acids are quite rare but are extremely important as intermediates in the biosynthesis of triacylglycerols and phospholipids. Indeed, the concentration of phosphatidic acids is often over-estimated in tissues and biofluids as it can arise by inadvertent enzymatic hydrolysis during inappropriate storage or extraction conditions during analysis. The main biosynthetic route of phosphatidic acid in animal tissues involves sequential acylation of alpha-glycerophosphate by acyl-coA derivatives of fatty acids. PAs are biologically active lipids that can stimulate a large range of responses in many different cell types, such as platelet aggregation, smooth muscle contraction, in vivo vasoactive effects, chemotaxis, expression of adhesion molecules, increased tight junction permeability of endothelial cells, induction of stress fibres, modulation of cardiac contractility, and many others. Diacylglycerols (DAGs) can be converted to PAs by DAG kinases and indirect evidence supports the notion that PAs alter the excitability of neurons. Phospholipase Ds (PLDs), which catalyze the conversion of glycerolphospholipids, particularly phosphatidylcholine, to PAs and the conversion of N-arachidonoyl-phosphatidylethanolamine (NAPE) to anandamide and PAs are activated by several inflammatory mediators including bradykinin, ATP and glutamate. PAs activate downstream signaling pathways such as PKCs and mitogen-activated protein kinases (MAPKs), which are linked to an increase in sensitivity of sensory neurons either during inflammation or in chronic pain models.

Sphingomyelin (d18:1/14:0) or SM(d18:1/14:0) is a type of sphingolipid found in animal cell membranes, especially in the membranous myelin sheath which surrounds some nerve cell axons. It usually consists of phosphorylcholine and ceramide. SM(d18:1/14:0) consists of a sphingosine backbone and a myristic acid chain. In humans, sphingomyelin is the only membrane phospholipid not derived from glycerol. Like all sphingolipids, SM has a ceramide core (sphingosine bonded to a fatty acid via an amide linkage). In addition, it contains one polar head group, which is either phosphocholine or phosphoethanolamine. The plasma membrane of cells is highly enriched in sphingomyelin and is considered largely to be found in the exoplasmic leaflet of the cell membrane. However, there is some evidence that there may also be a sphingomyelin pool in the inner leaflet of the membrane. Moreover, neutral sphingomyelinase-2, an enzyme that breaks down sphingomyelin into ceramide, has been found to localize exclusively to the inner leaflet further suggesting that there may be sphingomyelin present there. Sphingomyelin can accumulate in a rare hereditary disease called Niemann-Pick Disease, types A and B. Niemann-Pick disease is a genetically-inherited disease caused by a deficiency in the enzyme sphingomyelinase, which causes the accumulation of sphingomyelin in spleen, liver, lungs, bone marrow, and the brain, causing irreversible neurological damage. SMs play a role in signal transduction. Sphingomyelins are synthesized by the transfer of phosphorylcholine from phosphatidylcholine to a ceramide in a reaction catalyzed by sphingomyelin synthase.
