PG(a-13:0/i-22:0)

[(2S)-2,3-dihydroxypropoxy][(2R)-3-[(10-methyldodecanoyl)oxy]-2-[(20-methylhenicosanoyl)oxy]propoxy]phosphinic acid

C41H81O10P (764.5567056)

PG(a-13:0/i-22:0) is a phosphatidylglycerol - a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylglycerols 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. PG(a-13:0/i-22:0), in particular, consists of one chain of anteisotridecanoic acid at the C-1 position and one chain of isodocosanoic acid at the C-2 position. Phosphatidylglycerol is present at a level of 1-2\\% in most animal tissues, but it can be the second most abundant phospholipid in lung surfactant (up to 11\\% of the total). It is well established that the concentration of phosphatidylglycerol increases during fetal development. Phosphatidylglycerol may be present in animal tissues merely as a precursor for cardiolipin synthesis.

C43H77N2O7P (764.5468102)

SM(d18:1/20:4(6E,8Z,11Z,14Z)+=O(5)) is a type of oxidized sphingolipid found in animal cell membranes. It usually consists of phosphorylcholine and ceramide. SM(d18:1/20:4(6E,8Z,11Z,14Z)+=O(5)) consists of a sphingosine backbone and a 5-oxo-eicosatetraenoyl 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.
