LysoPE(0:0/20:0) is a lysophosphatidylethanolamine or a lysophospholipid. The term lysophospholipid (LPL) refers to any phospholipid that is missing one of its two O-acyl chains. Thus, LPLs have a free alcohol in either the sn-1 or sn-2 position. The prefix lyso- comes from the fact that lysophospholipids were originally found to be hemolytic however it is now used to refer generally to phospholipids missing an acyl chain. LPLs are usually the result of phospholipase A-type enzymatic activity on regular phospholipids such as phosphatidylcholine or phosphatidic acid, although they can also be generated by the acylation of glycerophospholipids or the phosphorylation of monoacylglycerols. Some LPLs serve important signaling functions such as lysophosphatidic acid. Lysophosphatidylethanolamines (LPEs) can function as plant growth regulators with several diverse uses. (LPEs) are approved for outdoor agricultural use to accelerate ripening and improve the quality of fresh produce. They are also approved for indoor use to preserve stored crops and commercial cut flowers. As a breakdown product of phosphatidylethanolamine (PE), LPE is present in cells of all organisms.

C25H52NO7P (509.34812120000004)

LysoPC(17:0) is a lysophospholipid (LyP). It is a monoglycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. Lysophosphatidylcholines can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) position. Fatty acids containing 16, 18 and 20 carbons are the most common. LysoPC(17:0), in particular, consists of one chain of margaric acid at the C-1 position. The margaric acid moiety is derived from butter, milk and fat of ruminants. Lysophosphatidylcholine is found in small amounts in most tissues. It is formed by hydrolysis of phosphatidylcholine by the enzyme phospholipase A2, as part of the de-acylation/re-acylation cycle that controls its overall molecular species composition. It can also be formed inadvertently during extraction of lipids from tissues if the phospholipase is activated by careless handling. In blood plasma significant amounts of lysophosphatidylcholine are formed by a specific enzyme system, lecithin:cholesterol acyltransferase (LCAT), which is secreted from the liver. The enzyme catalyzes the transfer of the fatty acids of position sn-2 of phosphatidylcholine to the free cholesterol in plasma, with formation of cholesterol esters and lysophosphatidylcholine. Lysophospholipids have a role in lipid signaling by acting on lysophospholipid receptors (LPL-R). LPL-Rs are members of the G protein-coupled receptor family of integral membrane proteins.

C26H56NO6P (509.3845046)

1-Octadecyl-sn-glycero-3-phosphocholine is an intermediate in the ether lipid metabolism pathway. 1-Octadecyl-sn-glycero-3-phosphocholine is irreversibly produced from 2-acetyl-1-(9Z-octadecenyl)-sn-glycero-3-phosphocholine via the enzyme 1-alkyl-2-acetylglycerophosphocholine esterase (EC 3.1.1.47). 1-Octadecyl-sn-glycero-3-phosphocholine is an ether phospho-ether lipid. Ether lipids are lipids in which one or more of the carbon atoms on glycerol are bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage. Plasmalogens are glycerol ether phospholipids. They are of two types, alkyl ether (-O-CH2-) and alkenyl ether (-O-CH=CH-). Dihydroxyacetone phosphate (DHAP) serves as the glycerol precursor for the synthesis of plasmalogens. Three major classes of plasmalogens have been identified: choline, ethanolamine and serine derivatives. Ethanolamine plasmalogen is prevalent in myelin. Choline plasmalogen is abundant in cardiac tissue. Usually, the highest proportion of the plasmalogen form is in the ethanolamine class with rather less in choline, and commonly little or none in other phospholipids such as phosphatidylinositol. In choline plasmalogens of most tissues, a higher proportion is often of the O-alkyl rather than the O-alkenyl form, but the reverse tends to be true in heart lipids. In animal tissues, the alkyl and alkenyl moieties in both non-polar and phospholipids tend to be rather simple in composition with 16:0, 18:0 and 18:1 (double bond in position 9) predominating. Ether analogues of triacylglycerols, i.e. 1-alkyldiacyl-sn-glycerols, are present at trace levels only if at all in most animal tissues, but they can be major components of some marine lipids. 1-Octadecyl-sn-glycero-3-phosphocholine is an intermediate in the ether lipid metabolism pathway. 1-Octadecyl-sn-glycero-3-phosphocholine is irreversibly produced from 2-acetyl-1-(9Z-octadecenyl)-sn-glycero-3-phosphocholine via the enzyme 1-alkyl-2-acetylglycerophosphocholine esterase (EC 3.1.1.47). 1-Octadecyl-sn-glycero-3-phosphocholine is an ether phospho-ether lipid.
