Common NameLysoPA(i-22:0/0:0)
DescriptionLysoPA(i-22:0/0:0) is a lysophosphatidic acid. It is a glycerophospholipid in which a phosphate moiety occupies a glycerol substitution site. Lysophosphatidic acids can have different combinations of fatty acids of varying lengths and saturation attached at the C-1 (sn-1) or C-2 (sn-2) position. Fatty acids containing 16 and 18 carbons are the most common. LysoPA(i-22:0/0:0), in particular, consists of one chain of isodocosanoic acid at the C-1 position. Lysophosphatidic acid is the simplest possible glycerophospholipid. It is the biosynthetic precursor of phosphatidic acid. Although it is present at very low levels only in animal tissues, it is extremely important biologically, influencing many biochemical processes.
