LysoPC(22:2(13Z,16Z)/0:0)
LysoPC(22:2(13Z,16Z)) 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(22:2(13Z,16Z)), in particular, consists of one chain of docosadienoic acid at the C-1 position. The docosadienoic acid moiety is derived from animal fats. 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.

3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate
3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate, also known as 3-hexaprenyl-4-hydroxy-5-methoxybenzoate anion, is a member of the class of compounds known as sesterterpenoids. Sesterterpenoids are terpenes composed of five consecutive isoprene units. 3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate can be found in a number of food items such as borage, apricot, red rice, and buffalo currant, which makes 3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate a potential biomarker for the consumption of these food products.

lysophosphatidylcholine 22:2
A lysophosphatidylcholine in which the remaining acyl group contains 22 carbons and 2 double bonds. If R1 is the acyl group and R2 is a hydrogen then the molecule is a 1-acyl-sn-glycero-3-phosphocholine. If R1 is a hydrogen and R2 is the acyl group then the molecule is a 2-acyl-sn-glycero-3-phosphocholine.
