LysoPC(0:0/18:0)

(2-{[(2R)-3-hydroxy-2-(octadecanoyloxy)propyl phosphono]oxy}ethyl)trimethylazanium

C26H54NO7P (523.3637704)


LysoPC(0:0/18:0) or LPC(0:0/18:0) is 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. 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. There is also a phospholipase A1, which is able to cleave the sn-1 ester bond. Lysophosphatidylcholine has pro-inflammatory properties in vitro and it is known to be a pathological component of oxidized lipoproteins (LDL) in plasma and of atherosclerotic lesions. Recently, it has been found to have some functions in cell signalling, and specific receptors (coupled to G proteins) have been identified. It activates the specific phospholipase C that releases diacylglycerols and inositol triphosphate with resultant increases in intracellular Ca2+ and activation of protein kinase C. It also activates the mitogen-activated protein kinase in certain cell types.LysoPC(0:0/18:0) has been shown to be protective against lethal sepsis in experimental animals by various mechanisms, including stimulation of neutrophils to eliminate invading pathogens through a peroxide-dependent reaction.

LysoPC(18:0/0:0)

C26H54NO7P (523.3637704)


LysoPC(18:0) 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(18:0), in particular, consists of one chain of stearic acid at the C-1 position. The stearic acid moiety is derived from animal fats, coco butter and sesame oil. 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.

Platelet-activating factor

C26H54NO7P (523.3637704)


Platelet-activating factor, also known as PAF and PC(O-16:0/2:0), is a ubiquitous, potent phospholipid activator and mediator of inflammation that has an important role in the pathogenesis of inflammatory disorders and cardiovascular disease. PAF is able to cause platelet aggregation and anaphylaxis. PAF is synthesized continuously in low quantities in many different types of cells, but especially those involved in host defence, such as macrophages, monocytes, granulocytes, neutrophils, platelets, and endothelial cells. Platelet-activating factor receptor (PAFR) is a G-protein coupled receptor (GPCR) located on the cell membranes of a variety of cells. Once bound to its receptor, PAF mobilizes calcium and activates a wide range of signalling pathways (e.g. phospholipase C-mediated signalling (PMID: 26616844). C16-PAF (PAF (C16)), a phospholipid mediator, is a platelet-activating factor and ligand for PAF G-protein-coupled receptor (PAFR). C16-PAF exhibits anti-apoptotic effect and inhibits caspase-dependent death by activating the PAFR. C16-PAF is a potent MAPK and MEK/ERK activator. C16-PAF induces increased vascular permeability[1][2][3][4][5].

   

Cholylaspartic acid

2-[(1-Hydroxy-4-{5,9,16-trihydroxy-2,15-dimethyltetracyclo[8.7.0.0,.0,]heptadecan-14-yl}pentylidene)amino]butanedioate

C28H45NO8 (523.3145010000001)


Cholylaspartic acid belongs to a class of molecules known as bile acid-amino acid conjugates. These are bile acid conjugates that consist of a primary bile acid such as cholic acid, doxycholic acid and chenodeoxycholic acid, conjugated to an amino acid. Cholylaspartic acid consists of the bile acid cholic acid conjugated to the amino acid Aspartic acid conjugated at the C24 acyl site.Bile acids play an important role in regulating various physiological systems, such as fat digestion, cholesterol metabolism, vitamin absorption, liver function, and enterohepatic circulation through their combined signaling, detergent, and antimicrobial mechanisms (PMID: 34127070). Bile acids also act as detergents in the gut and support the absorption of fats through the intestinal membrane. These same properties allow for the disruption of bacterial membranes, thereby allowing them to serve a bacteriocidal or bacteriostatic function. In humans (and other mammals) bile acids are normally conjugated with the amino acids glycine and taurine by the liver. This conjugation catalyzed by two liver enzymes, bile acid CoA ligase (BAL) and bile acid CoA: amino acid N-acyltransferase (BAT). Glycine and taurine bound BAs are also referred to as bile salts due to their decreased pKa and complete ionization resulting in these compounds being present as anions in vivo. Unlike glycine and taurine-conjugated bile acids, these recently discovered bile acids, such as Cholylaspartic acid, are produced by the gut microbiota, making them secondary bile acids (PMID: 32103176) or microbially conjugated bile acids (MCBAs) (PMID: 34127070). Evidence suggests that these bile acid-amino acid conjugates are produced by microbes belonging to Clostridia species (PMID: 32103176). These unusual bile acid-amino acid conjugates are found in higher frequency in patients with inflammatory bowel disease (IBD), cystic fibrosis (CF) and in infants (PMID: 32103176). Cholylaspartic acid appears to act as an agonist for the farnesoid X receptor (FXR) and it can also lead to reduced expression of bile acid synthesis genes (PMID: 32103176). It currently appears that microbially conjugated bile acids (MCBAs) or amino acid-bile acid conjugates are only conjugated to cholic acid, deoxycholic acid and chenodeoxycholic acid (PMID: 34127070). It has been estimated that if microbial conjugation of bile acids is very promiscuous and occurs for all potential oxidized, epimerized, and dehydroxylated states of each hydroxyl group present on cholic acid (C3, C7, C12) in addition to ring orientation, the total number of potential human bile acid conjugates could be over 2800 (PMID: 34127070).

MALDI generates a stable [M+H]+ ion. Microwave discharge of H2O generates OH*, H* and 3O (triplet O) radicals. These radicals react with the stable [M+H]+ ion and give a mixture of [M+H+H*], [M+H+O]+ and [M+H+OH*]+ ions. These are dissociated to give product ions, which are detected as RID product ions.; The instrument consists of QIT-TOF where Q selects [M+H]+ ion, IT is an ion trap chamber for the reaction of RID, and TOF analyzes the product ions.; This mass spectral data is shown in Figure S5 of the publication.

Phasin, also known as 1-O-octadecyl-2-O-methyl-glycero-phosphocholine or L-et-18-och3, is a member of the class of compounds known as dialkylglycerol-3-phosphocholines. Dialkylglycerol-3-phosphocholines are glycerophosphocholines in which the glycerol moiety is bonded to two aliphatic (saturated or unsaturated) chains through ether linkages. Phasin is practically insoluble (in water) and a moderately acidic compound (based on its pKa). Phasin can be found in soy bean, which makes phasin a potential biomarker for the consumption of this food product.
