C33H46N4O6 (594.3417176)

Stercobilin is the tetrapyrrole chemical compound that is primarily responsible for the brown color of feces. It was originally isolated from feces in 1932. Stercobilin is formed through the reduction of its parent compound stercblinogen. Urobilinogen is actually generated through the degradation of heme, the red pigment in haemoglobin and red blood cells (RBCs). RBCs have a life span of about 120 days. When the RBCs have reached the end of their useful lifespan, the cells are engulfed by macrophages and their constituents recycled or disposed of. Heme is broken down when the heme ring is opened by the enzyme known as heme oxygenase, which is found in the endoplasmic reticulum of the macrophages. The oxidation process produces the linear tetrapyrrole known as biliverdin along with ferric iron (Fe3+), and carbon monoxide (CO). In the next reaction, a second methylene group (located between rings III and IV of the porphyrin ring) is reduced by the enzyme known as biliverdin reductase, producing bilirubin. Bilirubin is significantly less extensively conjugated than biliverdin. This reduction causes a change in the color of the biliverdin molecule from blue-green (vert or verd for green) to yellow-red, which is the color of bilirubin (ruby or rubi for red). In plasma virtually all the bilirubin is tightly bound to plasma proteins, largely albumin, because it is only sparingly soluble in aqueous solutions at physiological pH. In the sinusoids unconjugated bilirubin dissociates from albumin, enters the liver cells across the cell membrane through non-ionic diffusion to the smooth endoplasmatic reticulum. In hepatocytes, bilirubin-UDP-glucuronyltransferase (bilirubin-UGT) adds 2 additional glucuronic acid molecules to bilirubin to produce the more water-soluble version of the molecule known as bilirubin diglucuronide. The bilirubin diglucuronide is transferred rapidly across the canalicular membrane into the bile canaliculi where it is then excreted as bile into the large intestine. The bilirubin is further degraded (reduced) by microbes present in the large intestine to form a colorless product known as urobilinogen. Urobilinogen that remains in the colon can either be reduced to stercobilinogen and finally oxidized to stercobilin, or it can be directly reduced to stercobilin. Stercobilin is responsible for the brown color of human feces. Stercobilin is then excreted in the feces. It is a microbial metabolite.

Cholyltryptophan

2-[(1-Hydroxy-4-{5,9,16-trihydroxy-2,15-dimethyltetracyclo[8.7.0.0,.0,]heptadecan-14-yl}pentylidene)amino]-3-(1H-indol-3-yl)propanoate

C35H50N2O6 (594.3668680000001)

Cholyltryptophan 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. Cholyltryptophan consists of the bile acid cholic acid conjugated to the amino acid Tryptophan 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 Cholyltryptophan, 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). Cholyltryptophan 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).

PA(8:0/18:1(12Z)-2OH(9,10))

[(2R)-2-{[(9S,10S,12Z)-9,10-dihydroxyoctadec-12-enoyl]oxy}-3-(octanoyloxy)propoxy]phosphonic acid

C29H55O10P (594.353266)

PA(8:0/18:1(12Z)-2OH(9,10)) is an oxidized phosphatidic acid (PA). Oxidized phosphatidic acids are glycerophospholipids in which a phosphate moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidic acids belong to a group of biomolecules that have a role as signaling molecules. The biosynthesis of oxidized lipids is mediated by several enzymatic families, including cyclooxygenases (COX), lipoxygenases (LOX) and cytochrome P450s (CYP). Non-enzymatically oxidized lipids are produced by uncontrolled oxidation through free radicals and are considered harmful to human health (PMID: 33329396). As is the case with diacylglycerols, phosphatidic acids can have many different combinations of fatty acids of varying lengths, saturation and degrees of oxidation attached at the C-1 and C-2 positions. PA(8:0/18:1(12Z)-2OH(9,10)), in particular, consists of one chain of one octanoyl at the C-1 position and one chain of 9,10-hydroxy-octadecenoyl at the C-2 position. Phospholipids are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. Similarly to what occurs with phospholipids, the fatty acid distribution at the C-1 and C-2 positions of glycerol within oxidized phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. Oxidized PAs can be synthesized via three different routes. In one route, the oxidized PA is synthetized de novo following the same mechanisms as for PAs but incorporating oxidized acyl chains (PMID: 33329396). An alternative is the transacylation of one of the non-oxidized acyl chains with an oxidized acylCoA (PMID: 33329396). The third pathway results from the oxidation of the acyl chain while still attached to the PA backbone, mainly through the action of LOX (PMID: 33329396).
