Phosphoethanolamine

2-Aminoethyl dihydrogen phosphate (acd/name 4.0)

C2H8NO4P (141.0190938)


O-Phosphoethanolamine, also known as PEA, phosphorylethanolamine, colamine phosphoric acid or ethanolamine O-phosphate, belongs to the class of organic compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. O-Phosphoethanolamine is used in the biosynthesis of two different types of phospholipids: glycerophospholipids and sphingolipids. O-Phosphoethanolamine exists in all living species, ranging from bacteria to plants to humans. Within humans, O-phosphoethanolamine participates in a number of enzymatic reactions. In particular, cytidine triphosphate and O-phosphoethanolamine can be converted into CDP-ethanolamine; which is mediated by the enzyme ethanolamine-phosphate cytidylyltransferase. In addition, O-phosphoethanolamine can be biosynthesized from ethanolamine; which is catalyzed by the enzyme choline/ethanolamine kinase. In humans, O-phosphoethanolamine is involved in phosphatidylcholine biosynthesis. O-phosphoethanolamine is also a product of the metabolism of sphingolipids. In particular, sphinglipids are metabolized in vivo to phosphorylethanolamine and a fatty aldehyde, generally palmitaldehyde. Both metabolites are ultimately converted to glycerophospholipids. The lipids are first phosphorylated by a kinase and then cleaved by the pyridoxal-dependent sphinganine-1-phosphate aldolase. Elevated urine levels of O-Phosphoethanolamine or PEA can be used to help in the diagnosis of Hypophosphatasia (HPP). Reference ranges for urinary PEA vary according to age and somewhat by diet, and follow a circadian rhythm. Outside of the human body, O-phosphoethanolamine has been detected, but not quantified in, several different foods, such as oxheart cabbages, anises, shiitakes, abalones, and teffs. Phosphoryl-ethanolamine, also known as colamine phosphoric acid or ethanolamine phosphate, is a member of the class of compounds known as phosphoethanolamines. Phosphoethanolamines are compounds containing a phosphate linked to the second carbon of an ethanolamine. Phosphoryl-ethanolamine is soluble (in water) and a moderately acidic compound (based on its pKa). Phosphoryl-ethanolamine can be found in a number of food items such as pepper (capsicum), black salsify, cascade huckleberry, and redcurrant, which makes phosphoryl-ethanolamine a potential biomarker for the consumption of these food products. Phosphoryl-ethanolamine can be found primarily in most biofluids, including cerebrospinal fluid (CSF), blood, saliva, and feces. Phosphoryl-ethanolamine exists in all living species, ranging from bacteria to humans. In humans, phosphoryl-ethanolamine is involved in several metabolic pathways, some of which include phosphatidylethanolamine biosynthesis PE(22:5(4Z,7Z,10Z,13Z,16Z)/22:5(4Z,7Z,10Z,13Z,16Z)), phosphatidylethanolamine biosynthesis PE(14:0/20:1(11Z)), phosphatidylethanolamine biosynthesis PE(20:2(11Z,14Z)/20:3(8Z,11Z,14Z)), and phosphatidylethanolamine biosynthesis PE(22:5(7Z,10Z,13Z,16Z,19Z)/16:1(9Z)). Phosphoryl-ethanolamine is also involved in few metabolic disorders, which include fabry disease, gaucher disease, and krabbe disease. Moreover, phosphoryl-ethanolamine is found to be associated with traumatic brain injury. Acquisition and generation of the data is financially supported in part by CREST/JST. KEIO_ID E009 Phosphorylethanolamine is an endogenous metabolite. Phosphorylethanolamine is an endogenous metabolite.

Carbamoyl phosphate

Carbamic acid monoanhydride with phosphoric acid

CH4NO5P (140.9827104)


Carbamoyl phosphate is a precursor of both arginine and pyrimidine biosynthesis. It is a labile and potentially toxic intermediate. Carbamoyl phosphate is a molecule that is involved in ridding the body of excess nitrogen in the urea cycle, and also in the synthesis of pyrimidines. It is produced from carbon dioxide, ammonia, and phosphate (from ATP) by the enzyme carbamoyl phosphate synthase. -- Wikipedia.

C4H9Cl2N (141.0112014)


Nornitrogen mustard is a metabolite of cyclophosphamide. Cyclophosphamide (trade names Endoxan, Cytoxan, Neosar, Procytox, Revimmune), also known as cytophosphane, is a nitrogen mustard alkylating agent, from the oxazophorines group. An alkylating agent adds an alkyl group (CnH2n+1) to DNA. It attaches the alkyl group to the guanine base of DNA, at the number 7 nitrogen atom of the imidazole ring. It is used to treat various types of cancer and some autoimmune disorders.
