CDP-choline is a member of the class of phosphocholines that is the chloine ester of CDP. It is an intermediate obtained in the biosynthetic pathway of structural phospholipids in cell membranes. It has a role as a human metabolite, a psychotropic drug, a neuroprotective agent, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is a member of phosphocholines and a member of nucleotide-(amino alcohol)s. It is functionally related to a CDP. It is a conjugate base of a CDP-choline(1+). Citicoline is a donor of choline in biosynthesis of choline-containing phosphoglycerides. It has been investigated for the treatment, supportive care, and diagnosis of Mania, Stroke, Hypomania, Cocaine Abuse, and Bipolar Disorder, among others. Citicoline is a nutritional supplement and source of choline and cytidine with potential neuroprotective and nootropic activity. Citicoline, also known as cytidine-5-diphosphocholine or CDP-choline, is hydrolyzed into cytidine and choline in the intestine. Following absorption, both cytidine and choline are dispersed, utilized in various biosynthesis pathways, and cross the blood-brain barrier for resynthesis into citicoline in the brain, which is the rate-limiting product in the synthesis of phosphatidylcholine. This agent also increases acetylcholine (Ach), norepinephrine (NE) and dopamine levels in the central nervous system (CNS). In addition, citicoline is involved in the preservation of sphingomyelin and cardiolipin and the restoration of Na+/K+-ATPase activity. Citicoline also increases glutathione synthesis and glutathione reductase activity, and exerts antiapoptotic effects. Donor of choline in biosynthesis of choline-containing phosphoglycerides.

Ethanolamine

Envision conditioner PDD 9020

C2H7NO (61.0528)


Ethanolamine (MEA), also known as monoethanolamine, aminoethanol or glycinol, belongs to the class of organic compounds known as 1,2-aminoalcohols (or simply aminoalcohols). These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. In pharmaceutical formulations, ethanolamine is used primarily for buffering or preparation of emulsions. Ethanolamine can also be used as pH regulator in cosmetics. Biologically, ethanolamine is an initial precursor for the biosynthesis of two primary phospholipid classes, phosphatidylcholine (PC) and phosphatidylethanolamine (PE). In this regard, ethanolamine is the second-most-abundant head group for phospholipids. Ethanolamine serves as a precursor for a variety of N-acylethanolamines (NAEs). These are molecules that modulate several animal and plant physiological processes such as seed germination, plant–pathogen interactions, chloroplast development and flowering (PMID: 30190434). Ethanolamine, when combined with arachidonic acid (C20H32O2; 20:4, ω-6), can also form the endocannabinoid anandamide. Ethanolamine can be converted to phosphoethanolamine via the enzyme known as ethanolamine kinase. the two substrates of this enzyme are ATP and ethanolamine, whereas its two products are ADP and O-phosphoethanolamine. In most plants ethanolamine is biosynthesized by decarboxylation of serine via a pyridoxal 5-phosphate-dependent l-serine decarboxylase (SDC). Ethanolamine exists in all living species, ranging from bacteria to plants to humans. Ethanolamine has been detected, but not quantified in, several different foods, such as narrowleaf cattails, mung beans, blackcurrants, white cabbages, and bilberries. Ethanolamine, also known as aminoethanol or beta-aminoethyl alcohol, is a member of the class of compounds known as 1,2-aminoalcohols. 1,2-aminoalcohols are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Ethanolamine is soluble (in water) and an extremely weak acidic compound (based on its pKa). Ethanolamine can be found in a number of food items such as daikon radish, caraway, muscadine grape, and lemon grass, which makes ethanolamine a potential biomarker for the consumption of these food products. Ethanolamine can be found primarily in most biofluids, including urine, cerebrospinal fluid (CSF), feces, and saliva, as well as throughout most human tissues. Ethanolamine exists in all living species, ranging from bacteria to humans. In humans, ethanolamine is involved in several metabolic pathways, some of which include phosphatidylcholine biosynthesis PC(20:3(5Z,8Z,11Z)/18:3(6Z,9Z,12Z)), phosphatidylcholine biosynthesis PC(22:5(7Z,10Z,13Z,16Z,19Z)/18:3(6Z,9Z,12Z)), phosphatidylcholine biosynthesis PC(20:4(5Z,8Z,11Z,14Z)/20:0), and phosphatidylethanolamine biosynthesis PE(11D5/9M5). Moreover, ethanolamine is found to be associated with maple syrup urine disease and propionic acidemia. Ethanolamine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Ethanolamine, also called 2-aminoethanol or monoethanolamine (often abbreviated as ETA or MEA), is an organic chemical compound with the formula HOCH2CH2NH2. The molecule is both a primary amine and a primary alcohol (due to a hydroxyl group). Ethanolamine is a colorless, viscous liquid with an odor reminiscent to that of ammonia. Its derivatives are widespread in nature; e.g., lipids . C308 - Immunotherapeutic Agent > C29578 - Histamine-1 Receptor Antagonist KEIO_ID E023

   

2-Hydroxybutyric acid

DL-alpha-Hydroxybutyric acid barium salt

C4H8O3 (104.0473)


2-Hydroxybutyric acid (CAS: 600-15-7), also known as alpha-hydroxybutyrate, is an organic acid derived from alpha-ketobutyrate. alpha-Ketobutyrate is produced by amino acid catabolism (threonine and methionine) and glutathione anabolism (cysteine formation pathway) and is metabolized into propionyl-CoA and carbon dioxide (PMID: 20526369). 2-Hydroxybutyric acid is formed as a byproduct from the formation of alpha-ketobutyrate via a reaction catalyzed by lactate dehydrogenase (LDH) or alpha-hydroxybutyrate dehydrogenase (alphaHBDH). alpha-Hydroxybutyric acid is primarily produced in mammalian hepatic tissues that catabolize L-threonine or synthesize glutathione. Oxidative stress or detoxification of xenobiotics in the liver can dramatically increase the rate of hepatic glutathione synthesis. Under such metabolic stress conditions, supplies of L-cysteine for glutathione synthesis become limiting, so homocysteine is diverted from the transmethylation pathway (which forms methionine) into the transsulfuration pathway (which forms cystathionine). alpha-Ketobutyrate is released as a byproduct when cystathionine is cleaved into cysteine that is incorporated into glutathione. Chronic shifts in the rate of glutathione synthesis may be reflected by urinary excretion of 2-hydroxybutyrate. 2-Hydroxybutyrate is an early marker for both insulin resistance and impaired glucose regulation that appears to arise due to increased lipid oxidation and oxidative stress (PMID: 20526369). 2-Hydroxybutyric acid is often found in the urine of patients suffering from lactic acidosis and ketoacidosis. 2-Hydroxybutyric acid generally appears at high concentrations in situations related to deficient energy metabolism (e.g. birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic acidemia. More recently it has been noted that elevated levels of alpha-hydroxybutyrate in the plasma is a good marker for early-stage type II diabetes (PMID: 19166731). It was concluded from studies done in the mid-1970s that an increased NADH2/NAD ratio was the most important factor for the production of 2-hydroxybutyric acid (PMID: 168632). 2-Hydroxybutyric acid is an organic acid that is involved in propanoate metabolism. It is produced in mammalian tissues (principaly hepatic) that catabolize L-threonine or synthesize glutathione. Oxidative stress or detoxification demands can dramatically increase the rate of hepatic glutathione synthesis. Under such metabolic stress conditions, supplies of L-cysteine for glutathione synthesis become limiting, so homocysteine is diverted from the transmethylation pathway forming methionine into the transsulfuration pathway forming cystathionine. 2-Hydroxybutyrate is released as a by-product when cystathionine is cleaved to cysteine that is incorporated into glutathione. 2-Hydroxybutyric acid is often found in the urine of patients suffering from lactic acidosis and ketoacidosis. 2-Hydroxybutyric acid generally appears at high concentrations in situations related to deficient energy metabolism (e.g., birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic acidemia.

C11H20N4O11P2 (446.0604)


CDP-ethanolamine, also known as cytidine 5’-diphosphoethanolamine, belongs to the class of organic compounds known as CDP-ethanolamines. These are phosphoethanolamines that consist of an ethanolamine having a cytidine 5-diphosphate moiety attached to the oxygen. CDP-ethanolamine is a very strong basic compound (based on its pKa). In humans, CDP-ethanolamine is involved in phosphatidylethanolamine biosynthesis. Outside of the human body, CDP-ethanolamine has been detected, but not quantified in, several different foods, such as Chinese water chestnuts, buffalo currants, red huckleberries, eggplants, and brazil nuts. This could make CDP-ethanolamine a potential biomarker for the consumption of these foods. Cytidine is a molecule (known as a nucleoside) that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a beta-N1-glycosidic bond. [HMDB]. CDP-Ethanolamine is found in many foods, some of which are allspice, hedge mustard, wasabi, and green vegetables.
