FooDB Name | phosphoenolpyruvate |
---|
Description | Phosphoenolpyruvate, also known as pep or 2-(phosphonooxy)-2-propenoic acid, is a member of the class of compounds known as phosphate esters. Phosphate esters are organic compounds containing phosphoric acid ester functional group, with the general structure R1P(=O)(R2)OR3. R1,R2 = O,N, or halogen atom; R3 = organyl group. Phosphoenolpyruvate is soluble (in water) and an extremely strong acidic compound (based on its pKa). Phosphoenolpyruvate can be found in a number of food items such as okra, endive, chestnut, and dandelion, which makes phosphoenolpyruvate a potential biomarker for the consumption of these food products. Phosphoenolpyruvate can be found primarily in blood, cellular cytoplasm, and saliva, as well as in human prostate tissue. Phosphoenolpyruvate exists in all living species, ranging from bacteria to humans. In humans, phosphoenolpyruvate is involved in several metabolic pathways, some of which include glycolysis, amino sugar metabolism, gluconeogenesis, and glycogenosis, type IC. Phosphoenolpyruvate is also involved in several metabolic disorders, some of which include glycogen storage disease type 1A (GSD1A) or von gierke disease, salla disease/infantile sialic acid storage disease, phosphoenolpyruvate carboxykinase deficiency 1 (PEPCK1), and pyruvate dehydrogenase complex deficiency. Phosphoenolpyruvate (2-phosphoenolpyruvate, PEP) as the ester derived from the enol of pyruvate and phosphate. It exists as an anion; the parent acid, which is only of theoretical interest, is phosphoenolpyruvic acid. PEP is an important intermediate in biochemistry. It has the highest-energy phosphate bond found (−61.9 kJ/mol) in living organisms, and is involved in glycolysis and gluconeogenesis. In plants, it is also involved in the biosynthesis of various aromatic compounds, and in carbon fixation; in bacteria, it is also used as the source of energy for the phosphotransferase system . |
