Malonate

Malonic acid, disodium salt, 1-(14)C-labeled

C3H4O4 (104.011)


Malonic acid (IUPAC systematic name: propanedioic acid) is a dicarboxylic acid with structure CH2(COOH)2. The ionised form of malonic acid, as well as its esters and salts, are known as malonates. For example, diethyl malonate is malonic acids ethyl ester. The name originates from Latin malum, meaning apple. Malonic acid is the archetypal example of a competitive inhibitor: it acts against succinate dehydrogenase (complex II) in the respiratory electron transport chain.; Malonic acid (IUPAC systematic name: propanedioic acid) is a dicarboxylic acid with structure CH2(COOH)2. The ionised form of malonic acid, as well as its esters and salts, are known as malonates. For example, diethyl malonate is malonic acids ethyl ester. The name originates from the Greek word ????? (malon) meaning apple. Propanedioic acid is found in many foods, some of which are green bell pepper, red bell pepper, common beet, and sweet orange.

C3H4O4 (104.011)


3-hydroxypyruvic acid, also known as beta-hydroxypyruvate or oh-pyr, belongs to beta hydroxy acids and derivatives class of compounds. Those are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. 3-hydroxypyruvic acid is soluble (in water) and a moderately acidic compound (based on its pKa). 3-hydroxypyruvic acid can be found in a number of food items such as fox grape, black mulberry, elliotts blueberry, and silver linden, which makes 3-hydroxypyruvic acid a potential biomarker for the consumption of these food products. 3-hydroxypyruvic acid can be found primarily in blood and urine. 3-hydroxypyruvic acid exists in all living organisms, ranging from bacteria to humans. In humans, 3-hydroxypyruvic acid is involved in the glycine and serine metabolism. 3-hydroxypyruvic acid is also involved in several metabolic disorders, some of which include dihydropyrimidine dehydrogenase deficiency (DHPD), 3-phosphoglycerate dehydrogenase deficiency, hyperglycinemia, non-ketotic, and non ketotic hyperglycinemia. Hydroxypyruvic acid is a pyruvic acid derivative with the formula C3H4O4 and a neutral charge with an atomic mass of 104.06146 . Hydroxypyruvic acid is an intermediate in the metabolism of Glycine, serine and threonine. It is a substrate for Serine--pyruvate aminotransferase and Glyoxylate reductase/hydroxypyruvate reductase. Hydroxypyruvic acid (β-Hydroxypyruvic acid) is an intermediate in the metabolism of glycine, serine and threonine. Hydroxypyruvic acid is a substrate for serine-pyruvate aminotransferase and glyoxylate reductase/hydroxypyruvate reductase. Hydroxypyruvic acid is involved in the metabolic disorder which is the dimethylglycine dehydrogenase deficiency pathway.
