Pyruvic acid (CH 3 COCOOH) is the simplest of the alpha-keto acids, with a carboxylic acid and a ketone functional group. Pyruvate , the conjugate base , CH 3 COCOO − , is an intermediate in several metabolic pathways throughout the cell.

Pyruvate undergoes oxidative decarboxylation in which it loses its carboxyl group (as carbon dioxide) to form acetyl-CoA, giving off 33.5 kJ/mol of energy. The oxidative conversion of pyruvate into acetyl-CoA is referred to as the pyruvate dehydrogenase reaction. It is catalyzed by the pyruvate dehydrogenase complex. Other conversions between ...
Phosphoenolpyruvate (2-phosphoenolpyruvate, PEP) is the carboxylic acid derived from the enol of pyruvate and phosphate. It exists as an anion. PEP is an important intermediate in biochemistry. It has the highest-energy phosphate bond found (−61.9 kJ/mol) in organisms, and is involved in glycolysis and gluconeogenesis.
Ethyl pyruvate is small molecule with both ketone and ester functionality. The molecule has no hydrogen donors, but three atoms that are hydrogen receptors. Three of the bonds are rotatable and there are no stereocenters. [4] The molecule has two carbonyl carbons, which can act as electrophiles, as well as three α-hydrogens.
Pyruvate dehydrogenase complex. Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes that converts pyruvate into acetyl-CoA by a process called pyruvate decarboxylation. [1] Acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration, and this complex links the glycolysis metabolic pathway to the citric ...
Most epigenetic clocks were created using blood tissue, Apsley says, so using oral tissue to try to determine biological age didn’t result in an accurate number, based on the study findings.
The pyruvate produced by glycolysis is an important intermediary in the conversion of carbohydrates into fatty acids and cholesterol. [7] This occurs via the conversion of pyruvate into acetyl-CoA in the mitochondrion. However, this acetyl-CoA needs to be transported into cytosol where the synthesis of fatty acids and cholesterol occurs.
