Pyruvate
A crucial intermediate in the metabolism of proteins and carbohydrates is the three-carbon compound pyruvate. In addition, it contributes to the synthesis of ATP, the energy currency of cells. In addition to the fermentation of some amino acids, the breakdown of glucose and other sugars results in the production of pyruvate. Pyruvate is transformed into acetyl-CoA in cells, where it then enters the Krebs cycle to produce ATP. Other significant substances like glucose, lactate, and ethanol can be produced from pyruvate.
