Pyruvate is a three-carbon molecule derived from glucose metabolism. It plays a key role in cellular respiration, where it is converted into acetyl-CoA to enter the citric acid cycle for further energy generation.

What causes excess pyruvate in blood?

Insulin is a hormone that is needed for kreb cycle to function properly. In metabolism of glucose are three steps: 1. glycolysis in which the glucose is converted to pyruvate 2. kreb's cycle - pyruvate is converted to oxaloacetate by pyruvate carboxylase enzyme. 3. Electron transport chain. In diabetes when there is deficiency of insulin, kreb's cycle won't work properly and thus the end product of glycolysis i.e pyruvate will be in excess in blood. Excess of pyruvate will lead to deficiency of pyruvate carboxylase which will lead to lactic acidosis. Also in case of anaerobic condition, the pyruvate will be converted to lactate.
