Pyruvate is converted to acetyl CoA via the pyruvate dehydrogenase reaction.
It can be converted to CO2 via the TCA Cycle, used for fatty acid synthesis, ketone bodies, cholesterol, steroids, and acetylation (e.g., histones).
Pyruvate is converted to lactate via lactate dehydrogenase (LDH) reaction.
Pyruvate is converted to ethanol via pyruvate decarboxylase and alcohol dehydrogenase.
