The regulation of pyruvate dehydrogenase is shown in Figure 12-9. Pyruvic acid (CH 3 COCOOH) is the simplest of the alpha-keto acids, with a carboxylic acid and a ketone functional group. In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into the mitochondrial matrix (the middle region of the mitochondria) (Figure 1).

The colorimetric determination of phosphorus, with special reference to blood phosphorus. It is an irreversible oxidation process in which the carboxyl group is removed from pyruvate as a molecule of CO 2 and the two remaining carbons become the acetyl group of Acetyl-CoA.

A short summary of this paper. Pyruvate oxidation. During pyruvate oxidation, a total of 3 ATPs are formed (after the entry of NADH to the electron transport chain). Pyruvate,Pi dikinase (PPdk) catalyzes the reversible phosphorylation of pyruvate and inorganic phosphate, using ATP as a substrate (see Chapter 3). This also produces NADH. Steps three and four are both oxidation and decarboxylation steps, which release electrons that reduce NAD + to NADH and release carboxyl groups that form CO 2 molecules.
