Possible physiological roles of acetone metabolism in humans
1Theoretical Biology Research Group, Budapest, Hungary.
Abstract:
Recently, the metabolic routes for acetone metabolism have been described. Therefore, acetone cannot further be regarded as a waste product of metabolism. However, its physiological role in biochemical machinery is not clear. Here, an integrative model for the role of acetone metabolism is presented that orders the events occurring in acetonemia in sequence: (i) acetone participates in pH regulation; and (ii) acetone degradation in the liver both contributes to glucostatic function of the liver and provides C3 fragments to peripheral tissues as additional fuel. The model raises a novel approach to the study of the physiological role of acetone metabolism.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
