| Abstract: | Effect of acetoacetate on 3-hydroxybutyrate oxidation by rat liver mitochondria is described. State 3 respiration is inhibited by acetoacetate, while state 4 respiration is not inhibited, though cytochrome c reduction was decreased. Acetoacetate is also non-competitive inhibitor of 3-hydroxybutyrateoxidase and 3-hydroxybutyrate dehydrogenase activity in frozen-thawed mitochondria. The results are discussed in terms of the thermodynamic hypothesis and control strength method. |
