Ketone bodies inhibit leucine degradation in chick skeletal muscle
1Department of Animal Science, University of Alberta, Edmonton, Canada.
Abstract:
1. DL-beta-hydroxybutyrate (4 mM) increased the net rate of leucine transamination and the net rate of 2-oxoisocaproate (KIC) production in extensor digitorum communis muscles from fed chicks. 2. DL-beta-hydroxybutyrate at 1 and 4 mM inhibited leucine oxidative decarboxylation in muscles from fed chicks. 3. Acetoacetate at 1 and 4 mM inhibited leucine oxidative decarboxylation and total leucine oxidation, but increased net KIC production in muscles from fed chicks. 4. Both DL-beta-hydroxybutyrate and acetoacetate at 1 and 4 mM inhibited the net rate of leucine transamination and the rates of leucine oxidative decarboxylation and total leucine oxidation in muscles from 24-hr fasted chicks.

Cell Specific Gene Expression
Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
Depolarizing Blockers: Mechanism of Action
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because succinylcholine...
