Question
Chapter 23, Problem 17P
Interpretation Introduction
Interpretation:
A reaction scheme to show the product of the acyl-CoA dehydrogenase reaction that reacts with FAD should be written.
Concept Introduction:
Hypoglycin is a toxic amino acid and a metabolite and it acts as a acyl-CoA dehydrogenase substrate. For this reaction, the product acts as an irreversible inhibitor for acyl CoA dehydrogenase. It inhibits the enzyme by reacting with FAD.

- Understanding the Oxidation of Glucose and Its Products in the TCA Cycle Glycolysis, the pyruvate dehydrogenase reaction, and the TCA cycle result in complete oxidation of a molecule of glucose to CO2. Review the calculation of oxidation numbers for individual atoms in any molecule, and then calculate the oxidation numbers of the carbons of glucose, pyruvate, the acetyl carbons of acetyl-CoA. and the metabolites of the TCA cycle to convince yourself that complete oxidation of glucose involves removal of 24 electrons and that each acetyl-CoA through the TCA cycle gives up 8 electrons.arrow_forwardExtending the Mechanism of Methylmalonyl-CoA Mutase to Similar Reactions Based on the mechanism for the methylmalonyl-CoA mutase (see problem 14), write reasonable mechanisms for the following reactions shown.arrow_forwardUnderstanding the Stoichiometry of Cholesterol Synthesis Write a Balanced, stoichiometric reaction for the synthesis of cholesterol from acetyl-CoA.arrow_forward
