ANSWER

2,4-Dienoyl-CoA reductase (uses NADPH). 2,4-Dienoyl-CoA reductase reduces conjugated double bonds using NADPH, enabling isomerase and hydratase to process polyunsaturated chains in beta-oxidation.

Practice questions

1 of 47Practice questions for this set
A patient with exercise intolerance is found to carry a homozygous missense variant in the gene encoding medium-chain acyl-CoA dehydrogenase (MCAD), a mitochondrial enzyme used during beta-oxidation of medium-chain fatty acids. During a supervised 18-hour fast, plasma measurements were obtained. Based on the experimental setup, what is the most likely effect of the mutation on metabolism?
