Question

Which of the following reduces double bond, forming saturated acyl ACP?

(a) β-ketoacyl ACP reductase

(b) β-hydroxyacyl ACP dehydratase

(c) Enoyl ACP reductase

(d) Malonyl co-A ACP transferase

This question was posed to me during an interview for a job.

Asked question is from Biosynthesis of Fatty Acids and Eicosanoids in portion Lipid Biosynthesis, Biosynthesis of Amino Acids, Nucleotides and Related Molecules of Biochemistry

Answer 1

The correct option is (c) Enoyl ACP reductase

For explanation: Malonyl co-A ACP transferase transfers malonyl group from co-A to ACP.

β-Ketoacyl ACP reductase reduces β-keto group to β-hydroxyl group.

β-Hydroxyacyl ACP dehydratase removes H2O from β-hydroxyl ACP, creating a double bond.
