Question

Which of the following condenses acyl and malonyl groups?

(a) Acyl carrier protein

(b) Acetyl co-A ACP transacetylase

(c) β-ketoacyl ACP synthase

(d) Malonyl co-A ACP transferase

I have been asked this question in an online quiz.

Origin of the question is Biosynthesis of Fatty Acids and Eicosanoids topic in portion Lipid Biosynthesis, Biosynthesis of Amino Acids, Nucleotides and Related Molecules of Biochemistry

Answer 1

Correct answer is (c) β-ketoacyl ACP synthase

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

Acyl carrier protein carries acyl groups in thio-ester linkage.

Acetyl co-A ACP transacetylase transfers acyl group from co-A to cys residue of KS.
