What Type of Linkage Occurs Between ACP and the Intermediates

Question

What type of linkage occurs between ACP and the intermediates in fatty acid biosynthesis?
A) an ester
B) a thioester
C) an amide
D) an ether
E) an acetal

Accepted Answer

The linkage between ACP and the intermediates in fatty acid biosynthesis is a thioester bond. This bond is formed between the thiol group (-SH) of ACP and the carboxyl group (-COOH) of the intermediate, and it plays a key role in transferring the growing fatty acid chain between different enzymes in the pathway.
