Question

Starting from acetyl-COA provide the structure of the fatty acid formed from using 3 units of methylmalonyl-COA

Answer 1

Acetyl CoA is the starting substrate of Fatty acid synthesis. Acteyl CoA is converted to Malonyl CoA via Acetyl CoA carboxylase and then to Malonyl ACP via Malonyl ACP in two step reaction. Fatty acids can be elongated using malonyl CoA into long chain FA. In the question, 3 units of methylmalonyl-COA is used.

So the reaction would be : Acetyl CoA + 3 Methylmalonyl CoA

The following image shows the reaction.
