Question

The long fatty acid chains are formed from

• A. Decomposition of neutral fats.
• B. Conversion of glycerol.
• C. Polymerisation of glycogen.
• D. Polymerisation of 2-carbon compounds.

Answer 1

The correct option is D Polymerisation of 2-carbon compounds.

Fatty acids are synthesized as well as metabolised in groups of two carbon atoms. The acetyl CoA is the chief metabolite. Fatty acid synthesis is the creation of fatty acids from acetyl CoA and Malonyl CoA precursors through action of enzymes called fatty acid synthases.
