Question

Fatty acid synthesis is regulated in 2 ways. What are they, how do they function, and which one contains the "committed step"?

Answer 1

The fatty acid synthesis has certain processes like condensation, reduction dehydration and reduction until 16 carbon chains are formed.

The fatty acid synthesisis the production of fatty acids.

The fatty acid synthasebis responsible fir the release of NADPH and acetyl CoA which is the key factor for the productions of fatty acids.Namely saturated and unsaturated fatty acids are formed. This are straight chained fatty acidsThe branches chain are saturated fatty acids.

It is regulated by two main enzymes like acetyl CoA carboxylase and fatty acid synthase.

In fatty acid synthesis the the acrtyl CoA catalysts the action of Malonyl CoA.After this the four step fatty acid assembling is done which are long chain.

The glycolotic pathway is responsible for formation of fatty acids from acety CoA.This process generally takes place in cytoplasm of a cell.

In fatty acid synthesis the Malonyl coenzyme A formation is considered to the committed step as it cannot be reversed.
