Fatty acid synthesis lecture - This lecture explains about the synthesis of fatty acids from acetyl coA and glycerol to make complex fat molecules in cell.
where fatty acid synthesis takes place?
Fatty acids are synthesized in the cytosol, whereas acetyl CoA is formed from pyruvate in mitochondria. Hence, acetyl CoA must be transferred from mitochondria to the cytosol. Mitochondria, however, are not readily permeable to acetyl CoA.
How is fatty acid synthesis regulated?
Acetyl-CoA is formed into malonyl-CoA by acetyl-CoA carboxylase, at which point malonyl-CoA is destined to feed into the fatty acid synthesis pathway. Acetyl-CoA carboxylase is the point of regulation in saturated straight-chain fatty acid synthesis, and is subject to both phosphorylation and allosteric regulation.
How is acetyl CoA transported out of the mitochondria?
This citrate is transported from the mitochondria to the cytosol, thus transporting the acetyl-CoA in the form of citrate. Once in the cytosol, the citrate is converted back to oxaloacetate, which is then reduced to malate.
Where does lipogenesis occur in the body?
Lipogenesis takes place in the cytoplasm of your fat cells and liver cells. The process begins with acetyl-CoA, also referred to as acetyl coenzyme A, which is a molecule that is formed from the metabolism of glucose
