What organelle performs lipid synthesis?


Quick Answer

The organelle that performs lipid synthesis is the smooth endoplasmic reticulum. There are two steps in this process: fatty acid synthesis and lipid assembly.

Full Answer

The endoplasmic reticulum (ER) is a type of organelle found in cells. Rough ER has a bumpy appearance because it is covered with ribosomes, which are used to make proteins. Smooth ER is smooth because it is not covered with ribosomes.

Before the cell can produce lipids, it must form fatty acids. It does this by using acetyl coenzyme A (acetyl-CoA) to form long alkyl chains. During lipid synthesis, the fatty acid chains are combined with the polar head group and glycerol 3-phosphate. Lipids store energy, protect the vital organs from injury, and prevent heat loss in the human body.
