Where Are Lipids Synthesized?

The endoplasmic reticulum (ER) is the main site for lipid synthesis.

Are lipids synthesized in smooth ER?

The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

Where are lipids and proteins synthesized in a cell?

In the cell, there are so many cell organelles having different functions, out of which endoplasmic reticulum plays an important role in the synthesis of lipids and proteins, where lipids are synthesized in the smooth endoplasmic reticulum, while proteins are synthesized in the rough endoplasmic reticulum.
