One of the endomembrane system's components is the smooth endoplasmic reticulum (SER). Cells that are eukaryotic contain it. Cisternae, which are tubular constructions, make up SER. Ribosomes are not present.

Therefore, it is not related to the synthesis of proteins. Its main duties include the production of lipids, the production of steroid hormones, and the detoxification of toxic metabolic byproducts. The lipids or fats produced by SER aid in the formation of membranes.A membrane system called the endoplasmic reticulum creates a sac-like structure in the cytoplasm of eukaryotic cells. Rough endoplasmic reticulum and smooth endoplasmic reticulum are the two types. The rough endoplasmic reticulum is known as such because it has ribosomes on its surface. The smooth endoplasmic reticulum is crucial for the production of lipids. The smooth endoplasmic reticulum in liver cells houses enzymes that detoxify toxic medicines and metabolic waste. It is crucial for the production and storage of lipids, such as cholesterol and phospholipids.
