Detailed explanation-1: -The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

Detailed explanation-2: -Smooth ER is devoted almost exclusively to the manufacture of lipids and in some cases to the metabolism of them and associated products.

Detailed explanation-3: -Lipids are made by enzymes embedded in the membrane of the SER. That’s because they have hydrophobic parts that don’t like the watery inside of the organelle. Meanwhile, the hydrophilic parts of the fats face into the cisternal space.

Detailed explanation-4: -The smooth ER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane. In certain cell types, smooth ER plays an important role in the synthesis of steroid hormones from cholesterol.

Detailed explanation-5: -Its composition has two components: the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER). The SER is generally used for the creation/ storage of lipids and steroids, while the RER plays a significant role in the synthesis of various proteins.
