Smooth endoplasmic reticulum is almost entirely devoted to the manufacture of lipids.
Smooth ER not only manufactures lipids, but can store some ribosomes too.
The smooth endoplasmic reticulum (SER) is primarily involved in the synthesis of lipids, including phospholipids and steroid hormones. It also plays a key role in detoxifying drugs and storing calcium ions, which are critical for muscle function. This organelle is essential for maintaining overall cellular health and homeostasis.
