The Smooth Endoplasmic Reticulum has a wide range of functions in carbohydrates and lipid synthesis. Phospholipids and cholesterol are necessary for the construction of cell membranes. It serves as a transitional area for vesicles that transport ER products to various destinations. In liver cells, Smooth ER helps detoxify certain compounds. In muscle contraction, and in brain cells it synthesis male and female hormones.
