GENERAL HISTOLOGY

Detailed explanation-1: -It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

Detailed explanation-2: -The endoplasmic reticulum (ER) is the main site for lipid synthesis.

Detailed explanation-3: -Structural lipids are mostly synthesized in the endoplasmic reticulum (ER), from which they are actively transported to the membranes of other organelles.

Detailed explanation-4: -The ER and Golgi apparatus together constitute the endomembrane compartment in the cytoplasm of eukaryotic cells. The endomembrane compartment is a major site of lipid synthesis, and the ER is where not only lipids are synthesized, but membrane-bound proteins and secretory proteins are also made.

Detailed explanation-5: -Hepatocytes synthesize triglycerides, cholesterol, and phospholipids on the smooth endoplasmic reticulum (note its abundance in this micrograph).
