Quick Answer. The smooth endoplasmic reticulum is the organelle responsible for the production of lipids in the cell. This particular reticulum also synthesizes carbohydrates and steroid hormones. The endoplasmic reticulum is made up of membranous sacs and tubules.
Lipids are macromolecules that are made up of long chains of fatty acids, or carbon rings. Important lipids in your body include cholesterol, steroid hormones, triglycerides, and phospholipids. These lipids range in function from hormones, to cell membrane components, to fat storage units.n addition to the very important biologic macromolecules (proteins, lipids, polysaccharides, and nucleic acids), there are three major groups of macromolecules that are important in industry. These are elastomers, fibers and plastics. Elastomers are macromolecules that are stretchy and very flexible.
