Ethanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes (particularly those of procaryotes), e.g., phosphatidylethanolamine. It is also used in messenger molecules such as palmitoylethanolamide, which has an effect on CB1 receptors.thanolamine is the second-most-abundant head group for phospholipids, substances found in biological membranes (particularly those of procaryotes), e.g., phosphatidylethanolamine.

MITOCHONDRIA. The mitochondria are round tube-like organelles that are surrounded by a double membrane, with the inner membrane being highly folded. the mitochondria are often referred to as the powerhouse of the cell. the mitochondria releases food energy from food molecules to be used by the cell.
Lysosomes. are the recycling crew of the cell. They contain hydrolytic. enzymes which break nutrient particles into smaller pieces so that other. organelles can use these fragments as a source of energy.They destroy. bacteria and organic debris that enter the cell from the extracellular fluid.he. central vacuole. is always near the middle of the cell. Plants store. water and other materials in these storage tanks, keeping them separate. from the cytosol. Central vacuoles perform the same functions as a. lysosome, breaking down nutrients and organelles into useable energy. components.
