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.
They are just special proteins that can break large molecules into small molecules. Different types of enzymes can break down different nutrients: carbohydrase or amylase enzymes break down starch into sugar. protease enzymes break down proteins into amino acids.his is only a start to the process of digestion, as chewed pieces of food are still too large to be absorbed by the body. Food has to be broken down chemically into really small particles before it can be absorbed.
