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.
Also in the mouth, an enzyme called salivary amylase begins to break down long starch molecules into maltose. Once the food is ready to be swallowed it is gathered into a ball called a bolus and sends to the part of the bolus called the pharynx.he first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physical broken down, digestive chemicals break the food down into small molecules (chemical digestion). The mouth is the organ in which the process of digestion begins.
