A triglyceride has 2 fatty acids and a phosphate, whereas a phospholipid has 3 fatty acids
|
|
|
A triglyceride has 3 fatty acids and a triglyceride has 2 and a phosphate
|
|
|
triglycerides and phospholipids both have 3 fatty acids

Detailed explanation-1: -Like triglycerides, phospholipids have a glycerol backbone. But unlike triglycerides, phospholipids only have two fatty acid molecules attached to the glycerol backbone, while the third carbon of the glycerol backbone is bonded to a phosphate group-a chemical group that contains the mineral phosphorus.
Detailed explanation-2: -Triglycerides and cholesterol are both fatty substances called lipids. But triglycerides are fats; cholesterol is not. Cholesterol is a waxy, odorless substance made by the liver. It is used to build cell walls, helps the nervous system and plays an important role in digestion and hormone production.
Detailed explanation-3: -Image modified from OpenStax Biology. A phospholipid is an amphipathic molecule, meaning it has a hydrophobic part and a hydrophilic part. The fatty acid chains are hydrophobic and do not interact with water, whereas the phosphate-containing group is hydrophilic (because of its charge) and interacts readily with water.
