What is a phospholipid

What does a phospholipid look like? The phosphate group, a charged molecule composed of Phpsohorus and oxygen, not only changes the structure of the lipid, but also its function. For a better visual representation, triglycerides look like a tridentate fatty acid shell, while phospholipids look like a bipedal head.

Important Points to Remember Phospholipids are made up of several components, including two fatty acids, a glycerol unit, a phosphate group, and a polar molecule. The polar region (head) on the phosphate group of the phospholipid is attracted to water. Phospholipids are an important and vital part of cell membranes.
