Sure! Here are two structural characteristics that triglycerides and phospholipids have in common:
-
Fatty Acids: Both triglycerides and phospholipids are made up of fatty acids. These fatty acids are long chains of carbon and hydrogen atoms.
-
Glycerol Backbone: Both types of molecules contain a glycerol backbone, which is a three-carbon molecule that serves as the foundation to which the fatty acids are attached.
These common features help define them as lipids, which are important for storing energy and forming cell membranes.
