Final answer:
Lipids are made up of monomer subunits called fatty acids.
Step-by-step explanation:
Lipids are made up of monomer subunits called fatty acids. Fatty acids can be saturated or unsaturated, depending on the number of hydrogen atoms they contain. Examples of lipids include triglycerides, phospholipids, and steroids.
Lipids are a diverse group of organic molecules that are hydrophobic, meaning they do not dissolve in water. They serve various essential functions in living organisms and are crucial components of cell membranes, energy storage, and signaling molecules.
