Macromolecules

Large biological molecules, known as macromolecules, play critical roles in biological systems. Lipids, primarily made up of carbon, hydrogen, and oxygen, serve as energy storage, insulate the body, and cushion organs.

Macromolecules

Macro-molecules

Proteins

4 parts of Protein Structure
