Every living organism contains thousands of different proteins, with some research indicating a single human cell can contain up to 10 billion protein molecules. Understanding what are the main subtypes of proteins is essential, as these vital macromolecules perform an immense array of tasks, from catalyzing reactions to providing structural support.

The human body contains an estimated 500,000 different types of proteins, yet four main functional categories encompass the majority of their roles. These four essential types of proteins—structural, enzymatic, transport, and defensive—are critical for virtually every biological process, from cell maintenance to immune defense.
