What Are the Roles of Proteins in the Body? Exploring the 6 Functions of Body Proteins and the Structures They Build

Proteins are among the most vital biological macromolecules in the human body, playing a central role in nearly every physiological process. From supporting muscle function to enabling immune defenses and catalyzing biochemical reactions, proteins are foundational to life itself. Understanding the functions of proteins in biology allows us to better grasp how the body maintains homeostasis, adapts to stress, repairs itself, and defends against disease. These molecules are not just abstract entities studied in textbooks—they are the architects and laborers of cellular architecture, metabolic balance, and molecular communication.
