What is the main role of collagen in the human body?

Collagen plays a crucial role in forming connective tissue throughout the human body. As the main structural protein, it provides strength, elasticity, and support to various tissues, including skin, tendons, ligaments, cartilage, and bones. By forming a framework for these tissues, collagen contributes to their integrity and resilience, allowing them to withstand stretching and mechanical stress.

While other proteins and molecules have specific functions, such as transporting oxygen or regulating metabolism, collagen's primary function distinctly centers around the structural support and cohesion of connective tissues. Therefore, its importance is underscored in maintaining overall body structure, facilitating movement, and promoting healing by providing the necessary scaffolding for tissue regeneration.
