What is collagen primarily composed of?

Collagen is primarily a structural protein found in various connective tissues throughout the body. It plays a critical role in providing strength, stability, and support to skin, bones, tendons, ligaments, and cartilage. The composition of collagen is unique; it consists mainly of amino acids, forming a fibrous structure which characterizes connective tissues.

The fibrous nature of collagen allows it to withstand tension, which is essential for maintaining the integrity of skin and other tissues. This makes it an integral part of the skin's architecture, influencing elasticity and firmness. In contrast, carbohydrates, fatty acids, and minerals do not constitute collagen’s primary makeup, as collagen is strictly a protein-based material. Thus, understanding that collagen's primary composition is fibrous connective tissue made from protein is fundamental in skincare and regeneration processes.
