Which protein is a main constituent of connective tissue?

Collagen is a crucial protein that serves as a primary structural component of connective tissue throughout the body. It provides strength and support to various tissues, including skin, bones, cartilage, and tendons. Collagen fibers are known for their tensile strength and ability to resist stretching, which contributes to the overall integrity and resilience of connective tissues.

In the context of connective tissues, collagen forms a framework that helps to maintain the structure and function of various organs. It also plays a vital role in wound healing and tissue repair, as it is involved in the formation of new tissue at injury sites.

While elastin, another protein involved in connective tissues, provides elasticity and allows tissues to resume their shape after stretching, collagen is more dominant in terms of providing strength and structure. Melanin is a pigment responsible for skin color and UV protection, while keratin is primarily found in skin, hair, and nails, functioning as a protective barrier. Therefore, collagen stands out as the main constituent essential for maintaining the framework and strength of connective tissues across the body.
