Answer 2

Structural protein

Step-by-step explanation:

Collagen is the most abundant protein in the human body. It constitutes most of the tissue of the tendons, ligaments, and dermis, and is abundant in bones, blood vessels, muscles, cartilages, teeth, the capsules of the viscera, and the septa that internally compartmentalize glands, among other sites. Animal collagen is what’s used to make gelatin and animal-derived glue. Leather is composed mainly of collagen.

Collagen is actually a family of related triple-helix proteins; there are at least 29 different kinds of collagen in the body. The type found in any given organ can differ from the types found in others.
