Detailed explanation-1: -Collagen is an abundant structural protein in all animals. In humans, collagen comprises one-third of the total protein, accounts for three-quarters of the dry weight of skin, and is the most prevalent component of the extracellular matrix (ECM).

Detailed explanation-2: -Collagen is the most abundant protein in the body. Its fiber-like structure is used to make connective tissue. Like the name implies, this type of tissue connects other tissues and is a major component of bone, skin, muscles, tendons, and cartilage.

Detailed explanation-3: -Collagen is a rigid, inextensible fibrous protein that is composed of three intertwined polypeptide chains and is a principal constituent of connective tissue in animals, including tendons, cartilage, bones, teeth, skin, and blood vessels. Collagen is the most abundant protein in vertebrates.

Detailed explanation-4: -Collagens are the most abundant proteins in mammals.
