Quizplus · Accepted Answer

Collagen is the most abundant protein in bone matrix, making up about 90% of the organic (non-mineral) component. It provides tensile strength and flexibility to bone tissue. Elastin is not a component of bone matrix, but rather is found in connective tissues such as skin and blood vessels. Keratin is a fibrous protein found in hair, nails, and the outer layer of skin. Bonetin is not a known protein.
