What percentage of human body protein does collagen represent?

• A. 25%
• B. 30%
• C. 35%
• D. 40%

Answer: (B)

Collagen represents approximately 30% of the total protein in the human body. It is the most abundant protein and serves a critical structural role, providing strength and elasticity to connective tissues such as skin, tendons, ligaments, and cartilage. Since collagen plays such a key role in maintaining the integrity of these tissues, its substantial presence in the body's protein composition is crucial for overall health and functionality, particularly in relation to movement and flexibility. This is why the choice of 30% accurately reflects collagen's role within human physiology.
