Protein makes up what portion of bone tissue?

Protein constitutes around one third of bone tissue. This portion primarily includes collagen, a crucial protein that provides structural support and strength to bones. Collagen fibers form a framework that allows minerals such as calcium and phosphorus to deposit, giving bones their hardness and rigidity.

The protein component plays a vital role not only in the structure of bone but also in maintaining overall bone health. Understanding this ratio is essential for professionals in sports nutrition and health, as it highlights the importance of adequate protein intake for individuals involved in physical activities, particularly in terms of muscle and skeletal repair, as well as bone density and integrity.

The other options do not accurately reflect the composition of bone tissue. For instance, while one half and two thirds suggest a greater reliance on protein, the reality is that bones are composed primarily of mineral content, with a substantial yet lesser portion being protein.
