What is a primary function of proteins in the human body?

Proteins play a crucial role in the human body, primarily functioning to build and repair tissues. This function is essential for growth, healing, and maintaining the overall structure and function of muscles, organs, and other biological tissues. Proteins are made up of amino acids, which are the building blocks necessary for synthesizing new tissues as well as replacing damaged ones. This process is vital for recovery from injuries, muscle maintenance, and overall body management.

In addition to their role in tissue building and repair, proteins are also involved in various biological functions such as enzyme activity, hormone production, and immune responses. While proteins can be utilized for energy if necessary, their primary role is not energy provision; rather, they are predominantly dedicated to maintaining and improving physical structure and function.
