What is the function of proteins in the body?

The function of proteins in the body is multifaceted, but one of their primary roles is to repair and build tissues. Proteins are made up of amino acids, which are the building blocks of body tissues. When the body undergoes wear and tear, injury, or growth, proteins contribute to the repair process by providing the necessary components to rebuild and strengthen tissues, such as muscles, skin, and organs.

In addition to tissue repair and building, proteins are involved in numerous other functions, such as enzyme catalysis, immune response, and transporting molecules. However, the foundational aspect of their role in maintaining and developing structural integrity within the body is why their contribution to tissue repair and growth is particularly significant.
