What are the two major functions of protein in the body?

The functions of protein in the body are vital and encompass several roles, with growth and development and tissue repair being two of the most significant. Proteins are essential macromolecules made up of amino acids, which the body uses as building blocks for the synthesis of new cells and tissues. This makes them critical for growth, especially in children and adolescents, as well as for the maintenance of body tissues throughout life.

When tissue is damaged or during recovery from exercise, proteins play an important role in repairing muscles and other types of tissues through a process known as protein synthesis. This function not only helps in recovering from injuries but also supports the continual renewal of cells, contributing to overall health and well-being.

While proteins have several other roles, such as assisting in enzyme and hormone production, the primary emphasis in this context is on growth, development, and the repair of body tissues. This underscores the direct relationship between protein intake, tissue health, and the body’s ability to maintain and repair itself effectively.
