Proteins play a crucial role in the human body, serving as the building blocks for tissues and organs. They are essential for growth, repair, and maintenance of body cells. Proteins are also integral in the formation of enzymes and hormones, which regulate various bodily functions.
Additionally, proteins contribute to immune function, transporting molecules throughout the body, and providing structure and support to cells. Without adequate protein intake, the body cannot perform these vital functions effectively, leading to various health issues.
