proteins. Proteins are essential nutrients that serve as the main building blocks for the body, providing structure and support to tissues, organs, muscles, and cells. They are involved in various physiological processes and functions, including growth, repair, and maintenance of body tissues, catalyzing chemical reactions as enzymes, transporting molecules, and serving as signals and receptors. Proteins are comprised of amino acids, which are linked together in specific sequences to form long chains. They can be obtained from various food sources, including meats, dairy products, legumes, nuts, and seeds.
