Proteins are essential macronutrients composed of amino acids, crucial for the growth, maintenance, and repair of body tissues, as well as forming enzymes, hormones, and antibodies. Fats are essential macronutrients; they provide concentrated energy, are vital for cell membrane structure, aid in the absorption of fat-soluble vitamins, and provide essential fatty acids.
