Proteins are large biomolecules made up of one or more long chains of amino acid residues. They perform various functions within organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another
. Proteins are essential for the structure, function, and regulation of the body's tissues and organs. They are made up of hundreds or thousands of smaller units called amino acids, and the sequence of amino acids determines each protein's unique 3-dimensional structure and its specific function
. Protein is found in a wide range of foods, including meat, fish, eggs, dairy products, seeds, nuts, and legumes, and it is important to ensure an adequate intake of protein for the growth and maintenance of cells and tissues
