Proteins are large, complex macromolecules composed of long chains of amino acids, which are linked together by peptide bonds. They play a crucial role in various biological functions, including catalyzing metabolic reactions, providing structural support, and facilitating communication within and between cells. The specific sequence of amino acids determines a protein's unique structure and function. Proteins can be classified into various categories, such as enzymes, antibodies, and hormones, each serving distinct roles in the organism.
