Proteins

Proteins are essential natural polymers made of amino acids, crucial for healthy living. They serve as enzymes controlling cellular reactions and form structural materials in animals. Proteins are composed of 20 different amino acids, which can polymerize through condensation reactions to form polypeptides. Digestion breaks proteins into amino acids for reassembly into new proteins. Proteins have primary, secondary, and tertiary structures, with DNA coding for their unique sequences. Structural proteins like collagen build animal bodies, while enzymes catalyze reactions. Overall, proteins are vital for life, supporting both structural and functional roles in organisms.
