Proteins are large, complex biomolecules critical to life, fundamentally composed of one or more chains of amino acids linked together by peptide bonds. The function of a protein is inextricably linked to its specific three-dimensional folding, which dictates its structure, often comprising primary, secondary, tertiary, and quaternary levels of organization. These molecules are highly versatile, serving roles that include acting as metabolic enzymes to accelerate biochemical reactions, providing structural support to tissues, facilitating the transport of substances within organisms, and participating in cellular communication. Synthesis generally occurs through translation, a process that reads genetic information encoded within messenger RNA to assemble the polypeptide chains.
