Protein </h3>
Proteins are substantial biomolecules and macromolecules made up of one or more extended chains of amino acid residues. Among the many tasks that proteins carry out in living things include catalyzing metabolic processes, replicating DNA, responding to external stimuli, giving cells and organisms structure, and transporting substances. Proteins differ from one another principally in the order of their amino acids, which is determined by the nucleotide sequence of their genes. This causes proteins to fold into a certain 3D structure, which controls their activity. The term "polypeptide" refers to an ordered chain of amino acid residues. One or more lengthy polypeptides must be present in a protein.
