WebDec 18, 2016 · The structure and function of an enzyme are intimately related. Enzymes, like all proteins, have 4 levels of protein structure. Primary structure is formed by the sequence of amino acids in the polypeptide chain. Secondary structure is formed by interactions between adjacent amino acids that create motifs like beta-sheets and alpha-helices. WebThe Central Role of Enzymes as Biological Catalysts A fundamental task of proteins is to act as enzymes —catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.
