Title: Re: Describe the four structural levels of proteins. Post by: chicitygrl on Oct 9, 2013 Primary strucutre: is the sequence of a chain of amino acids that determine the 3D structure, it's linear polymer formed by linking alpha - carboxyl of amino acid to alpha - amino group of another, location of covalent linkages --> disulfide bonds between amino acids
Secondary structure is the sequence of amino acids linked by H - bonds, the poylypeptide chains fold into an alpha - helix and beta - pleated sheet formed by H - bonds between peptide, NH & C, it has areas of folding/coiling within the protein. Tertiary is the certain attractions between alpha helix and beta sheets giving the final 3D structure, Quaternary is has multiple polypeptide chains that make one protein Title: Re: Describe the four structural levels of proteins.
