Biology primary structure bonds

WebThe primary protein structure is the sequence of amino acids in a polypeptide chain. This sequence is determined by the DNA, more precisely by specific genes. This sequence is essential because it affects both the shape and the function of proteins. If only one amino acid in the sequence is changed, the shape of the protein changes. WebThe first of these is the primary structure, which is the number and sequence of amino acids in a protein’s polypeptide chain or chains, beginning with the free amino group and maintained by the peptide bonds connecting each amino acid to the next. The primary structure of insulin, composed of 51 amino acids, is shown in Figure 2.1.1.
