1. Select an appropriate description for the structure of the peptide bonds in proteins? Select the single best answer. A. Each peptide bond contains one C-O bond and one N-H bond and the C O and N-H bonds are oriented perpendicular to each other The peptide bonds are highly flexible, allowing proteins to B. fold into diverse 3-dimensional C. D. E. shapes. The bond between hydrogen and nitrogen restricts free rotation of peptide bonds. The peptide bonds are somewhat rigid because the rotation of the C-N bond is restricted When the pH of solution is above 10, the peptide bonds in proteins are positively charge 2.
