Structure and Properties of Peptides

Q1: The peptide bond in proteins is

A only found between proline residues

B usually cis unless proline is the next amino acid

ANS:C - usually trans unless proline is the next amino acid

Yes, the peptide bond is a planner but not of a stearic hindrance. And peptide bond is also a non-polar btw alfa amino group of amino acid and alpha-carbonyl group of another amino acid.
