Pauling and Corey’s studies of the peptide bond showed that:

#SCPH05 I Biotechnology

  1. at pH 7, many different peptide bond conformations are equally probable.

  2. peptide bonds are essentially planar, with no rotation about the C—N axis.

  3. peptide bonds in proteins are unusual, and unlike those in small model compounds.

  4. peptide bond structure is extraordinarily complex.
