Chapter 16.4, Problem 16.29QAP
Interpretation Introduction
To determine: whether each of the following statements describes primary, secondary, tertiary or quaternary protein structures
- R groups interact to form disulfide bonds or salt bridges.
- Peptide bonds join amino acids in a polypeptide chain
- Several polypeptides in a beta-plated sheet are held together by hydrogen bonds.
- Hydrogen bonding between amino acids in the same polypeptide gives a coiled shape to the protein.
