Try This! (True or Flase?) 1. Primary protein structure is stabilized by peptide bonds between a linear sequence of amino acids. 2. Secondary protein structure is stabilized by hydrogen bonds between R groups on adjacent amino acids. 3. Both primary and tertiary protein structure may be stabilized by covalent bonds. 4. All proteins display primary, secondary, and tertiary levels of protein structure.
