The primary structure is the order of amino acids in the protein chain. What kind of bonding is found between the amino acids in this chain?
What kind of bonding can be present in all of the other structure types?
Name one type of bonding that does not occur in the primary or secondary structure of the protein.
Many proteins have an important role in catalysing chemical reactions in living organisms. What name is given to these catalysts?
Give two changes in conditions under which these catalysts may be inactivated, and explain the chemical reason for each one.
