It may be remembered that yeast assimilates nitrogenous compounds in some of their simpler forms—amides and the like.
About 30 % of the amide protons exchanged with deuterons after 3 hours.
The interactions are strongest when the interacting amide groups vibrate with the same frequency.
A final example are the amide groups of the protein backbone.
Moreover, the crystal structures reveal networks of hydrogen bonds among amide groups of glutamine and asparagine side-chains.
A protected amide hydrogen can be regarded as ' closed ' to exchange.
The next system on the energy scale is an amide ester.
It depends, however, on the secondary structure of the backbone and is therefore the amide vibration that is most commonly used for secondary-structure analysis.
