From theCambridge English Corpus The interactions are strongest when the interactingamidegroups vibrate with the same frequency. From theCambridge English Corpus A final example are theamidegroups of the protein backbone. From theCambridge English Corpus Moreover, the crystal structures reveal networks of hydrogen bonds amongamidegroups of glutamine and asparagine side-chains. From theCambridge English Corpus A protectedamidehydrogen can be regarded as ' closed ' to exchange. From theCambridge English Corpus The next system on the energy scale is anamideester. From theCambridge English Corpus It depends, however, on the secondary structure of the backbone and is therefore theamidevibration that is most commonly used for secondary-structure analysis.

From theCambridge English Corpus The amount of exchangeableamideprotons can vary with a broad range. From theCambridge English Corpus The resultingamidegroup is as short as the ethynyl group, but the conformational degree of freedom is larger and coupling yields are very low.
