Примери за amide

• 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.

• About 50-60 % of the amide hydrogens could be exchanged with deuteriums within 24 hours.

• The amount of exchangeable amide protons can vary with a broad range.

• The resulting amide group is as short as the ethynyl group, but the conformational degree of freedom is larger and coupling yields are very low.

• The contribution of internal coordinates to these normal modes will generally alter when the amide group is incorporated into a polypeptide.

• Intensities and other spectral parameters of infrared amide bands of polypeptides in the - and random forms.

• The conformational sensitivity of the amide vibrations has long been used to assess the secondary structure of proteins in general, and membrane proteins in particular.

• Binding of the co-factor makes the holorepressor more stable as evidenced by slower amide exchange rates.

• Combined ab initio and free energy calculations to study reactions in enzymes and solution : amide hydrolysis in trypsin and aqueous solution.
