Factors affecting the use of 13Cα chemical shifts to determine, refine, and validate protein structures
(Veterinary and Human Toxicology, 2008-05)
Interest centers here on the analysis of two different, but related, phenomena that affect side-chain conformations and consequently 13Cα chemical shifts and their applications to determine, refine, and validate protein ...
New copolymers of a tautomerizable beta-ketonitrile monomer: synthesis, characterization and solution tautomerism
(Wiley, 2012-10)
The monomer 2-methyl-3-oxo-5-phenyl-4-pentenonitrile (MOP) was prepared by reaction of ethyl cinnamate and propionitrile in alkaline mixture. This monomer exhibits three possible tautomeric forms. The tautomeric equilibria ...
Resonant helical deformations in nonhomogeneous Kirchhoff filaments
