• acidity
  • All these observations are consistent with the concept that halogenation increases the acidity of the proximal amino/imino/hydroxyl groups and thus makes them better, i.e. stronger, H-bond donors. (jove.com)
  • bonds
  • Analysis of almost 30000 hydrogen bonds between protein and ligand demonstrates that the length of a hydrogen bond depends on the type of donor-acceptor pair. (jove.com)
  • Interestingly, lengths of hydrogen bonds between a protein and a halogenated ligand are visibly shorter than those estimated for the same family of proteins in complexes with non-halogenated ligands. (jove.com)
  • chemistry
  • Hydrogen Materials Science and Chemistry of Carbon Nanomaterials (Nato Security through Science Series A: 2007 ed. (whsmith.co.uk)
  • It presents the consideration of the physics, chemistry, thermodynamics and kinetics of processes of energy conversion, which occur at hydrogen production, storage, transportation and with its use. (whsmith.co.uk)
  • carbon
  • Above this energy level is a triply degenerate set of MOs that involve overlap of the 2p orbitals on carbon with various linear combinations of the 1s orbitals on hydrogen. (wikipedia.org)
  • structural
  • Taking into account the effect of halogenation on hydrogen bonding is thus important when evaluating structural and/or energetic parameters of ligand-protein complexes. (jove.com)
  • One possibility to study conformational changes a protein undergoes while progressing through its functional cycle is hydrogen- 1 H/ 2 H-exchange in combination with high-resolution mass spectrometry (HX-MS). HX-MS is a versatile and robust method that adds a new dimension to structural information obtained by e.g. crystallography. (jove.com)
  • usually
  • The chlorination of metals is usually not very important industrially since the chlorides are more easily made from the oxides and the hydrogen halide. (wikipedia.org)
  • give
  • Halogenation give the symmetrical derivatives B5H8X, which can be isomerised to place the halide on the base of the square pyramid. (wikipedia.org)
  • industrial
  • It also discusses the pioneering attempts to transform motor transport, airplanes, domestic technics, illumination and industrial manufacture of hydrogen fuel. (whsmith.co.uk)
