From theCambridge English Corpus None of the sulfide ions make any favorablehydrogenbondto the protein. From theCambridge English Corpus Its frequency depends on the strength of thehydrogenbond. From theCambridge English Corpus The reason for this is easily understood since ammonia forms ahydrogenbondthat imidazole (or histidine) cannot form. From theCambridge English Corpus Furthermore, simulated annealing does not provide well-defined conformations, but the different conformations that are observed are consistent with several possiblehydrogenbondcombinations. From theCambridge English Corpus The transition is opposed by the loss in conformational entropy, and driven by gains in free energy due to hydrophobic burial andhydrogenbondformation. From theCambridge English Corpus The environment of the iron-sulfur cluster is not exceptional having, on average, onehydrogenbondper liganding cysteine and otherwise a surrounding hydrophobic environment. From theCambridge English Corpus Note thehydrogenbondbetween the exocyclic amine of the 3h cytosine base and the non-bridging oxygen of the phosphate at the exchange point. From theCambridge English Corpus Unlike the alcohols, general anaesthetics cannothydrogenbondto phospholipid headgroups. From theCambridge English Corpus The second condition ensures that thehydrogenbondis more or less linear. From theCambridge English Corpus The second distance restraint restricts the angle of thehydrogenbond. From theCambridge English Corpus To represent the key feature of a polar solvent like water, the capability ofhydrogenbondformation has to be represented. From theCambridge English Corpus Formally, thehydrogenbondhas to be treated as a combination of a dipole-dipole interaction and a charge transfer reaction. From theCambridge English Corpus The relation should be particularly useful in studies of enzyme catalytic sites or other protein-ligand interactions in whichhydrogenbondstrength may play a key role. From theCambridge English Corpus Correlation withhydrogenbondlength. From theCambridge English Corpus These examples are from corpora and from sources on the web.
