Study on the turn structure of polypeptides containing glycine and L-proline
Journal of Hebei University of Science and Technology, 2016 The formation of turn structure in peptide chains has direct relations with intramolecular hydrogen bonds, therefore the existence of this bond can be tested to research the turn structure.

Ethyl (E)-3-anilino-2-cyano-3-mercaptoacrylate
Acta Crystallographica Section E, 2008 In the title compound, C12H12N2O2S, there are S—H...N and N—H...O hydrogen-bond interactions. The N—H...O hydrogen bond is bifurcated, with the hydrogen being simultaneously donated to two equivalent O atoms, forming one intra- and one ...

“Hydridic Hydrogen-Bond Donors” Are Not Hydrogen-Bond Donors [PDF]
Journal of the American Chemical SocietyHerein, we dismiss a recent proposal by Civiš, Hobza, and co-workers to modify the IUPAC definition of hydrogen bonds in order to expand the scope from protonic Y-Hδ+ to hydridic Y-Hδ- hydrogen-bond donor fragments [J. Am. Chem. Soc. 2023, 145, 8550].

Supercritical Water is not Hydrogen Bonded [PDF]
Angewandte Chemie, 2020 AbstractThinking about water is inextricably linked to hydrogen bonds, which are highly directional in character and determine the unique structure of water, in particular its tetrahedral H‐bond network. Here, we assess if this common connotation also holds for supercritical water.

A Mechanochromic Hydrogen‐Bonded Rotaxane [PDF]
Macromolecular Rapid Communications, 2020 AbstractTensile forces influence a variety of important biological processes and force sensors are required to study these processes in vivo. Current force sensors are often tailor‐made for a specific application, or activate at much higher forces than those observed at the cellular or tissue level. A versatile force sensor, with tunable mechanical and
