The O―H distance (bond length) is 95.7 picometres (9.57 × 10−11metres, or 3.77 × 10−9inches). Because an oxygen atom has a greaterelectronegativitythan a hydrogen atom, the O―H bonds in the water molecule are polar, with the oxygen bearing a partial negative charge (δ−) ...

The H2O molecule is electrically neutral, but the positive and negative charges are not distributed uniformly. This is illustrated by the gradation in color in the schematic diagram here. The electronic (negative) charge is concentrated at the oxygen end of the molecule, owing partly to the non...
There exists an order-to-disorder transition for this condensed phase at ~480–490 K, with a sharp reduction in the number of hydrogen bonds and increase in the entropy. Fast diffusion of the encapsulated water demonstrates anomalous temperature dependence, indicating the solid-to-fluid nature ...
The H-bonding information is obtained from analysis of the hydrated LIFM-CL1-H2O single-crystal at low temperature of 150 K. As seen fromFig. 2andSupplementary Fig. 2, the coordinating water molecule (O6) is located in a micropore (<3 Å) and forms HBs with the uncoordinating carb...
Thus, benzofuroxans are considered to be NO-releasing prodrugs whose biological activity is caused by action on sGC, which in turn initiates the formation of the cGMP messenger molecule. Compared to other NO donors, benzofuroxan has certain advantages due to the slow release of the NO molecule...
In order to investigate qualitatively the effects of H-bonds on the spectroscopy of cytosine, we decided to compare the predictions of the simple chromophore in the PCM with those for a cluster in which all of its H-bonds capabilities were saturated. In practice, we placed a water molecule ...

Model Energy Landscapes and the Force-Induced Dissociation of Ligand-Receptor Bonds We discuss models for the force-induced dissociation of a ligand-receptor bond, occurring in the context of cell adhesion or single molecule unbinding forc... T Strunz,K Oroszlan,I Schumakovitch,... - 《Biophys...
The thirteen conjugated double bonds present in the ASX molecule are responsible for its red colour and, to some extent, for its antioxidant activity (Higuera-Ciapara, Félix-Valenzuela, & Goycoolea, 2006; Santos-Sánchez et al., 2020). Microalgae (mainly Haematococcus pluvialis) is expected to...
