Moreover, similar analysis on some hydrogen bonded complexes confirms that beyond this angle the acceptor atom Y starts interacting with the atomic basin on X. However, conclusions based on bond lengths and angles have to be treated with care and as the IUPAC recommendation points out that ...
Most generally, the hydrogen bond can be viewed as a metric dependent electrostatic scalar field between two or more intermolecular bonds. This is slightly different than the intramolecular bound states of, for example, covalent or ionic bonds; however, hydrogen bonding is generally still a bound ...
The main-chain mimic of the Lys makes five hydrogen bonds with the 310 helix of CDRH2 in H/L (Fig. 5f iv.) but only one in A/B (Fig S10c), consistent with differences in ordering and previously noted weaker interactions (see above). Torsion angle modification of the lysine side ...
How are ionic and covalent bonds different from hydrogen bonds? What makes a covalent bond? How is a hydrogen bond different from a covalent bond? How do electrons move in covalent bonds? How do hydrogen atoms make a covalent bond?
Hydrogen bonds: Hydrogen bonds are formed as a result of the attractive force occurring between a hydrogen atom which is already covalently bonded to a very electronegative atom like oxygen, fluorine, or nitrogen and another very electronegative atom like those. This other atom can be oxyg...
Hydrogen bonds are impor- tant for maintaining amyloid fibrils and their mechanical properties; other non-covalent bonds (e.g., electrostatic interactions, π-π interactions, etc.) can also affect strength depending on the amyloid fibril structures. 4.2.2. Simulations Experimental studies have ...

The hydries are reducing in nature and the reducing power is related to the stability of A-H bonds. The hydrides are covalent and low boiling. Their boiling points depends on their ability to from hydrogen bond and their molecular size which decide the intermolcular forces in the hydrides ....
(D) Active site structure of rHypBA1 bound to 2, with hydrogen bonds and coordination shown as in panel C. The covalent complex of rBtGH146 with aziridine 2 displayed the anomeric-mimicking carbon C1 at covalent bond distance to the thiol group of C416. This points to the expected regio...
These structures might also be important to the cohesive strength of the adhesive through the considerable number of hydrogen bonds between cross-β-sheets [[47], [48], [49], [50]]. The molecular features of these amyloid-like proteins with silk homology found in barnacles as well as in ...
