Among these conformations, a guanine quadruplex (G4) can form a planar assembly of G's through Hoogsteen hydrogen bonds [5]. Successive G-planes stack on top of each other and form a structure that may be stabilized by the presence of a cation [6]. G4 usually forms from four tracts ...

Thus, more water molecules may have the opportunity to enter the protein and form new hydrogen bonds with hydroxyl groups in the proteins24. This may increase the water-holding capacity of decolored proteins. In addition, several studies have reported that hydrogen peroxide treatment exposes the ...
To perform disulfide bonds reduction and cysteine alkylation, the beads were resuspended in denaturation buffer (7 M urea, 20 mM HEPES) and DTT (1 mM) was added for 45 min at room temperature. Then iodoacetamide (4 mM) was added and incubated for 45 min at room temperature....
Gels obtained through chemical interactions are generally resistant, as they are mainly formed by covalent bonds (primary forces), while gels resulting from physical interactions are less resistant, as they are maintained through different secondary forces, such as hydrogen bonds, hydrophobic interactions...
The lengths of the H-bonds are given in Å and shown with bold italic numbers. Full size image At the same time, the concavity in the central part of the pentamer at the extracellular side is organized differently in ErNaR and KR2 (Fig. 4b). In general, while in KR2 this region ...
it has a high tensile strength. Through the formation of internal and exterior hydrogen bonds, the glucose units and different bacterial cellulose fibrils interact tightly to produce a crystalline structure, resulting in the compacting of fibres that are completely water-insoluble but can be hydrated6...

Considering these are non-covalent bonds, they are incredibly weak when considered individually, but can derive to highly ...
