H-Bond

A former savings bond in the United States that paid interest on its principal semi-annually. Unlike Series E bonds, which paid interest only at redemption, H-bonds provided bondholders with current income on their investments. H-bonds were issued at face value, were exempt from state and local taxes, and had a fixed interest rate. They were issued between 1952 and 1979 and were replaced by the Series HH bond in 1980.

Figure 9 compares the hydration number derived from the MD simulations (RDF and geometrical H-bonds) with the average hydration number calculated from the thermodynamic properties for hydrated CuCl x n[H.sub.2][O.sup.0] (n = 1-14) species derived by Migdisov et al.
"It offers a new paradigm in perovskite design as further explorations beyond the tolerance factor limit could prevail for cationic blends while preserving a 3D structure with improved stability through increased number of H-bonds within the inorganic framework -- a problem that we are now close to solving."

Docking studies against CDK-2 revealed that all PCNPs (except neoamphimedine and varamine A) form H-bonds with CDK-2.
Thus, biomolecules are capable of establishing H-bonds with water and to play the role of matrix for giant crystal lattices of water, called clusters.

Both of them are responsible for the formation of oxyanion hole during the enzymatic activation on binding of the substrate and makes strong H-bonds with the substrate.
When acetazolamide goes from the monomer form to the dimer or to the water cluster, alterations in the vibrational spectra, due to formation of H-bonds, are estimated.
Formation of the H-bonds in 1 and 2 shifts the electronic density along the molecular backbone of the dye and this effect leads to hindering rotation of the rhodanine moiety around the C=C bond of the central conjugated system to achieve the stable isomer form intrinsic of the dyes 1a and 2a.
According to the docking poses shown in Figure 5, T2384 has n interactions with residues Phe264 and Phe363, hydrogen bonds (H-bonds) with residues Cys285 and Lys367, and hydrophobic contact with other nine residues.
Backbone H-bonds L9Y24 and L11-F22 (PB1 numbering) were crucial for stabilizing the beta-hairpin conformation.
Recall last month's "not-really-accurate-but-mentally-helpful" analogy of H-bonds as being like tiny magnets.
