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.

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.

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.
An adenine on one strand can line tip its H-bond donors and acceptors with a thymine on the opposite strand, forming a total of 2 H bonds: and a guanine can line up similarly with a cytosine, forming 3 H-bonds.

These follow three rules: each base can only participate in at most one h-bond; h-bonds may not cross; and the bases that form an h-bond may not be too close to each other in the primary structure.
In human deoxyhemoglobin, a sulfate anion is found anchored to the [beta]-chains by a complex network of H-bonds and electrostatic interactions with the N-terminus and [beta]Lys82.
