A paper titled "Functional implications of unusual NOS and SONOS covalent linkages found in proteins," by Matthew D. Lloyd, ...

Uranium forms an unusually strong triple covalent bond with nitrile groups, confounding predictions about the bond strength of actinides compared with the remainder of the periodic table. Elements ...

Although drugs that make covalent bonds with their biological targets are as old as the pharmaceutical industry, intentionally designing molecules that make such bonds is relatively new.

It is weaker than a covalent bond and can be either inter- or intramolecular. Hydrogen bonds are responsible for the lattice structure of frozen water, for example, and for joining the two strands ...
