A shorter hydrogen bond, for instance, indicates stronger hydrogen bonding and a relatively weaker covalent bond. This was reflected, as expected, in lower spectroscopic frequencies for the H–F ...
Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...
The sharing of electrons between atoms is called a covalent bond, which holds the atoms together as a molecule. A covalent bond happens if the attractions are strong enough in both atoms and if each ...
Researchers have chemically linked 2D materials using a molecular "velcro," resulting in a device with improved optoelectronic properties. The device, made of palladium nanosheets covalently ...
Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...
A lanthanide–carbon triple bond has been created for the first time, specifically a bond between cerium and carbon, ...

A covalent bond links lysine and cysteine in proteins together under oxidizing conditions, stabilizing them - MSNThese new bonds were only discovered in 2016, and are formed when the end of a lysine side-chain is linked to the end of a cysteine side-chain with an oxygen atom linking them together. The NOS ...
However, in 1931, Linus Pauling theorized that a covalent bond could exist with atoms sharing a single electron. However, creating a new single-electron chemical bond isn’t easy.
Drugs that make covalent bonds to biological targets have been around for more than a century. Aspirin. Anti-inflammatory drug. First sold in 1899. Penicillin V. Antibiotic. Discovered in 1928.
