The NOS bond is formed under oxidizing conditions. So far, all examples of this type of bond have been identified using protein crystallography, where X-rays are used to image the folded protein ...

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 ...

Compounds that exhibit a covalent mechanism of action are typically avoided in drug discovery programmes, largely owing to safety concerns. Here, Singh and colleagues present the pharmacological ...

The new bonds had a strength of 45.8 kilocalories per mol (a unit of chemical bonding energy), greater than some covalent bonds. Nitrogen molecules, for example, are made of two nitrogen atoms ...

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 ...

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 ...
