To determine the number of possible stereoisomers for a given compound, follow these steps: Look for carbon atoms bonded to four different groups. These are your chiral centers. Carefully examine the ...

For the first time in 50 years, researchers say they have identified a new category of stereoisomers (Nat. Chem. 2018, DOI: 10.1038/s41557-018-0043-6). The new class is characterized by a bond-angle ...

Proteins are made up of long chains of amino acids, and most proteins have one or more of the sulfur-containing amino acid methionine. Oxidation of the sulfur atom in methionine is an important ...
