In chemistry, isomers are compounds with the same molecular formula but different structural formulas. The word is derived from the Greek ισομερης, isomerès; isos = "equal", méros = "part". There ar...

It was Louis Pasteur who discovered that tartaric acid in the dextrorotatory (rotates polarized light to the right) form was present in ripening grapes. He found that certain chemical reactions racemized the tartaric acid.

Crick who discovered DNA and its functions with Watson propounded a classic dogma that one can go to proteins via RNA from DNA, but the return path from protein to nucleic acids is forbidden and not traversable.

Details of two kinds of recently discovered isomerism in organocobalt derivatives of vitamin B-12 will be studied. ... The second type of isomerism involves formation of pairs of apparently isomeric alkylcobalt derivatives when aquocobalamin is reductively alkylated with alkoxyethyl bromides. These cannot be alpha and...

The first true case of nuclear isomerism was discovered by Hahn in 1921. However, the only known example of nuclear isomerism that was available for a very long time (234Pa) had an extremely complicated level and transition scheme, which meant that it was impossible to establish the essence of the phenomenon.
