(Phys.org)—There are many naturally-occurring supermolecular structures. Among them are catenanes. From the Latin for "chain", a catenane is comprised of two interlocked molecules, and have been found in the mitochondrial ...
(Phys.org)—A team of researchers working in France has detected the presence of aldehydes in ice samples in their lab which were created to simulate material found in interstellar molecular clouds. In their paper published ...
Biologists claim that humans can perceive and distinguish a trillion different odors, but little is known about the underlying chemical processes involved. Biochemists at The City College of New York have found an unexpected ...

(Phys.org) —A new study by chemists in Switzerland is likely to change the way many stereoisomer molecules are synthesized for industrial, agricultural, or medical uses.
More than one-quarter of all known pharmaceuticals contain the chemical group known as amides: carboxylic acid derivatives derived from ammonia or amines. Most methods for synthesizing amides, however, are inefficient and ...
