(Phys.org)—During brewing, beer obtains its bitter flavor from the bitter acids that come from hops. In the journal Angewandte Chemie, scientists now report that they have used X-ray crystallography to determine the absolute configurations of these humulones and isohumulones, as well as several of their derivatives.
