Chemistry Nobel Explains Molecular Mirror Mystery, Revolutionizing Medicine

Why do living organisms almost always use just one version of certain molecules, while the mirror-image version is largely absent from nature? This question puzzled scientists for over a century. This year's Nobel Prize in Chemistry honors two researchers whose work helped solve this mystery and opened new avenues for developing safer, more effective medicines. The discovery centers on chirality—the property of molecules that exist in two mirror-image forms. Understanding why biology prefers one form has profound implications for drug design, as the wrong mirror image can be ineffective or even harmful. This DW News report breaks down the science behind the award and its potential to transform pharmaceutical development. The chapter breakdown includes an introduction to the Nobel Prize and an explanation of molecular mirror images.
