Nobel Prize in Chemistry for the three chemical waves Click bioorthogonal chemistry to improve the precision of medicines

  • No comments
The Nobel Prize in Chemistry for 2022 was awarded to three scientists working in the field of synthetic chemistry: Caroline Bertuzzi (Carolyn R. Bertozzi), Morten P. Meldal (Morten P. Meldal) as well as Karl Barry Sharpless (KarlBarrySharpless), thanks to "the development of 'click' chemistry and bio-orthogonal chemistry". This is Sharples' second win in chemistry - the previous one was in 2001
Figure 3. Pabo's discoveries provided important information regarding the population of the world at the time Homo sapiens migrated out of Africa and spread to the rest of the world. Neanderthals lived in western Eurasia while Denisovans lived in eastern Eurasia. Breeding between the different species occurred when the Homo sapiens spread across the continent, leaving behind treasured remains in DNA.
