(Phys.org)—A gigantic number of chemical reactions take place inside our bodies every second, all synchronizing with each other to produce the energy and chemical compounds that we need to survive. Together these reactions ...
One of the first reaction mechanisms students learn in undergraduate organic chemistry is the SN2 reaction. Named because it involves the collision of two molecules, its energy barrier is related to the nucleophile, the solvent, ...
Enzymes are naturally existing biocatalysts of great potential for application in sustainable chemistry. Yet, controlling enzyme reactions at atomic level is still a challenge in biology. Scientists at the Max Planck Institute ...
