Enzyme Behavior Emulated By Synthetic Molecules For The First Time

Categorie : Biology / Biochemistry
When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly specialized catalysts, and finding one in just the right shape to connect with certain molecules can be difficult. Na ...
