Bond-selective reaction is central to heterogeneous catalysis. In heterogeneous catalysis, selectivity is found to depend on the chemical nature and morphology of the substrate. Here, however ...

Researchers from the University of Adelaide have discovered how water molecules are organized during plant hydrolytic ...

More specifically, they lower the threshold necessary to start the intended reaction. They do this by binding to another substance known as a substrate. The “lock and key” model was first ...

This is essential to the enzyme being able to work. One enzyme is therefore specific to one substrate's chemical reaction, or type of chemical reaction. The human body is maintained at 37°C as ...

Well, nearly all plant tissues contain PPO, however, the level of PPO activity and concentration of substrate--here ... and thus slow the browning reaction. Lemon or pineapple juices, both ...

The enzymes change the substrate at each step in the metabolic ... An example of an anabolic reaction is photosynthesis, where plants make glucose molecules from different raw materials.
