What Are Organic Catalysts?

Organic catalysts are simply the enzymes. These, in a dry technology nutshell are the biocatalystically-active proteins with a high molecular mass and complex structure.   
Enzymes are fairly large molecules, at least biochemist's viewpoint. Just one example for the size, if the enzyme trypsin, one of the first enzymes to be investigated at the start of enzymemological science, were magnified to be ten centimeters in the size it would stretch to a fantastic length. For comparison, a man enlarged to the same extent would be 40000 kilometers tall and would be able to wrap himself around the whole equator.

As can be seen and enzyme is not a universal genius but a rather one sided specialist. A biochemist would say that each enzyme is substrate – specific or almost. There are the exceptions to every role but all in all, it is not very far from the truth to say that each enzyme type is only able to take up and alter one specific species of substrates in its precisely shaped active site.

Each enzyme is also reaction specific. This means that it can only carry out one quit specific change on the substrate, producing one single effect.
