Biological catalyst

Your body depends on reactions that are catalyzed by amazingly efficient and specific biological catalysts. Biological catalysts are enormous protein molecules called enzymes. Their molecular masses range from 15 000 to 1 000 000 g/mol. 

C. Laboratory reactions are uncatalyzed, or use simple catalysts biological reactions are enzyme-catalyzed.

The hydrolysis of glycylglycine, however, is extremely rapid in the presence of a catalyst. Biological catalysts are called enzymes. In this case the enzyme is a large protein containing a Co + ion that can bond to six atoms (an octahedral arrangement).

Thousands of chanical reactions are taking place constantly in our body. Without catalysts, these chemical reactions would not be fast enough for our body to function properly. Virtually all the chemical reactions in Uving oiganisms are dependent on catalysts. Biological catalysts have a special name enzyme(s). They are andal for biological functions. Enzymes are one of the most studied groups of substances today. 

An important aspect for materials with applications in the biomedical field is the use of nontoxic catalysts. Biologically nontoxic magnesium and calcium complexes have been successfully employed for the ROP of TMC however, the toxicity of the salen ligands has not been assessed, and polymerization... 

The chemical industry could not function without catalysts as they enable reactions to occur at economically viable rates. They also enable some reactions to occur which in their absence would not occur at all. Catalysts are used to refine fuels, thus enabling transport. They are used in the manufacture of polymers, thus enabling the fabrication of so many of the artefacts of everyday life as well as the fabrics of fashion and furnishings. Without catalysts there would be very little of what we recognize as the familiar modern world. Our bodies also function under the control of catalysts. Biological catalysts are called enzymes, and I describe their function in Reaction 27.
