Heterogeneous catalysis, in which the catalyst and reactants occupy separate phases, is something of a black art when compared with homogeneous catalysis .
In either case, the new structure represents an interesting and unique case of metal coordination in enzyme catalysis .
In general, chemical catalysis offers faster reactions times than bioremediation schemes but also tends to be more expensive.
After polymerisation using heat, light, radiation or catalysis , a range of strong thermosetting plastics can be produced.
The partial negative charge on the oxygen atom makes it susceptible to acid catalysis .
Liposomes are widely used as models of biomembranes and in applications such as solar energy conversion, chemical catalysis , and drug delivery.
Enzymes have been widely praised for their specificity and efficiency in stereospecific catalysis .
Histidines are often involved in acid base catalysis , and prone to activate nucleophiles by abstracting a proton.
Thus, catalysis is believed to involve a one-step, metal-ion-mediated hydrolysis of the substrate by a metal-activated water molecule.
Interestingly, protein loops are often involved in protein activities, including ligand binding and catalysis .
