joined together; Bio and Catalysis. “Bio” prefix denotes biological and “catalysis” means the acceleration of a chemical reaction due to a catalyst. So in general biocatalysis is the use of biological (natural) catalysts, such as enzymes. These biological catalysts are used to transform organic compounds chemically. An enzyme is a protein catalyst that is responsible for the reactions in your body. Enzymes help with digestion of food, production of essential nutrients, movement of muscles, etcetera.

Polymers are additives used widely in pharmaceutical systems for numerous objectives, i.e. as suspending, emulsifying and flocculating agents, adhesives, and for packaging and coating materials. Polymers are made up of repeating monomer units with a high molecular weight. Their chemical reactivity depends on the chemistry of their monomer units, but their properties depend mainly on how the monomers are assembled together. Nearly all polymers exist with a range of molecular weight and for convenience

mixture of Iron and Molybdenum oxides as the catalyst, the formation of Formaldehyde occurs through the following chemical reaction CH3OH + ½ O2 → HCHO + H2O On the other hand when you use silver metal as the catalyst, the formation of Formaldehyde is governed by two simultaneous reactions. One of them is the one you see above while the other one is a dehydrogenation reaction. CH3OH → HCHO + H2 The mechanism shown above clearly illustrates this. So, when you use Silver metal as the catalyst, you obtain
