Enzymes are biocatalysts, organic plant, animal and microorganism has a catalyticability (the vast majority of proteins. But a small amount of RNA also has abiological catalysis), formerly known as enzyme. Chemical reactions of the bodyalmost all in under the catalysis of enzyme. The enzyme catalysis has a selectivity.
For example, starch. Enzymes that catalyze the hydrolysis of starch into dextrin and maltose, protease catalyzed hydrolysis of proteins into peptides. Living organismsuse them to accelerate the chemical reactions in the body. Without the enzyme,many chemical reactions in living organisms will be slow, difficult to sustain life. At about 37 ℃ temperature (body temperature), enzyme working condition is the best.
If the temperature is higher than 50 ℃ or 60 ℃, enzyme will be destroyed and can no longer function. Therefore, using biological detergent enzymes to break downstains on clothing, the use of the most efficient at low temperature. Enzyme inphysiology, medicine, agriculture, industry and so on, are of great significance.
At present, the application of enzyme preparation is more widely. (for example:enzyme as a catalyst used in industry, some enzyme or precious medicine. )
In the chemical production, the scientists experiment and life of the catalyst, display one's skill to the full. For example, in the production of sulfuric acid with five of two vanadium catalyst. Nitrogen and hydrogen in ammonia, with multiple packet with iron based catalyst, increase the rate of reaction.
In the refinery, the catalyst is ultimately, choose different catalysts, we can get different quality of gasoline, kerosene.
Chemical synthesis of acidic and basic color Seth catalyst. Carbon monoxide and nitric oxide harmful vehicle exhaust, using platinum as a catalyst can be quicklyconverted to carbon dioxide and two nitrogen harmless. Enzyme is a plant, animaland microbial protein with catalytic ability, chemical reaction, almost all theorganisms in under the catalysis of enzyme, brewing industry, the pharmaceutical industry will be used as the catalyst.
