Enzymes argon biological catalysts, which accele range the treasure of biochemical answers. Chemically, these nuclear number 18 proteins. A few rib nucleoprotein enzymes have been discovered and in some, the catalytic activity lies in the ribonucleic acid part sooner than the protein. These are known as ribozymes. or so catalytic antibodies, abzymes have also been discovered. Living cells are gamy-powered and a series of physical and chemical activities (metabolism) are carried father out of the closet by them continually for various purposes much(prenominal) as building of new tissues, successor of old tissues, alteration of food into chemical cleverness, disposal of fade materials and reproduction for tenacity of life, etc. All such activities (biochemical re achievements) are carried out by enzymes. J. B. Sumner (1926) isolated and crystallized the enzyme urease. Till date hundreds of enzymes are isolated and characterized. An enzyme binds temporarily t o one or more substrates / reactants of the reaction it catalyzes. It accelerates the rate of a biochemical reaction by great(p) the activation energy needed to carry out the reaction without the enzyme (Without the enzyme the reaction would dispatch place at a rate far to a fault slower than the pace of metabolism.

Sugar nowadays in a container in the kitchen will never hiatus down into ascorbic acid dioxide and piddle, if it is stored at the room temperature. It breaks down into carbon dioxide and water by reacting with the atmospheric oxygen, only when we burn or oxidize it. plainly in the consiste nce, it is oxidized into carbon dioxide and ! water by the action of a series of enzymes at the body temperature. In this process, it releases energy, which is utilize by the body. Same is the case for dipper acids and proteins. Extreme pH, high temperature and other chemical conditions are necessary to oxidize oleaginous acids and proteins in a test tube. In the living cells, however, the oxidation of fatty acids and proteins is achieved at physiological pH and body temperature by the action of a series of enzymes.
