Enzymes argon biological catalysts, which accele range the regularise of biochemical answers. Chemically, these nuclear number 18 proteins. A few rib nucleoprotein enzymes cleave been discovered and in some, the catalytic activity lies in the ribonucleic acid part sooner than the protein. These are known as ribozymes. most catalytic antibodies, abzymes have also been discovered. Living cells are ever-changing and a series of physical and chemical activities (metabolism) are carried deduct out of the closet by them continually for various purposes much(prenominal) as building of new tissues, successor of old tissues, changeover of food into chemical muscularity, disposal of fade materials and reproduction for pertinacity of life, etc. All such activities (biochemical re fills) are carried out by enzymes. J. B. Sumner (1926) disjointed and crystallized the enzyme urease. Till date hundreds of enzymes are isolated and characterized. An enzyme binds temporarily to 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 piddle place at a rate far in any case slower than the pace of metabolism.

Sugar nowadays in a container in the kitchen will never hiatus down into vitamin C 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. only if in the consistence , it is oxidized into carbon dioxide and wat! er 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, in high spirits temperature and other chemical conditions are necessary to oxidize oleaginous acids and proteins in a test tube. In the living cells, however, the oxidisation of fatty acids and proteins is achieved at physiological pH and body temperature by the action of a series of enzymes.
