SHORT NOTE ON ENZYME
ENZYMES Enzymes are- 1)colloidal,thermolabile;protein in nature. 2)Synthesized by living cells. 3)They may catalyze thermodynamically either inside or outside the cell. Substrate: Substances on which enzymes act to convert them into product are called substrate. E+ [S] ---------> [ES]------>E + P <--------- ****** 1) Coenzyme: Non protein, Organic substance; EX:NAD+ 2) PROSTHETIC GROUP: Non protein, Non dialysable Ex:FAD+ 3) CO FACTOR: Non protein, either organic or inorganic. It is two types:----- 1)Metal-activated enzymes Ex:Na+, ca++ 2)Metalloenzyme Ex:Mn, Mo _____________________________________________ **Classification of coenzyme 1) First group of coenzyme 2) Second group of coenzyme _____________________________________________ The protein part of the enzyme is called apoenzyme.It is heatlabile. ________________________________ HOLO ENZYME: The complete structure of apoenzyme and prosthetic gr
