The Uses of enzymes in industry and medicine Enzymes are Biological catalysts which allow the chemical reactions of metabolism to take place so therefore controlling the speed of the reaction. They are found in all living cells and are divided into two main groups, intracellular and extra cellular. Intracellular are found and work inside the cells, therefore are secreted inside the cell membrane, from where they control metabolism. Enzymes are complex globular proteins. Their long peptide chains of amino acids linked by peptide bonds are wound, folded and bonded into a precise 3D structure, owing their activity to this particular shape. They are compounds of high molecular weight. Enzymes are truly amazing molecules as they are used within industry and medicinal purposes as they are thermostable as they can work at high and low temperatures in contrast to catalysts which can only work at high temperatures as this is very useful...
