              Enzymatic Hydrolysis of starch:



              -Amylase: “Endo-amylase”


                       It is an enzyme present in pancreatic juice and saliva It hydrolyses starch

              by a random splitting of   -1, 4 glucosidic linkages leading to:












                                              -Amylase = [1,4-Linkage Endoamylase]
