for the starch iodine test is performed in which the starch reacts with iodine to produce dark blue colour which confirms the presence of starch.
for glucose benedict's and fehling's test is performed.
benedict's test: 1 ml sample is mixed with 1 ml of benedicts solution and the heated upto boiling if the colur changes to brick red then it confirms the presence of glucose
fehling's test: similarly 1 ml fehling's solution I & fehling's solution II each in taken together and to it 1 ml of the sample is takenon then heated uptill boiling. if the colour changes to brick red the it confirms the presence of glucose.

If it contains starch then it will turn blue, black What colour dose the tests turn in the presence of starch? For the starch iodine test is performed in which the starch reacts with iodine to produce dark blue colour which confirms the presence of starch. for glucose benedict's and fehling's test is performed. benedict's test: 1 ml sample is mixed with 1 ml of benedicts solution and the heated upto boiling if the colur changes to brick red then it confirms the presence of glucose fehling's test: similarly 1 ml fehling's solution I & fehling's solution II each in taken together and to it 1 ml of the sample is takenon then heated uptill boiling. if the colour changes to brick red the it confirms the presence of glucose. Where is the enzyme found in the body? The enzyme breaks down starch into glucose? Like all enzymes, amylase is a catalyst, so it only speeds up reactions which would happen anyway. However, without the enzyme many reactions would be extremely slow. So starch could break down into glucose in the absence of amylase (provided water was present), but only very slowly.
