Benedict's reagent
They test for carbohydrates. The Iodine reagent tests for starch. The Benedict's reagent tests for small sugars. Most carbohydrates are are made of sugar, and starch is a type of carbohydrate.
Presence of starch. Polymers of reducing sugars.It's used to test for the presence of glucose in a patients urine - a standard test for diabetes.starchBenedict's reagent is used as a test for the presence of all monosaccharides, and generally also reducing sugars. These include glucose, galactose, mannose, lactose and maltose. Even more generally, Benedict's test will detect the presence of aldehydes (except aromatic ones), and alpha-hydroxy-ketones, including those that occur in certain ketoses. - wikipedia
This reagent is bromine in solution.
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
Starch is energy for our body, glucose can not be stored so it is stored as starch, but before this starch can be used as energy to our body, it must be turned back into glucose, this is done by amylase, it breaks down the starch back into glucose so it can be used.
The reagent that is used to test for starch is a mixture of iodine and potassium iodide in water, or an Iodine - KI reagent. If the reagent turns blue-black in color, then starch is present.

The presence of starch can be tested with the help of Iodine. Similarly Benedict's test solution is also used to detect the presence of starch.
This reagent is bromine in solution.

You are not supposed to use buret reagent to detect sugar carbohydrates in a solution. Buret reagent is used to detect proteins. Try using iodine ( I2KI)
Starchput a drop of iodine in suspected starch stuff and if it changes colour from red to black/purple it has starch in !!!!!!!!!!!!!Fatrub suspected fatty stuff on brown paper and if it has a translucent spot were you rubbed there is fat in your substance!
Because glucose is used for growth
Plants convert unused glucose into 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.
