Carbohydrate ID lab



In the Carbohydrate ID Lab we used Starch Flour Glucose and a Pop-tart, as well as a boiler. We mixed all these substances with Iodine or Benedict. Iodine is a dark blackish brownish color and benedict is a blue color. Mixing these two substance with any of the other substances determined what we created. Some we Boiled and some we didn't.  In the lab results you can see what ones we boiled and what ones we didn't.


Lab Results

Iodine + Starch =  Poly
   When we mixed these two together We came out with poly. It didn't do Nothing just turned black when we added the iodine

Starch + Benedict = poly     Boiled
   When we added starch and benedict and boiled it we still came out with another poly. Nothing changed just that it turned black.

Flour + Benedict = poly       Boiled
     When we added Flour and benedict and boiled it we came out with again another poly. No change just turned black

Flour + Iodine = Poly
     When we added flour and Iodine with no boil it still came out to be a poly.

Glucose + Benedict = Mono    Boiled
    When we added Glucose and benedict and boiled it we got a change it turned orange and became a  
    Mono.

Flour is mostly Poly 

Pop Tart + Benedict = Poly    Boiled
      Even with pieces of food with Benedict turned into Poly.

From doing this lab We have learned that all Carbohydrate have monosaccharides and sometimes put together in BIGGER chains to make Polysaccharides.
