Testing for Complex sugars - the lodine test

We are doing some testing for complex sugar to see if its protein, complex or simple. I put all the work what we have done on my blog.




Aim:  To see if different food has simple sugars, complex sugars or protein in.       



Hypothesis:    
Apple, I think its protein.
Bread,  I think its complex.
Potato, I think its complex.
Egg,  I think its protein.
Milk, I think It's simple.

 Bread: Complex

Equipment: Test tube, food sample, iodine solution.


Method: 1. place about 2 ml of the sample in a test tube.

          
                             2. Add 3-5 drops of iodine and mix


Result:

Apple and egg there both protein, bread and potato they also both complex and there is the only 1 is simple is the milk.



Conclusion:

This is our first testing for complex sugars, I have 1 friend that is in my group we work together to do this testing and I think we've done very well.
