Jennifer Moya Bio 124 Fall 2009 Introduction  This lab was done to to help us understand the techniques used in the analysis of  biologically important macromolecules and to start to understand some of their physical  and chemical properties.  Each group was given a food substance to test for glucose,  starch, lipids, and protein. My groups food substance was fruit juice. Our hypothesis was  that the fruit juice probably contained sugar and starch but not proteins  and lipids. We  picked this hypothesis because it was testable and thought it would likely be true.   I  predicted that the juice would test positive in the Benedict's test and the starch test  because, I thought that juice probably contained glucose because it is sweet and starch  because it has a lot of different ingredients that might contain starch. It is important to  be able to detect the presence of glucose because people with diabetes secrete it  through their urine (Crouch, Berger 2004) .   I have read the back of a juice carton  before and know there are a lot of different ingredients. However, I didn't think that it  would contain lipids or proteins because lipids do not dissolve in water, and protein is  found in stuff like eggs and meat.  Material and Methods
