Problem/question: What Macronutrients will coffee and chocapic have?
Hypothesis: To infer what Macronutrients chocapic and coffee have I must reflect on myprevious knowledge of the macro nutrients. From my previous knowledge I can say that glucose and sucrose give energy which one of them will probably be found in coffee. It is probable that chocapic will Ihave glucose or sucrose because it is sweet. Probably chocapic might have lipids because they have chocolate in them and that comes from milk which has lipids. Coffee probably doesn’t have lipids justbecause it doesn’t come from an animal product. Both coffee and chocapic might have starch since starch is found on grains; chocolate is generated from cocoa beans and coffee from coffee beans.Proteins give you energy therefore probably coffee has proteins and chocapic might give energy therefore there might be proteins in chocapic.
Material tested Test Name Initial color Final color Otherobstervations Test Results
yogurt Filter Paper Fat Test The paper looked wet with a little white residue on it Clear You could see through the filter paper Yogurt has lipids/fat
yogurt Benedicts Whitishblue with the benedicts On the top it was white, below a lime green color existed, and on the bottom it was orange. As the test tube sat in the boiling water some of the green turned to orange Yogurtcontains monosaccharide and disaccharide
yogurt Biuret White Purple The biuret solution turned purple as soon as it touched the yogurt Yogurt does have proteins.
yogurt Iodine White A black andbrown color existed There were black particles in the brown solution Yogurt has starch
Standard Sucrose Benedicts Clear blue A light green It took a few minutes for the colors to change Standard sucrosehas monosaccharides and disaccharides.
Standard Gelatin Biuret Light brown Purple The biuret solution turned purple immediately Standard Gelatin contains protein
Standard Corn Starch Iodine White...
