Sprite And Muscle Milk Lab Report

Introduction

In this lab, we were assigned to investigate the question of what types of macromolecules are in both Sprite and Muscle Milk to give us an idea of what we are taking into our bodies. Those macromolecules we tested for consisted of Protein, Glucose, Start, Vitamin C, table salt or NaCl, and triglycerides. We are able to identify the different macromolecules by comparing the sprite or muscle milk with the added solution which indicates the presence of macromolecules, to the control group. We would then be able to see if the substances were tested positive or negative in containing certain macromolecules. It is very important to have both positive and negative control groups in your experiment to compare each possible outcome too.

At each station, there are four graduated cylinders, two of which acted as control groups, and two for the two spritesand muscle milk. You would put drops of the solution, that identifies if a certain macromolecules are present varying on each station, into each of the control groups. The control groups were a substance that contains the macromolecule which is being tested for and a substance that does not. You would then compare the sprite and muscle milk that you added the solution to, after stirring each graduated cylinder, and see which control group it represents most

Our original hypotheses that were correct for Sprite were protein, glucose, starch, Vitamin C, salt and lipids. For Muscle Milk, the ones that were correct were protein, glucose, starch. There were no hypotheses for Sprite that were disproven by the tests, but for Muscle Milk Vitamin C, lipids and salt were all incorrect. For our protein hypotheses, we thought Sprite would not contain it, because protein is not in water, sugar or the carbonation, which is basically what makes up soda. We were proved correct by the tests. For Muscle Milk, we predicted that it would contain some protein, because muscle milk is used for muscle gains, which is proteins. After testing, the tests proved that Muscle Milk has protein in it. For the glucose tests, we predicted that Sprite would contain glucose in it due to its sugary taste. As well, it gives a quick boost of energy, rather than a sustained one. And for Muscle Milk, we predicted that it would contain glucose in it to make the taste more appetizing. The tests showed that they both have glucose in it. For the starch hypotheses, we predicted Sprite doesn’t have any starches, because, as stated before, it doesn’t give sustained energy, just a quick boost, and Muscle Milk does have starches in it, because it gives sustained energy. We were proven correct for both by the tests by the tests. For our Sodium Chloride tests we were proven correct for Sprite. We predicted
