    The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

    Abstract The aim of the experiment is to test the existence of macromolecules which are carbohydrates‚ lipids‚ nucleic acids and proteins in given samples. The first experiment is to test the existence of carbohydrates in starch suspension and potato cell. If carbohydrate is present in starch suspension‚ the solution will turn into dark blue when iodine solution is added. If carbohydrate is present in potato cell‚ starch granules can be seen clearly under microscope when iodine solution is added

    Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed. ABSTRACT

    Identification of Macromolecules Introduction The most common macromolecules found in living organisms are lipids‚ carbohydrates‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain

    indicator. If the product of food contained the macromolecule that was tested for it would of showed if there was any difference from the two test tubes. The results of the lab seemed mostly reasonable. The only result that didn’t seem right was the cheese. Cheese is a dairy product which contains proteins however‚ the Big Macs cheese didn’t have proteins. Other than that the lab results looked right. The food product would match up with the correct macromolecule.

    ENERGY RESERVES OF MACROMOLECULES SUMMARY This experiment was conducted in order to show the energy received from the food that humans eat on a daily basis. The energy that is required by the human body to perform chemical reactions is obtained from the chemical bonds that formed between the atoms in the molecules. To calculate the amount energy‚ types of food products were burned underneath a test-tube filled with water. The temperature rise gave an estimate of the energy released per gram.
