BIO QUESTIONS (from Tau blog. Thanks, Tau :D)

1. Summarize your results as to what biomolecule are present in the different samples including the food item you brought. Were the results similar to what you expected based on the ingredients of the different materials?
2. Discuss whatever errors committed or difficulties encountered in the tests and the factors that contributed to these.
3. Compare expected and observed results for your food item and milk based on their composition.

Research on some of the tests used in determining the presence of carbohydrates, lipids, and proteins. You may want to explain the color changes and reactions observed in the different tests. Do not forget to cite your references within the discussion with accompanying bibliographical entries at the end of your write-up.
