Feeding Frenzy food lab

Introduction (5 points)

Purpose (1 point)
The purpose of this experiment is to determine what macromolecules are in the four different foods

Question (1 point)
What macromolecules are in buttermilk biscuits, potato chips, hot peppers, and sardines?

Background (1 point)
Macromolecules are molecules with a large number of atoms. There are four types of macromolecules: carbohydrates, proteins, lipids and nucleic acids. In this lab we will test four foods to see if they contain carbohydrates
(sugar and/or starches), proteins and lipids. We will use chemical reagents to test to determine the presence of macromolecules: Benidicts solution for sugar, Iodine for starch, Biurets reagent for protein, and Sudan III for lipids.

Hypothesis (1 point)
If we test buttermilk biscuits for starches, sugars, proteins and lipids then it will test positive for all. If we test potato chips for starches, sugars, proteins and lipids it will then test positive for lipids and starch. If we test peppers for starches, sugars, proteins and lipids then it will test positive for only sugar. If we test sardins for starches, sugars, proteins and lipids then it will only test positive for proteins and lipids.
