LAB: Macromolecule Testing
One characteristic of life is that living things are made up of molecules containing carbon. These are called ORGANIC MOLECULES. In our class we have been referring to them as macromolecules since they are necessary for life. The most common organic compounds found in living organisms are LIPIDS, CARBOHYDRATES, PROTEINS, and NUCLEIC ACIDS. Common foods, which often consist of plant materials or substances derived from animals, are also combinations of these organic compounds. Simple chemical tests with substances called indicators can be conducted to determine the presence of organic compounds. A color change of an indicator is usually a positive test for the presence of an organic compound.
PURPOSE:
To use indicators to test for the presence of lipids, carbohydrates, and proteins in various foods.

# Macromolecule Lab Report
**Name:** [Your Name]
**Date:** [Date]
## Introduction
Macromolecules are large, complex molecules that are essential for life, classified into four major categories: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are composed of sugar molecules and serve as a primary energy source for living organisms. They can be classified into simple sugars, like glucose and fructose, and complex carbohydrates, such as starch and glycogen. Lipids, which are hydrophobic molecules, include fats, oils, and phospholipids; they are crucial for long-term energy storage, insulating and protecting organs, and forming cell membranes. Proteins are made up of amino acids and play a significant role in building and repairing tissues, making enzymes, and regulating bodily functions. Lastly, nucleic acids, like DNA and RNA, are responsible for storing and transmitting genetic information.
In this lab, five different substances were tested for the presence of macromolecules: water, oil, milk, corn starch, and eggs. Water is a universal solvent and does not contain significant macromolecules. Oil, primarily consisting of fats, is a source of lipids. Milk is a complex mixture rich in carbohydrates, proteins, and some fats. Corn starch is a polysaccharide primarily made of carbohydrates. Eggs contain proteins and some lipids and also contain small amounts of carbohydrates. The results of these tests indicate the presence or absence of these macromolecules in each substance through specific color changes with indicators.
## Hypothesis
1. If we test water for macromolecules, it will test **negative for all tests**.
2. If we test oil for macromolecules, it will test **positive for lipids**.
3. If we test milk for macromolecules, it will test **positive for carbohydrates** and **proteins**.
4. If we test corn starch for macromolecules, it will test **positive for carbohydrates** (starch).
5. If we test eggs for macromolecules, it will test **positive for proteins** and **lipids**.
## Purpose
To use indicators to test for the presence of lipids, carbohydrates, and proteins in various foods.
## Safety
Goggles and gloves should be worn during the experiment. Biuret reagent can cause burns, hence careful handling is required.
## Procedure
**See lab sheet for detailed procedure.**
1. Testing for lipids involved applying food samples onto a piece of paper towel and observing for grease stains.
2. The carbohydrates were tested for starch using iodine solution and for sugars using glucose test strips.
3. Proteins were tested using Biuret reagent, observing any resulting color change.
## Data Table
| Substance | Lipid Tests (1 test) | Carbohydrate Tests (2 tests) | Protein Test (1) |
|------------|-----------------------|-------------------------------|-------------------|
| | Spot or No Spot (Lipid Present +) | Test Strip Color (Sugar Present +) | Iodine Color (Starch Present +) | Biuret Color (Protein Present +) |
| Water | No Spot | Yellow | Brown | No change |
| Oil | Spot | Yellow | Brown | No change |
| Milk | No Spot | Green | Light Purple | Positive |
| Corn Starch| No Spot | Yellow | Brown | No change |
| Eggs | Spot | Yellow | Brown | Light Purple |
| Mystery | [Results Pending] | [Results Pending] | [Results Pending] |
## Results
1. **Which test substances contained LIPIDS?**
Oil and eggs tested positive for lipids.
2. **Which test substances contained STARCH?**
Corn starch tested positive for starch.
3. **Which test substances contained SUGAR?**
Milk tested positive for sugars.
4. **Which test substances contained PROTEIN?**
Milk and eggs tested positive for proteins.
5. **Which test substances did not test positive for ANY organic compounds?**
Water and oil (in terms of proteins and carbohydrates) did not test positive for any organic compounds.
## Conclusion
I accept my hypothesis for the tests performed on milk, oil, and eggs, as my predictions for these substances were accurate. Water did not contain any macromolecules, while oil contained lipids. Milk was confirmed to contain both carbohydrates and proteins. The mystery substance was yet to be determined, but further tests would reveal its macromolecular composition. By observing the color changes with the respective indicators and matches to known reagents, I can affirm the presence or absence of each macromolecule in the tested substances. The results highlight the biochemical diversity of the selected substances and their roles in biological processes.
