Egg Macromolecules Lab

In this egg lab we asked the question, "Can macromolecules be identified in an egg cell?"
In the egg membrane, we identified macromolecule that could be found. One of the macromolecules we found was protein. We know there was protein because the egg membrane turned light purple. We also learned in class that proteins are in cell membranes because they let things in and out of the cell. This evidence supports the claim that a macromolecule could be identified because we identified protein when the membrane turned light purple, and because of the information we learned in class.
In an egg white, we also identified a macromolecule. We found lipids. We know there were lipids because the egg white turned to a bright orange. In class, we learned lipids are in the cytoplasm, or egg white, of the cell, because lipids hold a lot of energy and are also in mitochondria, which are also in the cytoplasm, or egg white, of the cell. This evidence supports our claim because we identified lipids when the egg white turned bright orange, and because of the information we learned in class.
In the egg yolk, we identified monosaccharides. We know there were monosaccharides because the egg yolk turned from blue to green. We also learned in class that monosaccharides are in the cell nucleus, or egg yolk, because the chain of monosaccharides allows the nucleus to receive energy and get rid of waste. This evidence supports our claim because we identified monosaccharides in the egg yolk when the yolk turned from blue to green, and because of the information we learned in class.
One possible error we had was that when we were putting the egg yolk in a beaker, we accidentally put some egg white in there with it. This could have effected our data because when we were testing the egg yolk for certain macromolecules, we could have found certain macromolecules that are only in the egg white and thought it was in the egg yolk, too.
A second possible error we made was not cleaning the cell membrane. When we tested it, the membrane still had egg white on it. This could have effected our data because when we were testing the egg membrane for certain macromolecules, we could have found certain macromolecules that are only in the egg white and thought it was in the egg membrane, too. Two possible fixes for these problems are to be more careful while pouring the egg yolk into a beaker, and to clean the egg membrane.
The purpose of this lab was to find which macromolecules were in which parts of the cell. This relates to what we learned in class because we learned a lot about what macromolecule was in each part of the cell. This information could be used in other ways that finding out what macromolecules were in the egg. We could use this data to find out what other macromolecules are in other foods we ate, how much of the macromolecule is in the food, and to create a better diet.
