The question of this lab was "Can macromolecules be identified in an egg cell?"
Macromolecules could mostly be identified in egg yolk. In the egg yolk, for the Monosaccharide, Polysaccharide, and Protein test, the macromolecule was present. In the Lipid test, the macromolecule wasn't present, having the quantitative amount of macromolecule of 0 and not changing colors. In the Monosaccharide test, the egg yolk had a quantitative amount of macromolecule of 5, turning slightly purple. In the Polysaccharide test, the egg yolk had a quantitative amount of 4, turning light brown. In the Protein test, the egg yolk had a quantitative amount of 7, turning a bit clear. These evidences support my claim because the quantitative amount and the colors that the egg parts changed to show that the macromolecule was/wasn't present.
Macromolecules can be identified in the egg membrane. In the egg membrane, for the Monosaccharide, Polysaccharide, Protein, and Lipid test, the macromolecule was present. In the Monosaccharide test, the egg membrane had a quantitative amount of macromolecules of 8, turning purple. In the Polysaccharide test, the egg membrane had a quantitative amount of macromolecule of 6, turning brown. In the Protein test, the egg membrane had a quantitative amount of 5, turning light purple. In the Lipid test, the egg membrane had a quantitative amount of 3, turning pinkish. These evidences support my claim because the quantitative amount and the colors that the egg parts changed to show that the macromolecule was/wasn't present.
Macromolecules can be identified in the egg whites. In the egg whites, for the Monosaccharide, Polysaccharide, Protein, and Lipid test, the macromolecules were present. In the Monosaccharide test, the egg white had a quantitative amount of macromolecule of 3, turning blue. In the Polysaccharide test, the egg white had a quantitative amount of macromolecule of 5, turning dark brown. In the Protein test, the egg white had a quantitative amount of 6, turning purple. In the Lipid test, the egg white had a quantitative amount of 5, turning pinkish. These evidences support my claim because the quantitative amount and the colors that the egg parts changed to show that the macromolecule was/wasn't present.
One error that could've occurred in this lab were that some of my group members could've put in less drops then what was required for the egg part. This could've affected the results by not allowing the macromolecules a chance to appear in the egg part. A second error could've been the accuracy of the quantitative amount of macromolecules. Since the quantitative amount of macromolecule was completely based off a person's opinion, it can't be the most accurate. This would affect the results by making them not entirely true or false.
A way to improve the experimental procedure so that errors could be minimized or removed are to always be careful with any solution you might be handling and to constantly interact with your group members throughout the lab.
The purpose of this lab was to see if macromolecules can be identified in an egg cell. In this lab we tested the different egg parts for the certain macromolecule we were looking for. Before this lab, we had already gone through the different type of macromolecules. We also learned beforehand what to use in order to test for its presence and how to know if it's present.
This lab experiment could be applied to other experiments by applying where macromolecules are, how to find them, and how to know when they're there.
