In this lab, we tried finding out if macromolecules could be identified in an egg cell. For the negative control, which was water, the egg cell was identified in the monosacharide and lipid, and was not identified in Polysacharide and Protein. For the egg membrane, it was tested positive in Monosacharide, lipids, and Polysacharide, and tested negative in the Protein. With the egg yolk, the egg cell was present in all four macromolecules. And finally for the egg white, the egg cell was in the Proteins and lipids.
During the lab, when the egg white turned black from the Protein and Lipids and monosacharides, this is because of the fact that both macromolecules are used in the egg white for development of enzymes in the egg white and because the lipids give off energy to the egg white. The egg membrane contained Polysacharides and lipids, since they turned black or orange when tested. This is because of the fact that lipids make up the membrane, and it stores energy for the membrane. When we tested the egg yolk, all four macromolecules were all present. This is because lipids are in the membrane, proteins are the building blocks for the baby in the yolk, and the mono polysacharides give off energy.
An error we had was at the end of the experiment we gave each other the wrong data because we thought someone else was doing monosacharides when he was actually doing polysacharides, and it was messed up. Something we could do to fix that is just to be careful about the information we share and make sure that if we had been writing down the information, that we wrote it in the corresponding box.
Other than that, we didn't have any big mistakes, but a hypothetical mistake that we saw a lot of other groups do was when they sifted out the yolk from the white , the yolk didn't cooperate and wouldn't sift out. To prevent that, our group was very careful about that and I should that other groups should have just been more careful. TWO big helpful pieces of advice would be to be careful and know your own strengths, especially in a lab like the egg lab, were you are dealing with fragile things. Just be careful and make sure you don't break anything.
The purpose of this lab was to test the four big macromolecules to see if they were in any parts of an egg. We did just that and found that there are some macromolecules in the egg. This relates to the macromolecules vodcast that we did a few days ago, and it talked just about this and how the four macromolecules worked. I think the purpose of that vodcast was to get us ready for the lab. This can be applied to situations that I can't think of right now, and I probably won't know because I don't really care about the egg industry. But I learned a lot about eggs, like they are very fragile. I'm just running out of things to say, so that's all.
