Where are the Macromolecules in an Egg?

In this lab we asked the question of what can macromolecules be identified in an egg cell. In the egg yolk, we hypothesized that if the yolk is the cell of the egg, then all macromolecules will be found in it. We hypothesized if lipids are in all membranes, then they will be in the egg membrane. Our hypothesis for the egg white was if egg whites are food for baby chicks, then protein will be in the egg white.

We found that the egg yolk had monosaccharides, polysaccharides, protein and lipids. It had a score of eight for monosaccharides with an orangey-yellow hue. For polysaccharides it scored five. Its color was a dark brown. We discovered that proteins have a smaller presence with a score of three. This time it was dark blue to black. The lipid test revealed a score of six with an orange tint.

In the egg membrane, we found every macromolecule, but only a small amount of monosaccharides and protein. For monosaccharides, it scored a mere two with a blue tint. In the polysaccharide test, it was brown, scoring six. It earned two points in the protein test where it was light purple. For lipids, it had a pinky-orange hue with a score of six.

The egg whites had an abundance of proteins but little monosaccharides and lipids and no polysaccharides. It earned a two in the monosaccharide test with a light blue shade. It scored zero in the polysaccharide test with a supporting orange tint. It was dark purple in the protein test, scoring a nine. It earned a three on the scale in the lipids test, with only the surface orange.

Our results generated colors expected from the tests. Healthyeating.sfgate.com explains that carbohydrates (monosaccharides and polysaccharides), proteins and lipids are all in the egg, supporting our results. However, it seems that we got too high of a presence of some carbohydrates and not enough lipids in the egg yolk. This data supports our hypotheses and mostly our results

While our hypotheses were supported by our data, there could have been errors because a different person conducted a different test. The significance of that is that the scale is objective. For example, a four for me could have been a six for my partner. Also, we didn't see other tests so our scale is relative to our test, without looking at the big picture. These problems make our tests not useful in knowing the amount of a macromolecule but simply if it's there. Due to these errors, in the future I recommend at least one person present for each test to help decide on a rating based on all the results. In addition, the results should all be seen before the ratings are given.

This lab was done to understand what macromolecules are in and egg and to relate the egg to any cell. From this lab I learned how vital the location of macromolecules are in order for the egg cell to have optimal success which helps me understand the importance of it for cells in general. This is applicable to any cell, but in the bigger picture, any group that's trying to get something done. In factories, they factory as a whole produce their product, but workers have different jobs and stations.

Candy Electrophoresis Lab

1. When you analyzed the results of your gel, did any of your experimental samples contain dyes that did not match the four reference dyes? All of the sample dyes corresponded to a reference dye, however, we found that yellow 5 was not found in any of the sample dyes.  2. Look at the structures of the dyes pictured here. Which of these dyes would migrate similarly to the dyes you examined in this lab? Why? I think blue 1, beetroot red, and carminic acid would travel at similar rates because they are similar sizes. Citrus red 2 and fast green FCF would go at similar paces to the rest of the dyes. 3. Many popular dry dog foods and dog treats have FD&C dyes among their ingredients. For example, Beneful dry food contains Yellow 5, Red 40, Yellow 6, and Blue 2, and Snausages Breakfast Bites contain Red 40 lake, Yellow 6 lake, and Yellow 5 lake. (Lake dyes are the insoluble forms of the FD&C dyes.) Why do dog food manufacturers put artificial food colors in dog food?  Dyes are

Bleaching Jeans!

In the jean lab, we set out to answer what concentration of bleach is best to fade the color out of new denim material in 10 minutes without visible damage to the fabric. Our hypothesis was if bleach breaks down pigments, then the denim will lose its color. We found that the 'best' concentration is dependent on what you're looking for and value. The 100% bleach had the most drastic results with an average of 9 in color removal. In the end, the pigment was more yellow than white. The fabric square was stiffer and the ends were frayed. (The ends were frayed because we cut it. Normally, when bleaching jeans, the hem wouldn't get frayed). This led it to have a fabric damage of 1 1/3. I would consider this one the 'best' because though the fabric turned yellow and is most likely not favorable, it took the color out of the denim. From reliable online sources, you can find data that supports our findings. This also proved our hypothesis because the bleach broke down th
