it is amphipathic, contains both hydrophilic and hydrophobic parts

3

calculating percent yolk and whites

finding mass of yolk and whites requires subtracting from the beaker + thing - beaker
finding total is adding up yolk 1 and 2, and white 1 and 2

percentage is total yolk/white mass/ egg mass x 100%

4

adding acetic anhydride and sufuric acid is a test for

cholesterol (turns blue)

5

adding copper sulphate and sodium hydroxide is a test for what

protein, turns purple

6

adding iodine is a test for

triglygerices (turns dark blue)

7

which has the most amount of protein

the egg white since it has the darkest purple colour with the cup-or sulphate and sodium hydroxide

8

most unsaturated triglycerides and polar lipids

egg yolk solid most brown with iodine

The order of most brown was 3 (yolk solid) then 1 (yolk liquid) then 2 (white liquid) then 4 (white solid)

9

most cholesterol

egg yolk, it was the darkest blue

10

egg is mostly

white
