What color does Sudan III solution turn in the presence of a lipid?
range from yellow to red
blue/black
purplish/violet
red globules
Helena and Carrie were having a healthy debate about whether nuts contain lipids. Carrie said if you tested with Sudan III you could PROVE they contained lipids, Helena said you should test with iodine. Who is correct?
Carrie: Sudan III would turn red if lipids were present
Carrie: Sudan III would turn blue/black if lipids were present
Helena: iodine would turn blue/black if lipids were present
Helena: iodine would turn red if lipids were present
We need lipids to
build cell walls
build cell membranes
make the nucleus
make the cytoplasm
A test for lipids is using Sudan III solution. What does a positive result look like?
Turns Purple
A red layer forms on top
A green layer forms on top
It turns black
