Can you identify these substances?

Question

I'm writing a lab report for a lab excersize testing for the presence of macromolecules... I'm trying to figure out what these substances could possibly be - you don't need to be sure, and I would be more than happy if you gave more than one possible answer for each substance. Just looking for ideas as it is 2 am and I am coming up blank.

Substance 1:
Tested positive for the presence of; Protein, Starch, and Sugar.
Tested negative for the presence of; Lipid.

Substance 2:
Tested positive for the presence of; Sugar.
Tested negative for the presence of; Protein, Starch, and Lipid.

Thanks for any help you can provide!

I should have said this right away, but substance 1 is a clear slightly viscous liquid and substance 2 is a transparent yellow non-viscous liquid.

Answer 1

I'm winging it here, could be anything. But I say 1 is an apple and 2 is a can of coke.

Answer 2

Substance 1: - Raw Cocaine
Substance 2: - Pig's Blood
