Science Buddies: "Ask an Expert"

Hi,
I was going to test which crops is the most efficient one to get biofuels from, but I discussed it with my teacher and we thought that it would be better if we get them from wastes. So my question is does fruits' peels or seeds have glucose? I heard that used papers have glucose. Does other used materials have glucose? And is there a way to create and control heat without (I know electricity but if there are other ways)?

Hi chan111298,

You have a very interesting project idea! Let's tackle each of your questions.

Glucose is a carbohydrate (sugar molecule), and can be present in different materials.
This project describes how to measure sugar content in bananas: https://www.sciencebuddies.org/science- ... p063.shtml
This one measures glucose in fruit juices: https://www.sciencebuddies.org/science- ... p049.shtml
You could use these to design your own experiment to detect which substances contain glucose.

I'm not sure I understand your other question...

Can you rephrase that?
