Hi there, I have a quick question which I'm really stumped on.

Question

1. When combined with Lugol's solution (iodine), does glucose and sucrose contain starch?

I think glucose has starch but not sucrose. Is this right?

Answer 1

Because Glucose is the unit from which starch, cellulose and glycogen are made up, and because of its special role in biological processes, there are probably more glucose groups in Nature than any other organic group. It is extremely important in Nature as one of the main energy sources for living organisms, both in plants and animals.

Answer 2

sucrose does not

Answer 3

thanks so much for explaining!
