Do the elements in various sugars change/vary according to their environment? Why or why not?
Answer 1:

No; sugars are compounds - their elemental composition is the same. Glucose is C6H12O6, sucrose is C12H22O11, and ribose is C5H10... changing the number of different kinds of atoms will make it a different kind of sugar, but all sugars are composed of the same three elements. If you add a nitrogen or something to a sugar, then it's not a sugar anymore.
