I believe the answer is:

fructose

I'm a little stuck... Click here to teach me more about this clue!

'sugar' is the definition.
(fructose is a kind of sugar)

I don't understand the remainder of the clue.

(Other definitions for fructose that I've seen before include "Sweetener" , "It's sweet" , "Kind of sugar" , "A simple sugar, in honey for instance" , "Fruit-sugar" .)
