The joy of yeast :P

I'm doing my biology coursework on the effects of different sugars on the respiration of yeast.
The sugars are:
Glucose, Galactose and fructose (monosaccharides)
Sucrose, Maltose and Lactose (disaccharides)

I have no idea how to work out which order they will react in (or why).
I know that the monosaccharides will react most quickly - glucose will be fastest.
But apart from that, i'm not really sure which order the other 5 sugars will go in!
Im sure that the structure has something to do with it....

Any help would be greatly appreciated, even just a link to somewhere that 'knows'

Try samples of yeast in each sugar. The one where the yeast give the most respiratory product (CO2 or whatever you're measuring) the quickest is the sugar that reacts the quickest methinks.

Also this, :yep:!

(but in fairness, i think OP said they dont know how to go about it)
Its background knowledge that I need for the prediction. It has to be completed before the experiment itself!
Believe me, I would do it that way! its just that I need to know the scientific reasoning behind it.
