Not trying to nitpick....
While sucrose is technically a polysaccharide most nutritionists would probably refer to it as a disaccharide (two sugar molecules - glucose & fructose).
From what I've read (and a lot of what I post is from what I've read b/c I'm not a scientist...) fructose isn't bad as long as you don't overdo it or you're not on a keto diet. I think it's something like twice as sweet as dextrose and your liver preferentially uses it to reglycogenate itself - that's assuming that your liver is at least partially depleted. If your liver doesn't need it then chances are the fructose will get turned into fat by your liver. (High fructose corn syrup is thought to be one of the biggest contributing nutritional factors to today's high obesity & metabolic syndrome rates).
Also, for those of you into life extension stuff, fructose causes more cross-linking of your cellular proteins (it gums up the works) than glucose / dextrose.
Dexrose = pretty sweet & not too sticky in its dry form.
Malto = not really sweet & can get kind of sticky. Also more prone to clumping if you don't mix your powders before shaking. Mine seems to be kind of 'staticy' too.
Ryanmo - Fruit juice is generally high in fructose.
If I'm incorrect with any of this stuff please correct me.
Take care,
