Starch is a natural polymer. It won't dissolve until you start breaking the bonds joining the monomer units (beta glucose, if I recall correctly).

Starch is a carbohydrate (carb).
I think it's insoluable in water because of it's complex structure. It can "absorb" water molecules, they will just stick to the starch. Due to hydrogen bonds. But I think that if you rose the temp., the bonds would break and therefore, starch would eventually become soluable.
