Cellulose is insoluble in water because of its tightly packed structure.

I think the other two are soluble, though gylcogen moreso than starch.

Generally, polysaccharides are insoluble. Think about it: they are HUGE molecules made up of glucose monomers. They're ability to form hydrogen bonds with water is low, because of their size, and so are insoluble.

They are, however, polar.

So the Intramolecular forces are GREATER, then the strength of the Hydrogen bonding?
Meaning its insoluble, due to the low formation of H Bonds?

No, not intramolecular forces... intermolecular forces between the monomers are "greater", making it insoluble.
They are soluble at certain conditions (under very high pressure and temperature), but GENERALLY are insoluble.

Ahhhhhh!
Yep, Inter = between.
Yeah, thanks I get that clear

Ah, I was thinking that they would be hydrolised and thus split into smaller molecules(maltose), making it soluble. But I suppose this is not glycogen or starch anymore...

Yep, I agree that they are not soluble.

The way I think of it is that you have a certain amount of O-H bonds in a monosaccahride.
Each time you bond you lose 2.

Eventually all those other little O-H will be insiginificant.

[m@tty]

No, these polymers are still very polar.

[Martoman]

Proportionally increasing sure, it will be pretty big though so the forces would be like nah im not splitting

As wiki says "They may be amorphous or even insoluble in water."
Theyre just so dense when they're bigger, like long-chain alkanols.
