Behaviour of glucose in solution
« on: September 29, 2005, 06:03:11 AM »
Does anybody know how glucose behaves in solution when in a glass vessel? I have been told that it can 'stick' to the glass surface, but can't find any information to suggest this or to explain this.

I appreciate any thoughts you might have.

Thanks,

Sam

it's possible since glass has a positive charge and thus polar OH-groups of glucose can bind to those positive charges.

--> for example: when breeding cell cultures a glass breeding bottle is used because cells have a negative charge and glass has a positive charge.

I don't get it. Do you mean that when I am reaching for my glass there is short circuit every time?  ;)
