Hello everyone and today we'll be discussing cellulosis solubility in water or more accurately celluloses insolubility in water.
00:09
So as you can see, cellulose is composed of glucose molecules, or yes, glucose molecules that are all lined up, which would be glucose monomers to create a cellulose polymer.
00:23
So these are all glucose and they are attached to one another.
00:27
But the thing that makes, you may be asking, why is cellulose insoluble if it's polar? because its side chains are polar, so therefore cellulose is polar.
00:40
Well, the thing is, is that despite being polar, despite being polar, cellulose in cellulose monomers are connected, glucose monomers are connected via interchain hydrogen bonding.
00:59
Which, as you can see right here, these are interchained hydrogen bonding, which it creates a rather rigid structure.
01:08
So rigid structure, rigid structure of layered sheets of cellulose...
