AI Thread Summary
Polysaccharide dissolution in solvents, particularly water, primarily involves the breaking of hydrogen bonds between macromolecules while maintaining the integrity of glycosidic bonds. This means that the polymeric structure remains intact, and individual monomers do not typically dissolve in the solution. Glycosidic bonds are resistant to hydrolysis under normal conditions, such as room temperature and neutral pH. The discussion specifically addresses the behavior of hemicellulose xylan when dissolved in water, confirming that it retains its polymeric form rather than breaking down into monomers.

I would like to understand more about the mechanism of polysaccharide dissolution in a solvent that which it is soluble in. Do they maintain polymeric structure (glycosidic bonds) and only lose side-chain bonding (H-bond) among each other? Or are will their glycosidic bonds be compromised resulting in individual monomers dissolving in the solution?

Or does this question even make sense? The real reason why I asked this question is that I just want to know what form the hemicellulose xylan takes when dissolved in water.

Thanks!

Usually dissolving polysacharides in water will only break hydrogen-bonding between macromolecules. The glycosidic bonds should be maintained intact. These bonds are fairly resistant to hydrolysis at room temperature and neutral pH.

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
