ScienceRobParticipantThe question on my study guide for my 200 level class says: What will HCL do to a monomer of glucose in a disaccaride?
My personal understanding (my labs and books don’t say it outright) is that adding Hydrochloric Acid to a polysaccaride will create a hydrolysis reaction separating the polymers into monosaccarides. Is this correct?

basically, esters are sensitive to acids

I appreciate the reply but this doesn’t really tell me if my reasoning is correct. Its interesting to know that esters are sensitive to acids (I had to wikipedia Ester to fully understand what you meant) but that doesn’t tell me if I am correct in my assumption or not. I appreciate any reply.

you are correct
polysaccharides form monosaccharides (mostly) and a little of disaacharides. depending on other conditions like temperature
higher the temperature more is the monomer formed - February 7, 2010 at 3:30 am #97337jwalinParticipant
and another thing it’s HCl and not HCL

chemistry is right there

i recall my teacher at one point of time had mentioned that at low temperatures and at low concentrations of HCl also dives dissacharides from poly saccharides.

yes, that is true, but you said, that polysaccharides are composed from mono- and sometimes from disaccharides, so I ask how that?

…lol

did i say that
quote jwalin:polysaccharides form monosaccharides (mostly) and a little of disaacharides. depending on other conditions like temperature
higher the temperature more is the monomer formedi talked about that polysaccharides 💡 form ❗
and not
polysacharidfes are formed from

I see now 🙂
anyway, the question was originally about disaccharide, so even the conclusion about polysaccharides was unneeded 🙂
- February 8, 2010 at 9:48 am #97397jwalinParticipant
as i now rereadthe question i see it was not needed
the answer is monosaccharidesbut as i had been specific i hope atleast the questioner wouldn’t have any doubts with my statement and if he or she had then they are cleared by now

I understand your response and other responses in this thread. I appreciate the assistance.
