Subject: Re: pinhole Sugars

I've been thinking about this question a lot. My initial reaction was
because of the high number of -OH bonds that can form hydrogen bonds,
and so the molecules can both attract one another & also attract
other surfaces. This is confirmed by the somewhat dubious site
http://www.madsci.org/posts/archives/oct98/909516337.Ch.r.html
But I remember Paul writing in a pinhole post a while ago that
sucrose actually showed London dispersion intermolecular forces and
not hydrogen bonds.
