carbohydrates that have a
chemical structure that
includes a five-membered ring
system consisting of four

formation due to
attack on the
aldehyde by the C4'
hydroxyl group to
produce a
furanose form or by the C5'
hydroxyl group to

pyranose form. In each case...
-
bridge between two
carbon atoms.
Rings with five and six
atoms are
called furanose and
pyranose forms, respectively, and
exist in
equilibrium with the straight-chain...

These forms are
