As per IUPAC SYSTEM
of nomenclature,
AGCOL is a
galactomannan
polysaccharide.
The molecular
structure reveals
that AGCOL is a
straight chain
galactomannam with
galactose on every
other mannose unit.
Beta 1-4 Glycosidic
linkages couple the
mannose units and
the galactose side
chains are linked
through alpha 1-6.
The mannose to
galactose ratio has
been estimated at
1.8: 1 to 2 :1. The
molecular weight of
Guar has been
reported as 1-2 x
106. Further studies
indicate that AGCOL
is a rigid rod like
polymer because of
the beta linkage
between the monomer
units. The Guar
hydroxyls are in the
CIS positions. The
CIS position is
important since
adjacent hydroxyl
groups reinforce
each other in
hydrogen bonding
reactions.
AGCOL has excellent
cold water
solubility because
of the high
galactose: mannose
ratio. The special
properties of AGCOL
make it most
suitable for various
industrial
applications. |
