|Guar Gum is a natural
high molecular weight hydrocolloidal polysaccharide
composition and mannan units combined through glycosidic
linkages, which may be described as galactomannan.
RAMCOL has excellent
cold & hot water solubility. Guars viscosity
is a function time, and concentration.
Chemical structure of RAMCOL:
As per Iupac System of nomenclature, RAMCOL
is a galactomannan polysaccharide.
The molecular structure reveals that RAMCOL
is a straight chain galactomannan with galactose
on every other mannose unit. Beta 1Ý4 Glycosidic
linkages couple the mannose units and the galactose
side chains are linked through alpha 1Ý6.
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 RAMCOL 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
