It has been discovered that galactomannans interact with a number of bacterial polysaccharides.168 The most studied has been the interaction with the exo-polysaccharide from Xanthomonas campestris. Mixtures of this non-gelling polysaccharide with locust-bean gum form firm, rubbery gels at total-polysaccharide concentrations181 211 greater than 0.5%. The gels are firmest at a Xanthomonas polysaccharide locust-bean gum ratio of 1 3. 

Among the plant polysaccharides there may be mentioned the hemi-celluloses the most common of these contain 4-O-methyl-D-glucuronic acid as branch units linked to a /3-D-xylan backbone.110 The commercially important gum arabic, a soluble polysaccharide produced by Acacia trees and widely used in foods and pharmaceuticals, also contains glucuronic units.111 D-Glucuronic acid has been found in sulfated complex polysaccharides from brown algae.112... 

Many polysaccharides contain L-rhamnose as a constituent, and various methylated L-rhamnoses have therefore been isolated by the hydrolysis of methylated gums and mucilages. For example, trimethyl-L-rhamnopyranose has been isolated from methylated gum arabic86 and from the methylated polysaccharide from the somatic portion of the cells of Mycobacterium tuberculosis,26 and in both these polysaccharides L-rham-nopyranose residues evidently occupy terminal positions in the molecule. 

Carbohydrates, in the form of gums, polysaccharides, oligomers, and monomeric sugars, are readily available in large quanitities from renewable biomass resources. Each of these substances, either directly or in a chemically modified form, is a source of intermediates (derivatives) that have potential use in adhesive formulation. Carbohydrates have been utilized historically for and in adhesives and are likely to be used more and more in the future as petroleum-derived chemicals become scarce and prices increase. Appropriate research emphasis can effectively further their use as adhesive raw material.

PROP Contains 3-8% volatile oil (pinene, dipentene, etc.), 60% resins, 20% gum (polysaccharide fraction), and 6-8% bassorin (FCTXAV 16,637,78). A gum from the trees Boswellia carterii Birdw. and other Boswellia species (Fam. Burseraceae). 

Many other polysaccharides have been investigated as gums, but have not reached the status of commercial viability. Among these are polysaccharides from chia seeds [93], corn hull (corn fiber), flaxseed [93], okra [93], and tamarind seeds [93] (used in India).

Definitive proof of the location of L-rhamnopyranosyl residues in gum arabic was obtained on acetolysis of the carboxyl-reduced polysaccharide, from which degradation, 4-O-L-rhamnopyranosyl-D-glu-cose (19) and 0-L-rhamnopyranosyl-(l — 4)-0-D-glucopyranosyl-(1 — 6)-D-galactose (20) were identified as products of partial...
