Like guaran, and the endosperm polysaccharides of other legumes, locust bean (carob)gum [9000-40-2] is also a galactomaiman. Like guaran, it has a linear backbone of (1 — 4)-1inked P-D-mannopyranosyl units. However, in locust bean gum, approximately one of every 3.9 P-D-mannopyranosyl units, on the average, is substituted with an a-D-galactopyranosyl unit attached at 0-6. 

The electrochemical protection of chemical plants is a question of customizing and therefore no universally applicable cost data can be established. Since chemical equipment and the materials used in its construction are proportionately more expensive and frequently other protection methods give no absolute guaran-... 

Notwithstanding the chemical differences (alcohol groups in guaran, carboxyl groups in xanthan, and partially esterified carboxyl groups in pectin) these three polysaccharides in combination with chitosan in the microspheres appear to be able to bring chitosan into solution. This is particularly interesting if one considers the solubility of these three polysaccharides in water and their important applications in the food and pharmaceutical industries.

Hydroxyalkylcellulose. Reaction of cellulose with ethylene or propylene oxides produces hydroxyethyl or hydroxypropyl derivatives. By forming the hydroxyethyl derivative about the same ratio of hydrogen bonding sites to carbon atoms is provided as in the underivatized cellulose, but the substituent groups reduce the fit between polymer chains so that the derivative can be dissolved in water to produce stable solutions. The cellulose derivative has many of the solution properties of guaran.
