Carob bean galactomannans

Carob bean gum, or locust bean gum, is another type of mainly neutral galactomannan, and is found in the seeds of the leguminous Ceratonia siliqua Linn. Interestingly, carob... 

Like guaran, and the endosperm polysaccharides of other legumes, locust bean (carob)gum [900040-2] is also a galactomannan. Like guaran, it has a linear backbone of (1 — 4)-linked 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 principal commercial source of galactomannans, at present, is locust bean seed. Carob trees (Ceratonia siliqua) are cultivated widely in southern Europe, on Mediterranean islands, and in northern Africa.

Galactomannans are neutral polysaccharides isolated from seeds (carob, guar, locust bean, tara, etc.). Their main chain is made of [(1 4)- 3-D-Man] (Man = mannose M units) with different degrees of substitution on 0-6 with a-D-galactop5Tanosyl units (G). Their composition (or M/G ratio) is easily determined by H NMR.
