How does the structure of carob galactomannan differ from soya galactomannanl?

Modified on Wed, 5 May, 2021 at 3:53 PM

Carob galactomannan and Soya galactomannan both have a 1,4-beta-D-mannan backbone and galactose as alpha-1,6-linked single units.  Carob has about 23% galactose and soy has 32%.  Both are hydrolysed rapidly and to a high degree by beta-manannase. The distribution of galactosyl residues in these two galactomannans is quite different, refer to the two papers below:


McCleary, B. V. (1979). Enzymic hydrolysis, fine structure, and gelling interaction of legume seed D-galacto-D-mannans. Carbohydrate Research, 71, 205-230.
