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:
