Interactions with seed galactomannans

Some plant galactomannans are also known to interact with milk proteins,310 plant lectins,311 and protein antibodies.312 It is not yet known whether these polysaccharides can exist in the form of complexes with seed proteins. Such complex-formation often results in increased stability of proteins towards heat inactivation, proteolytic degradation, and other unfavorable conditions. 

Cassia alata seeds. Several murine antigalactan immunoglobulins have been found to precipitate with willow-bark galactan, presumably by interaction with the (1 -> 6)-linked, non-reducing, D-galactopyranosyl end-groups of the polysaccharide. The chemistry of seed galactomannans has been reviewed, with sections devoted to their occurrence and function, structural aspects, the interactions with other polysaccharides, and commercial uses. ...
