The Raffinose Family of Oligosaccharides
1954Publisher Summary This chapter discusses raffinose and those saccharides which are related to raffinose by virtue of having one or more α-D-galactopyranosyl groups in their structures. These D-galactosyl groups are found in nature joined to sugars, such as D-glucose, to sucrose, to certain polysaccharides, and to a few non-sugars, such as glycerol ...

Glucosylation of raffinose via alternansucrase acceptor reactions
Carbohydrate Research, 2009The glucansucrase known as alternansucrase [EC 2.4.1.140] can transfer glucosyl units from sucrose to raffinose to give good yields of oligosaccharides, which may serve as prebiotics. The main products were the tetrasaccharides alpha-d-Glcp-(1-->3)-alpha-d-Galp-(1-->6)-alpha-d-Glcp-(12)-beta-d-Fruf and alpha-d-Glcp-(1-->4)-alpha-d-Galp-(1-->6)-alpha-d ...

Raffinose [orO-α-D-galactopyranosyl-(1→6)-α-D-glucopyranosyl-(1→2)-β-D-fructofuranoside] pentahydrate, C18H32O16·5H2O, (I), and three lower hydrates, namely the 4.433-, (II), 4.289-, (III), and 4.127-hydrated, (IV), forms, obtained in the course of the dehydration of (I), have been studied.

[Raffinose metabolism in Gluconobacter oxydans].
Mikrobiologiia, 1976Metabolism of raffinose has been examined in experiments with the growing culture and washed cells of Gluconobacter oxydans L-1. Degradtion of the trisaccharide was found to be catalyzed by levansucrase, levan being synthesized, and melibiose and small quantitites of fructose being liberated in the reaction.

RAFFINOSE METABOLISM IN GERMINATING BARLEY
New Phytologist, 1957The trisaccharide raffinose is widely distributed throughout the Spermaphyta (French, 1954), not infrequently accounting for a substantial proportion of the free sugars of seeds, rhizomes or roots. Structurally, raffinose may be represented as a-D-galactopyranose (I -6) a-D-glucopyranose (I--2) ,-D-fructofuranose; oligosaccharides related to raffinose ...
