The role of stachyose synthase in the oligosaccharide metabolism of legume seeds

Legume seeds contain two major classes of soluble α-galactosides, namely the raffinose family of oligosaccharides and galactosyl cyclitols. They are biosynthetically linked by the enzyme stachyose synthase [galactinol-raffinose galactosyltransferase], which not only forms stachyose from raffinose and galactinol, but also catalyses the galactinol-dependent synthesis of galactosyl cyclitols.

Stachyose Uses

As one non-reducing oligosaccharide, stachyose, under normal conditions, will not react with other chemical substances such as food additives and host crystal, nor affect special smells and flavour of other substances; therefore, it is a perfect functional ingredient. Human intestines can’t digest galactosidase, stachyose will not be destroyed in digestive Read more…
