Chemical Information
NameStachyose
DescriptionIsolated from soybean meal (Glycine max), tubers of Japanese artichoke (Stachys tubifera) and lentils Stachyose is a tetrasaccharide consisting of two D-galactose units, one D-glucose unit, and one D-fructose unit sequentially linked. Stachyose is a normal human metabolite present in human milk and is naturally found in many vegetables (e.g. green beans, soybeans and other beans) and plants. The glycosylation of serum transferrin from galactosemic patients with a deficiency of galactose-1-phosphate uridyl transferase (EC 2. 7.7 12) is abnormal but becomes normal after treatment with a galactose-free diet. Adhering to a galactose-free diet by strictly avoiding dairy products and known hidden sources of galactose does not completely normalize galactose-1-phosphate (gal-1-P) in erythrocytes from patients with galactosemia, since galactose released from stachyose may be absorbed and contribute to elevated gal-1-P values in erythrocytes of galactosemic patients. (PMID: 7671975, 9499382); Stachyose is a tetrasaccharide consisting of two ?-D-galactose units, one ?-D-glucose unit, and one ?-D-fructose unit sequentially linked as gal(?1?6)gal(?1?6)glc(?1?2?)fru. Stachyose is naturally found in numerous vegetables (e.g. green beans, soybeans and other beans) and plants.
