Metabolite Identification
Common NameRaffinose
DescriptionRaffinose is a complex carbohydrate. It is a trisaccharide composed of galactose, fructose, and glucose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, other vegetables, and whole grains. Raffinose is hydrolyzed to D-galactose and sucrose by D-galactosidase (D-GAL). D-GAL also hydrolyzes other D-galactosides such as stachyose, verbascose, and galactinol [1-O-(D-galactosyl)-myoinositol], if present. The enzyme does not cleave linked galactose, as in lactose. Raffinose is also known as melitose and may be thought of as galactose and sucrose connected via an alpha(1->6) glycosidic linkage. Thus, raffinose can be broken down into galactose and sucrose via the enzyme alpha-galactosidase. Human intestines do not contain this enzyme (Wikipedia). Raffinose is a trisaccharide occurring in Australian manna (from Eucalyptus spp, Myrtaceae) and in cottonseed meal (PubChem).
