Raffinose is a complex carbohydrate, 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 hydrolysed to D-galactose and sucrose by D-galactosidase (D-GAL) (1). D-GAL also hydrolyses 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. -- Wikipedia; Raffinose 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 can be hydrolyzed to D-galactose and sucrose by the enzyme ?-galactosidase (?-GAL), an enzyme not found in the human digestive tract. ?-GAL also hydrolyzes other ?-galactosides such as stachyose, verbascose, and galactinol, 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 + sucrose connected via an alpha(1-6) glycosidic linkage and so raffinose can be broken apart into galactose and sucrose via the enzyme alpha-galactosidase. Human intestines do not contain this enzyme. -- Wikipedia; Trisaccharide; A trisaccharide occurring in Australian manna (from Eucalyptus spp, Myrtaceae) and in cottonseed meal. -- Pubchem.
