Description and Uses

D-(+)-Raffinose is a trisaccharide composed of galactose, glucose, and fructose that occurs naturally in a variety of vegetables and grains. It is hydrolyzed to galactose and sucrose by α-galactosidase.

D-(+)-Raffinose is a trisaccharide built from 1 mol each of D-galactose, D-glucose, and D-fructose which are obtained from it by acid hydrolysis. Invertase splits it into melibiose and saccharose. D-(+)-Raffinose occurs in Australian manna; in cottonseed meal.
