raffinose

[raffinose (Science: biochemistry plant biology) a nonreducing trisaccharide found in sugar beet and many seeds, consisting of the disaccharide sucrose bearing a D galactosyl residue linked _(1-6) to its glucose group.

[1. A dextrorotatory trisaccharide, occurring in cotton seed and in the molasses of beet root, composed of d-galactose, d-glucose, and d-fructose and formed by transfer of d-galactose from UDP-d-galactose to sucrose; many seeds are rich in raffinose.
