Note

Galactinol belongs to the class of organic compounds known as O-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via an O-glycosidic bond. Galactinol is an extremely weak basic (essentially neutral) compound (based on its pKa). Galactinol is an intermediate in galactose metabolism. Galactinol is the fourth-to-last step in the synthesis of D-galactose and the third-to-last step in the synthesis of D-glucose and D-fructose. Galactinol is converted from UDP-galactose via the enzyme inositol 3-alpha-galactosyltransferase (EC 2.4.1.123). It is then converted into raffinose via the enzyme raffinose synthase (EC 2.4.1.82).
