Metabolite Identification
Common NameGalactinol
DescriptionGalactinol is an intermediate in galactose metabolism. Galactinol is the. 4th to last step in the synthesis of D-Galactose and the 3rd 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 to raffinose via the enzyme raffinose synthase (EC 2.4.1.82).
