In enzymology an inositol 3-alpha-galactosyltransferase (EC 2.4.1.123) is an enzyme that catalyzes the chemical reactionUDP-galactose + myo-inositol UDP + O-alpha-D-galactosyl-(1->3)-1D-myo-inositolThus the two substrates of this enzyme are UDP-galactose and myo-inositol whereas its two products are UDP and [[O-alpha-D-galactosyl-(1->3)-1D-myo-inositol]].This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
