The α-galactosidase of fresh brewers' yeast, or a derived acetone powder, is able to polymerize d-galactose. In a typical experiment galactose was polymerized to the extent of 7.5%, some 60% appearing as 6-O-α-d-galactopyranosyl-d-galactose. Other products included the α-1 → 3-, α-1 → 4-, and α-1 → 5-galactobioses, this being the first synthesis of the last-named compound.
