説明

1. On the course of in vivo incorporation of 14C-galactose in bull-forg's heart, uridine diphophate galactose as well as uridine diphosphate glucose were recognized to be rapidly synthesized in the livers, the amount of these sugar-nucleotides being considerably high.<BR>2. Incubation of the gastric mucosa homogenate in the presence of 14C-galactose resulted to show that the homogenate contained highly active enzyme system to synthesize uridine diphosphate galactose and uridine diphosphate glucose.<BR>3. The homogenate were confirmed also to contain a potent enzyme, α-D-galactosyl transferase which is able to transfer galactose from uridine diphosphate galactose to an endogeneous acceptor to form B blood group active substance.
