UDP-Galactose is a monosaccharide involved in nucleotide sugar metabolism. UDP-Galactose and its derivatives act as a natural agonist for Gi protein-conjugated P2Y14 receptors in the immune system (IC50=0.67 μM, hP2Y14)[1].
ChEBI: UDP-alpha-D-galactose is a UDP-D-galactose in which the anomeric centre of the galactose moiety has alpha-configuration. It has a role as a mouse metabolite. It is a conjugate acid of an UDP-alpha-D-galactose(2-).
