UDP-Galactose
Based on 5 publication(s) in Google Scholar
UDP-Galactose is a monosaccharide and a key glycosyl donor molecule in cells that participates in nucleotide sugar metabolism. UDP-Galactose is the natural agonist of the P2Y14 receptor coupled to Gi proteins in the immune system (IC50 = 0.67 μM, hP2Y14). UDP-Galactose can be used to study cell signal transduction and substance metabolism.
