Common Name{[3,4-dihydroxy-5-(4-hydroxy-2-oxopyrimidin-1-yl)oxolan-2-yl]methoxy(hydroxy)phosphoryl}oxy([3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy)phosphinic acid
DescriptionUridine diphosphategalactose belongs to the class of organic compounds known as pyrimidine nucleotide sugars. These are pyrimidine nucleotides bound to a saccharide derivative through the terminal phosphate group. Uridine diphosphategalactose is an extremely weak basic (essentially neutral) compound (based on its pKa). This may reflect an inability of red cell UDPgal-4'-epimerase to maintain a normal ratio and consequently higher levels of UDPgal. Within humans, uridine diphosphategalactose participates in a number of enzymatic reactions. In particular, uridine diphosphategalactose and glucose 1-phosphate can be converted into uridine diphosphate glucose and galactose 1-phosphate; which is mediated by the enzyme galactose-1-phosphate uridylyltransferase. In addition, D-glucose and uridine diphosphategalactose can be converted into uridine 5'-diphosphate and α-lactose through the action of the enzyme lactose synthase. In humans, uridine diphosphategalactose is involved in the metabolic disorder called the congenital disorder of glycosylation cdg-iid pathway. Defective galactosylation of complex glycoconjugates exists in tissues from galactosemic patients. Uridine diphosphategalactose (UDPgal) is a nucleoside diphosphate sugar which can be epimerized into UDPglucose for entry into the mainstream of carbohydrate metabolism. Therefore, defective galactosylation observed in galactosemic fibroblasts must result from a defect in the transfer of galactose from UDPgal to these moieties. There is a tendency for galactosemic red cell UDPgal to be in the low normal range with a high uridine diphosphate glucose to UDP-gal ratio. UDPgal is a pivotal compound in the metabolism of galactose. In the more complex white blood cells and cultured fibroblasts, the UDPgal content and the uridine diphosphate glucose to UDPgal ratio of galactosemics are normal. {[3,4-dihydroxy-5-(4-hydroxy-2-oxopyrimidin-1-yl)oxolan-2-yl]methoxy(hydroxy)phosphoryl}oxy([3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy)phosphinic acid is found in Arabidopsis thaliana, Glycine max, Helianthus tuberosus and Streptomyces hygroscopicus. UDPgal is the necessary galactosyl donor of galactose in the metabolism to incorporate it into complex oligosaccharides, glycoproteins and glycolipids (galactosides).
