Measurements of uridine diphosphate glucose and uridine diphosphate galactose — an appraisal

European Journal of Pediatrics, 1995
The recent disproof of a major deficiency of uridine diphosphate galactose in galactosemia should not lead investigators to assume either that enzymatic methods are unreliable for uridine sugar assays or that a defect in galactosylation in galactosemia has been excluded.

Studies on uridine diphosphate-galactose pyrophosphatase and uridine diphosphate-galactose: Glycoprotein galactosyltransferase activities in microsomal membranes

Archives of Biochemistry and Biophysics, 1975
Abstract Rat liver microsomes showed very active uridine diphosphate-galactose pyrophosphatase activity leading to the hydrolysis of uridine diphosphate-galactose into galactose1-phosphate and finally into galactose. The activity was observed in presence of buffers with wide ranges of pH.

Deficit of uridine diphosphate galactose in galactosaemia

Journal of Inherited Metabolic Disease, 1989
SummaryThe levels of uridine diphosphate galactose (UDPGal) and uridine diphosphate glucose (UDPGlc) have been determined in liver autopsy samples, erythrocytes and cultured skin fibroblasts from galactosaemic patients and compared to non‐galactosaemic controls.

Prenatal determination of uridine diphosphate galactose-4-epimerase activity

Prenatal Diagnosis, 1983
AbstractA prenatal diagnosis has been performed in a pregnancy at risk for uridine diphosphate galactose‐4‐epimerase deficiency, an enzyme variation causing severe symptoms in the neonatal period similar to those of classical galactosaemia. The postnatal enzyme investigation, and uneventful development of the child, indicate that the prediction of an ...

HPLC analysis of uridine diphosphate sugars: decreased concentrations of uridine diphosphate galactose in erythrocytes and cultured skin fibroblasts from classical galactosemia patients

Clinica Chimica Acta, 1995
Abstract A high performance liquid chromatography (HPLC) method has been developed for the measurement of uridine diphosphate galactose (UDPGal) and uridine diphosphate glucose (UDPGlc) in erythrocytes and cultured skin fibroblasts of normal controls and galactosemia patients.

Erythrocyte uridine diphosphate galactose-4-epimerase deficiency identified by newborn screening for galactosemia in the United States [PDF]

Screening: Journal of the International Society of Neonatal Screening, 1993
Eight infants (two whites and six blacks) with erythrocyte uridine diphosphate galactose-4-epimerase (epimerase) deficiency were identified in four newborn screening programs for galactosemia in the United States.

Uridine Diphosphate Galactose 4-Epimerase Deficiency

Archives of Pediatrics & Adolescent Medicine, 1980
In addition to the galactosemias associated with galactose-1-phosphate uridylyltransferase and galactokinase deficiency, uridine diphosphate (UDP) galactose 4-epimerase deficiency is a third disorder of galactose metabolism characterized by the inability to epimerize UDPgalactose and UDPglucose.
