[Uridine diphosphate sugar in meningiomas of the brain].
Zhurnal voprosy neirokhirurgii imeni N. N. Burdenko, 1997The content of uridine-diphosphate (UDP)-saccharides, such as UDP-glucose (UDPG) and UDP-N-acetylglucosamine (UDPAG) was examined in the meningiomas obtained at surgery. Typical, atypical, and anaplastic meningiomas were used. Biochemical data were compared with histological findings. The total level of UDP-saccharides (UDPG + UDPAG) in the meningiomas

The biosynthesis of uridine diphosphate glucose and sucrose in sugar beet leaf
Archives of Biochemistry and Biophysics, 1956Abstract 1. 1. The mechanisms for biosynthesis of UDPG and sucrose in sugarbeet leaf and leaf homogenate have been investigated by providing radioactive G-1-P with various cofactors and identifying the radioactive products after short time intervals.

Characterization of uridine diphosphate-sugar pyrophosphorylase from Populus deltoids
Journal of the Korean Society for Applied Biological Chemistry, 2013Nucleotide sugars serve as sugar donors for the biosynthesis of various cell components including cell wall, glycoproteins, and small molecules. Among them, uridine diphosphate (UDP)-glucose is one of main nucleotide sugars that serve as a substrate for the synthesis of other UDP-sugars.

Abstract 1. 1. Ethionine administration to female rats in a dose of 100mg/100g body wt provokes a rise in liver UTP, UDP and UMP quantity at the 4th and 8th hr after treatment. 2. 2. A small decrease in UDP-glucose concentration and no change or an elevation in UDP- N -acetylglucosamine quantity was established at the 4th and 8th hr time ...

Uridine diphosphate-sugar metabolism by sycamore (Acer pseudoplatanus) cambial tissue
Planta, 1972Extracts of sycamore cambial tissue convert UDP-glucose into UDP-glucuronic acid, and the latter into UDP-xylose and UDP-rhamnose. None of the corresponding galactose series of monosaccharides was formed indicating the absence of epimerases, postulated as an important feature of differentiation.

The nucleotide-sugars are metabolites of primary importance in the biosynthesis of polysaccharides and glycoconjugates since they serve as sugar donors in the reactions of glycosyltransferases, enzymes that displays a high specificity for both donors and acceptors.

N-Glucosidation is known as a major metabolic reaction for barbiturates in humans. However, the enzyme(s) involved in this N-glucosidation has not been clarified yet. Thus, to clarify the enzyme(s) involved in the N-glucosidation in human liver microsomes, we investigated the N-glucosyltransferase activity in recombinant UDP-glucuronosyltransferases ...

Abstract 1. 1. [ 14 C]orotate incorporation into UDP-sugars was used for in-vivo studies of their synthesis. An equation which takes into account the relative molar specific activity (that of UMP = 100) and concentration of the compound newly formed was proposed to calculate the rate of UDP-sugar formation. 2. 2.
