Showing papers on "Glucoside published in 1974"
TL;DR: Intracellular localization studies demonstrated that the membrane vesicles containing the UDP-glucose:sterol glucosyl transferase had a sucrose density gradient profile which was similar to that of several other enzymes thought to be involved in the synthesis of cell wall polysaccharides.
50 citations
TL;DR: The dissociation of the enzyme-Concanavalin A complex and the inhibition of its formation by α-methyl- d -glucoside suggest the glycoprotein nature of the enzymes.
40 citations
TL;DR: It has been shown that the cultured cells of Nicotiana tabacum “Bright Yellow” are capable of transforming testosterone to Δ 4 -androstene-3, 17-dione, and it has been demonstrated that [4- 14 C]testosterone is actively incorporated in these transformations.
33 citations
TL;DR: Two phospho-β-glucosidases have been purified to apparent homogeneity from extracts of Escherichia coli K12, and certain nucleotides and glycolytic intermediates inhibited one or both of the enzymes, and the kinetic behavior of the inhibition was competitive in nature for all of the compounds studied.
25 citations
TL;DR: In this paper, unmodified, cyanoethylated, and crosslinked corn starches were reacted with 2,4-dichlorophenoxyacetyl chloride in pyridine to produce the corresponding 2.4-D (((2,4dichlino- phenoxy)acetic acidlesters of high acyl content).
Abstract: Unmodified, cyanoethylated, and crosslinked corn starches were reacted with 2,4-dichlorophenoxyacetyl chloride in pyridine to produce the corresponding 2,4-D (((2,4-dichloro- phenoxy)acetic acidlesters of high acyl content. Hydrolysis studies at pH 6 and 8 at ambient temperature showed that these insoluble compositions liberated varying amounts of 2,4-D and soluble 2,4-D esters by ester link and glucoside bond cleavage, respectively, at rates that indicate their possible use as controlled-release herbicides.

TL;DR: In this article, a dihydrofuranocoumarin glucoside was isolated from Zizia aptera (Gray) Fern and its structure was shown to be 8,9-dihydro-8(S )-(1-β-D-glucosyloxy-1-methylethyl)-9(R )-hydroxy-2H-furo[2,3-h]-1-benzopyran-2-one.

TL;DR: These findings provide the final evidence for a chain-lengthening mechanism leading to homologous amino acids as proposed by Underbill and Wetter in 1966.
Abstract: A chemical synthesis of specifically 14C-labelled 2-benzylmalic acid, hitherto unknown, was developed. 4-Phenylacetoacetate obtained by condensation of phenylacetyl chloride-1-14C with ethyl acetoa...
TL;DR: In the aerial parts the uptake of radioactivity was rapid in the cycloartenol and lipidphytosterol fractions, but less so in the glucoside phytosterols, but in the roots the glucose incorporation of label was considerably more rapid than in the lipid fraction.
Abstract: d. l. [2-14C] mevalonic acid was fed to Digitalis purpurea flowering plants and the 4-4′-dimethyl and phytosterol fractions isolated at time intervals from the glucoside and lipid portions of the plant extract. The incorporation of mevalonic acid was determined in both the aerial parts and the roots over a period of 35 days. In the aerial parts the uptake of radioactivity was rapid in the cycloartenol and lipid phytosterol fractions, but less so in the glucoside phytosterols. In the roots the glucoside phytosterols incorporation of label was considerably more rapid than in the lipid fraction.
TL;DR: The structure of aloenin, a bitter glucoside from Aloe species, has been investigated and elucidated to be 6-(2′-β-D-glucopyranosyloxy-4′-hydroxy-6′-methyl)phenyl-4-methoxy-2-pyrone as mentioned in this paper.
Abstract: The structure of aloenin, a bitter glucoside from Aloe species, has been reinvestigated and elucidated to be 6-(2′-β-D-glucopyranosyloxy-4′-hydroxy-6′-methyl)phenyl-4-methoxy-2-pyrone (2) by a combination of the chemical and spectroscopic methods.
TL;DR: The kinetics of α-methyl- d -glucoside accumulation by rat kidney cortex slices under conditions of varying extracellular pH are compared with values obtained at pH 7.4, which shows a diminished initial uptake and reduced influx of the sugar which results in a decrease in the steady-state intracellular pool.
