Electrochemical generation of 2,3-oxazolidinone glycosyl triflates as an intermediate for stereoselective glycosylation

Beilstein Journal of Organic Chemistry, 2012
Glycosyl triflates with a 2,3-oxazolidinone protecting group were generated from thioglycosides by low-temperature electrochemical oxidation. The glycosyl triflates reacted with alcohols to give the corresponding glycosides β-selectively at low ...

Microbial lipid and amino sugar responses to long-term simulated global environmental changes in a California annual grassland

Frontiers in Microbiology, 2015
Global environmental change is predicted to have major consequences for carbon cycling and the functioning of soil ecosystems. However, we have limited knowledge about its impacts on the microorganisms, which act as a “valve” between carbon sequestered ...

Thinning Intensity Enhances Soil Multifunctionality and Microbial Residue Contributions to Organic Carbon Sequestration in Chinese Fir Plantations

Plants
Soil multifunctionality is essential for the enhancement of soil carbon sequestration, but disturbances such as thinning practices can influence soil microbial activity and carbon cycling.

Crystal Structure of Methyl 4-Acetamido-4-cyano-4,6-dideoxy-2,3-O-isopropylidene-ß-D-allopyranoside

Molecules, 2000
The detailed structure of methyl 4-acetamido-4-cyano-4,6-dideoxy-2,3-Oisopropylidene-ß-D-allopyranoside was established by X-ray analysis confirming allo configuration at C-4 and suggesting a 4C1 conformation of the pyranose ring.

The Influence of Traditional and Immobilized Yeast on the Amino-Acid Content of Sparkling Wine

Fermentation, 2022
This article focuses on the effect of yeast strains, vintage, and must sugar content on the amino-acid content of sparkling wines produced by the traditional method. In the experiment, the amino-acid concentrations before and after secondary fermentation,

Ad libitum consumption of protein- or peptide-sucrose solutions stimulates egg formation by prolonging the vitellogenic phase of oogenesis in anautogenous mosquitoes

Parasites & Vectors, 2022
Background Anautogenous mosquitoes commonly consume nectars and other solutions containing sugar but are thought to only produce eggs in discrete gonadotrophic cycles after blood-feeding on a vertebrate host.

Poly(butylene adipate-co-terephthalate) biodegradable microplastics accelerated the decomposition of amino sugar in soil

Cambridge Prisms: Plastics
Biodegradable microplastics (BMPs) are reported to have a priming effect on soil organic matter (SOM) decomposition. However, their impact on the turnover of specific SOM components, especially nitrogen (N)-containing ones, remains unclear.

Comparative GC–MS based nutrients profiling of less explored legume seeds of Melilotus, Medicago, Trifolium, and Ononis analysed using chemometric tools

Scientific Reports, 2023
Exploring novel sources of plant protein for nutrition of both humans and animals is motivated mainly by its growing demand worldwide, besides identifying healthy alternatives for animal protein. The present study evaluates metabolome diversity within 15

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
