Method for preparing an at least partially acetal-protected sugar

Jeremy Luterbacher, Songlan Sun, Lorenz Perry Manker, Anastasiia Komarova

The present invention relates to a method for preparing an at least partially acetal-protected sugar involving the step of reacting a sugar or a sugar derivative selected from the group consisting of an aldopentose, an aldohexose, an aldopentoside and an a ...

Probing renal pH using hyperpolarized [1-13C]alaninamide

Rolf Gruetter, Arnaud Comment, Hikari Ananda Infinity Yoshihara, Alice Radaelli

Hyperpolarized molecular probes can be effectively used as pH markers. To date, the only two probes reported in vivo as extracellular pH sensors are 13C-bicarbonate, and [1,5-13C2]zymonic acid. Alaninamide is a derivative of alanine which is found to be se ...

Monitoring Membrane Lipidome Turnover by Metabolic N-15 Labeling and Shotgun Ultra-High-Resolution Orbitrap Fourier Transform Mass Spectrometry

Yury Tsybin, Konstantin Nagornov, Kristina Srzentic

Lipidomes undergo permanent extensive remodeling, but how the turnover rate differs between lipid classes and molecular species is poorly understood. We employed metabolic N-15 labeling and shotgun ultra-high-resolution mass spectrometry (sUHR) to quantify ...

Exploring biochemical pathways for mono-ethylene glycol (MEG) synthesis from synthesis gas

Vassily Hatzimanikatis, Meriç Ataman, Noushin Hadadi

Mono-ethylene glycol (MEG) is an important petrochemical with widespread use in numerous consumer products. The current industrial MEG-production process relies on non-renewable fossil fuel-based feedstocks, such as petroleum, natural gas, and naphtha; hen ...

Technical note: Relating functional group measurements to carbon types for improved model-measurement comparisons of organic aerosol composition

Satoshi Takahama, Giulia Ruggeri

Functional group (FG) analysis provides a means by which functionalization in organic aerosol can be attributed to the abundances of its underlying molecular structures. However, performing this attribution requires additional, unobserved details about the ...

Feeding behaviour of a benthic species (Ammonia tepida) under oxic and anoxic conditions: TEM-NanoSIMS correlation

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

More and more marine areas are subjected to depleted-O2 concentration, mainly due to eutrophication induced by human activities. These phenomena affect benthic ecosystems, in particular continental shelves and coastal areas where the renewal of the bottom ...

Reconstructing climate change and ombrotrophic bog development during the last 4000 years in northern Poland using biotic proxies, stable isotopes and trait-based approach

Vincent Eric Jules Jassey, Mariusz Lamentowicz

In this study, we present a record spanning the last 4000 years from a Baltic bog (Kusowskie Bagno) in northern Poland. Using numerous biotic and abiotic proxies, such as testate amoebae (depth to water table reconstructions), stable carbon isotopes (C-13) ...

Hyperpolarization of Deuterated Metabolites via Remote Cross-Polarization and Dissolution Dynamic Nuclear Polarization

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud

In deuterated molecules such as [1-C-13]pyruvate-d(3), the nuclear spin polarization of C-13 nuclei can be enhanced by combining Hartmann-Hahn cross-polarization (CP) at low temperatures (1.2 K) with dissolution dynamic nuclear polarization (D-DNP). The po ...

New tool for studying the biosynthetic role of glucose in brain at the nanometer scale

Anders Meibom, Graham Knott, Stéphane Laurent Escrig, Arnaud Comment, Yuhei Takado, Mojgan Masoodi

Background: The brain consumes a considerable amount of glucose relative to its size. Brain glucose is a source of energy, mainly via oxidative phosphorylation, as well as a source of building blocks for synthesising macromolecules. Little is known about t ...
