De novo synthesis of short-chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys. [PDF]

open access: yesFEBS Open Bio
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

One-Bond 13C-13C Spin-Coupling Constants in Saccharides: A Comparison of Experimental and Calculated Values By Density Functional Theory Using Solid-State 13C NMR and X-Ray Crystallography [PDF]

open access: yes, 2022
Methyl aldohexopyranosides were 13C-labeled at contiguous carbons, crystallized, and studied by single-crystal X-ray crystallography and solid-state 13C nuclear magnetic resonance (NMR) spectroscopy to examine the degree to which density functional ...

Temperature Cycling Enables Efficient 13C SABRE-SHEATH Hyperpolarization and Imaging of [1-13C]Pyruvate [PDF]

open access: yes, 2021
Current metabolic imaging in humans is dominated by positron emission tomography (PET) methods. An emerging non-ionizing alternative for molecular imaging is hyperpolarized MRI. In particular, imaging of hyperpolarized 13C-pyruvate is a leading candidate

Compartmentation of glycogen metabolism revealed from 13C isotopologue distributions [PDF]

open access: yes, 2011
Background: Stable isotope tracers are used to assess metabolic flux profiles in living cells. The existing methods of measurement average out the isotopic isomer distribution in metabolites throughout the cell, whereas the knowledge of compartmental ...

13C-direct detected NMR experiments for the sequential J-based resonance assignment of RNA oligonucleotides [PDF]

open access: yes, 2010
We present here a set of 13C-direct detected NMR experiments to facilitate the resonance assignment of RNA oligonucleotides. Three experiments have been developed: (1) the (H)CC-TOCSY-experiment utilizing a virtual decoupling scheme to assign the ...
