Effects of formulation and baking process on acrylamide formation in Kolompeh, a traditional cookie in Iran [PDF]

open access: yes, 2019
Thermal treatments and recipes are two critical aspects for the formation of acrylamide at ordinary household cooking conditions and industrial level. Kolompeh is a traditional Iranian cookie, and the aim of this study was to monitor acrylamide formation

Coupling of the Decarboxylation of 2-Cyano-2-phenylpropanoic Acid to Large-Amplitude Motions: A Convenient Fuel for an Acid-Base-Operated Molecular Switch.

open access: yesAngewandte Chemie, 2016
The decarboxylation of 2-cyano-2-phenylpropanoic acid is fast and quantitative when carried out in the presence of 1 molar equivalent of a [2]catenane composed of two identical macrocycles incorporating a 1,10-phenanthroline unit in their backbone.

Acod1 Promotes PAD4 Ubiquitination via UBR5 Alkylation to Modulate NETosis and Exert Protective Effects in Sepsis

open access: yesAdvanced Science, EarlyView.
In this study, Acod1 knockout in CLP mice significantly increases peripheral blood NET levels, exacerbating inflammation, organ damage, and reducing survival. Further research shows that UBR5 interacts with PAD4, a key NET formation protein. Acod1/itaconate (ITA) enhances the enzymatic activity of UBR5 by alkylating the Cys2768 site, promoting the K48 ...

Saccharomyces cerevisiae in the production of fermented beverages [PDF]

open access: yes, 2016
Alcoholic beverages are produced following the fermentation of sugars by yeasts, mainly (but not exclusively) strains of the species, Saccharomyces cerevisiae.

Genomic and Cis‐Regulatory Basis of a Plastic C3‐C4 Photosynthesis in Eleocharis Baldwinii

open access: yesAdvanced Science, EarlyView.
The sedge Eleocharis baldwinii remarkably switches between C3‐like and C4‐like photosynthesis in response to environmental conditions. Combining gap‐free genome assembly with single‐cell multi‐omics, this study uncovers how subgenome dominance and cell‐specific cis‐regulation enable C4 photosynthesis.

The Natural Redox Cofactor Pyrroloquinoline Quinone (PQQ) Enables Photocatalytic Radical Cyclizations

open access: yesAngewandte Chemie, EarlyView.
Natural alcohol and sugar dehydrogenases that utilize the redox cofactor pyrroloquinoline quinone (PQQ) can be repurposed for enantioselective photoredox catalysis. Upon blue‐light irradiation, redox‐neutral radical cyclizations are catalyzed. This work adds a new class of enzymes to the toolbox of photobiocatalysis.

Switchable selectivity in Pd-catalyzed [3 + 2] annulations of γ-oxy-2-cycloalkenones with 3-oxoglutarates: C–C/C–C vs C–C/O–C bond formation

open access: yesBeilstein Journal of Organic Chemistry, 2019
Two complementary [3 + 2] annulation protocols between 3-oxoglutarates and cyclic γ-oxy-2-cycloalkenones, simply differing on the reaction temperature, are disclosed.

2-pentanone production from hexanoic acid by Penicillium roqueforti from blue cheese:is this the pathway used in humans? [PDF]

open access: yes, 2014
Production of 2-pentanone, a methylketone, is increased in fasting ketotic humans. Its origin is unknown. We hypothesised that it is formed via β-oxidation of hexanoic acid by the peroxisomal pathway proposed for methylketone-producing fungi and yeasts ...

Cascade Promotion of Gas Separation Performances in CMS Membranes: MOFs With Functional Groups and Loaded Noble Metals

open access: yesAdvanced Science, EarlyView.
Novel mixed‐matrix carbon molecular sieve (MMCMS) membranes are fabricated via employing palladium‐doped carboxyl‐functionalized UiO‐66 (Pd/UiO66‐COOH)/polyimide MMM as precursor. The synergistic effect of decarboxylation‐induced thermally cross‐linking and catalytic graphitization of Pd promoted the formation of more ordered Langmuir domains, thereby ...

Selective Chemo‐Divergent Hydrogenation of Ethylene Carbonate Enabled by Multi‐Functional Poly(Ionic Liquids)‐Stabilized Ru Nanoparticles

open access: yesAngewandte Chemie, EarlyView.
A highly efficient and selective chemo‐divergent hydrogenation of cyclic carbonates is promoted by in situ generated poly(ionic liquid)‐stabilized ruthenium nanoparticles (Ru@PIL) catalysts. Under solvent‐free conditions, ethylene carbonate is transformed into either ethylene glycol and CH4 or EtOH and CO2, following a “direct hydrogenation” or a ...
