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

, 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

Advanced 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 ...

Iridium‐Catalyzed Enantioselective Intramolecular Hydroarylation of Allenes: Formal Synthesis of (+)‐Rhazinilam

Angewandte Chemie, EarlyView.
A highly enantioselective iridium‐catalyzed hydroarylation of allene‐tethered pyrroles and indoles that provides access to relevant heterocyclic systems bearing vinyl‐substituted 3ry or 4ry stereocenters is reported. Its synthetic potential was exemplified with a very short, highly enantioselective formal synthesis of (+)‐Rhazinilam, whereas DFT ...

Pre-symptomatic activation of antioxidant responses and alterations in glucose and pyruvate metabolism in Niemann-Pick Type C1-deficient murine brain. [PDF]

PLoS ONE, 2013
Niemann-Pick Type C (NPC) disease is an autosomal recessive neurodegenerative disorder caused in most cases by mutations in the NPC1 gene. NPC1-deficiency is characterized by late endosomal accumulation of cholesterol, impaired cholesterol homeostasis ...

PHOSPHO1 Suppresses Ferroptosis in Retinal Pigment Epithelial Cells by Reducing the Levels of Phosphatidylethanolamine Molecular Species

Advanced Science, EarlyView.
Iron‐induced lipid peroxidation of phosphatidylethanolamine (PE) species is the key driver of ferroptosis. The authors discovered that PHOSPHO1 lowers the level of PE in retinal pigment epithelial cells thus reducing the formation of lipid peroxides. Lowering PE levels can also prevent the creation of autolysosomes, reduce the production of free iron ...

Electron bifurcation mechanism and homoacetogenesis explain products yields in mixed culture anaerobic fermentations [PDF]

, 2017
Anaerobic fermentation of organic wastes using microbial mixed cultures is a promising avenue to treat residues and obtain added-value products. However, the process has some important limitations that prevented so far any industrial application.

On/Off O2 switchable photocatalytic oxidative and proto decarboxylation of carboxylic acids.

Journal of Organic Chemistry, 2019
Photoredox catalysis in recent years has manifested a powerful branch of science in organic synthesis. Although merging photoredox and metal catalysts have been widely used, switchable heterogeneous photoredox catalysis has rarely considered.
