Novel Enzymatic Synthesis of 3-hydroxybutyric Acid Oligomerswith Inserted Lactobionic Acid Moieties

open access: green, 2011
3-Hydroxybutyric acid and lactobionic acid yielded linear and cyclic oligomers in a lipase-catalyzedcondensation polymerization reaction, performed at 80°C in bulk and organic solvent systems. Novozyme435 was the most efficient biocatalyst, and a mixture of t-butanol and dimethylsulfoxide in 80:20 (v/v) ratioprovided the highest copolymer conversions ...

Serum Metabolomic Study on the Difference between Mild and Severe Acute Pancreatitis Based on Liquid Chromatography-tandem Mass Spectrometry [PDF]

open access: yesZhongguo quanke yixue, 2023
Background Mild acute pancreatitis (MAP) has a certain probability of transforming into severe acute pancreatitis (SAP) . Once SAP occurs, it will cause greater harm to patients. It is meaningful for diagnosis and treatment of pancreatitis to explore the

Acid-tolerant poly(3-hydroxybutyrate) hydrolases from moulds [PDF]

open access: yesFEMS Microbiology Letters, 1988
We have isolated some mould strains that can grow under acid conditions with poly(3-hydroxybutyrate) (PHB) as sole carbon source, and secrete PHB hydrolases active at pH values at least down to 3. An improved assay method for such enzymes using a pH stat has been developed, and used to determine the dependence of reaction rate on enzyme and polymer ...

Identification of Morphine and Heroin-Treatment in Mice Using Metabonomics

open access: yesMetabolites, 2021
Although heroin and morphine are structural analogues and morphine is a metabolite of heroin, it is not known how the effect of each substance on metabolites in vivo differs. Heroin and morphine were administered to C57BL/6J mice in increasing doses from

The Gut Microbiota and Associated Metabolites Are Altered in Sleep Disorder of Children With Autism Spectrum Disorders

open access: yesFrontiers in Psychiatry, 2020
BackgroundAutism spectrum disorder (ASD) is a type of neurodevelopmental disease that is frequently accompanied by sleep disorder. Herein, we investigated changes in the gut microbiota and its metabolites correlated with core symptoms and sleep problems ...
