Fabrication of Polypyrrole–Polystyrene Sulfonate by Amperometric Biosensor‐Based Electropolymerization for Cholesterol Determination in Serum

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Since cholesterol triggers many diseases, many methods have been developed for its determination. In this study, an alternative system for cholesterol determination was developed by preparing amperometric biosensors. In the development of the biosensor, Pt/polypyrrole–polystyrene sulfonate film was prepared by electropolymerization of ...

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Study on the Screening of Anti‐Osteoporosis Components in Processed Epimedium‐Based on Spectrum‐Effect Analysis

Chemistry &Biodiversity, EarlyView.
ABSTRACT Epimedium (EP) is a traditional Chinese medicine that has been used to treat osteoporosis for several years, but its mechanism of action is unclear. We used ultrahigh‐performance liquid chromatography coupled with triple–quadrupole mass spectrometry (UPLC–QQQ–MS/MS) to detect the components of raw and processed EP samples.

Selective Oxidation of α,β‐Unsaturated Alcohols With Lyophilisates of Bjerkandera adusta

Chemistry &Biodiversity, EarlyView.
ABSTRACT The biocatalytic aerobic production of (E)‐2‐allylic aldehydes from their corresponding alcohols using lyophilisates of the basidiomycetous fungus Bjerkandera adusta is reported. The addition of small amounts of organic solvents to the reaction media increased the reaction and substrate conversion rates, allowing for to produce (E)‐aldehydes ...

Rational Design of Hydrophilic Deep Eutectic Solvents to Outperform Oxidoreductase Activity in Aqueous Media

ChemCatChem, EarlyView.
This study investigates the catalytic performance of alcohol dehydrogenases (ADHs) — including thermostability, specific activity, and kinetics — in mixtures of glycerol‐based deep eutectic solvents (DESs) and aqueous buffers. By elucidating enzyme—DES interactions, the work identifies the outperforming hydrophilic DESs that enhance redox biocatalysis,
