Selective Enzymatic Synthesis of Glucose Fatty Acid Esters in a Choline Chloride-Glucose Reactive Deep Eutectic Solvent. [PDF]

ChemSusChem
Choline chloride–glucose reactive deep eutectic solvents direct lipase‐catalyzed acyl transfer toward glucose esters by restricting water‐ and choline‐mediated side reactions. Control of water content and solvent composition enables selective glucose monolaurate synthesis at high substrate loading, delivering a volumetric productivity of 12 g L−1 h−1 ...

The Effect of Different Matrix Bound on the Transesterification Activity of Immobilized PPD2 Lipase

, 2018
Immobilization of thermostable lipase from Geobacillus thermoleovorans PPD2 (Lip-A) were carried out on Ni-NTA agarose and carboxymethyl chitosan. Free enzyme was obtained by heterologous expression in Escherichia coli as a host cell.

Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives

European Journal of Organic Chemistry, EarlyView.
Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.

Bridging Flavour and Fragrance: A Behaviour‐Based Olfactory Pyramid for Whisky Maturation Inspired by Perfumery Principles

Flavour and Fragrance Journal, EarlyView.
This framework transposes the perfumery olfactory pyramid to whisky maturation by sequencing aromas into top, heart, and base notes according to their temporal persistence. Using Log P as a behaviour‐based classification axis and oak macromolecules as natural fixative analogues, it proposes a behaviour‐based aromatic wheel bridging flavour chemistry ...

Anti‐Inflammatory Effects of Punicic Acid and Its Molecular Mechanisms in RAW264.7 Cells and Zebrafish

Food Safety and Health, EarlyView.
Punicic acid (PA) was enriched and purified from PSO by molecular distillation with significant anti‐inflammatory activity to RAW264.7 cells, as well as to zebrafish. Anti‐inflammatory mechanism involved regulating NF‐κB and MAPK signaling pathways. ABSTRACT Punicic acid (PA) is the main fatty acid in pomegranate seeds, which shows multiple biological ...

Silicon differentially protects PSII and PSI photochemistry and preserves fatty acid metabolism in salt‐stressed Sorghum bicolor (L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Silicon (Si) has been demonstrated to be an important element to enhance crop tolerance against salinity. Nevertheless, mechanisms underlying Si's mitigation of salt stress remains insufficiently explored and understood. This study aims to provide new insights into Si's impact on salt‐stressed Sorghum bicolor (L.) supplied or not ...
