Epoxy vitrimers with a covalently bonded tertiary amine as catalyst of the transesterification reaction

European Polymer Journal, 2019
Tertiary amines are one of the typical catalysts used to accelerate transesterification reactions in epoxy vitrimers. Instead of adding a tertiary amine (e.g. tributylamine, TBA) to the initial formulation, secondary (e.g.

Biosynthesis of Sciadonic Acid Derived from Gymnosperms with Anti‐Colitis Activity

Advanced Science, EarlyView.
This study establishes an efficient Yarrowia lipolytica platform for unusual sciadonic acid (SCA) production and assess the anti‐colitis efficacy in mice of SCA, supporting its potential as a novel therapeutic lipid. ABSTRACT Sciadonic acid (SCA), Δ5‐unsaturated fatty acid with anti‐inflammatory and lipid‐regulatory properties, is predominantly derived
