Pan‐Frying Conditions Affect the Tocopherol Intake From Edible Oils: Results From Temperature Measurements and the Standardized Heating of an Edible Oil

Journal of the American Oil Chemists' Society, EarlyView.
High temperatures in a short time on electric stoves in private homes. Fast loss of tocochromanols using standardized conditions and a miniature heating apparatus. ABSTRACT Tocochromanols (vitamin E compounds) are essential ingredients in human nutrition. Their consumption via edible oils is considered the main source of dietary intake.

Annatto‐Derived Carotenoids (Bixin and Norbixin) As Biodiesel Antioxidants: Characterization and Effects on Oxidative Stability (Rancimat and PetroOXY)

Journal of the American Oil Chemists' Society, EarlyView.
Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway

Chemistry – A European Journal, EarlyView.
Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly
