Electrochemical Behavior and Antioxidant and Prooxidant Activity of Natural Phenolics

open access: yesMolecules, 2007
We have investigated the electrochemical oxidation of a number natural phenolics (salicylic acid, m-hydroxybenzoic acid, p-hydroxybenzoic acid, protocatechuic acid, o-coumaric acid, m-coumaric acid, p-coumaric acid, caffeic acid, quercetin and rutin ...

Low-Temperature Biodegradation of Lignin-Derived Aromatic Model Monomers by the Cold-Adapted Yeast Rhodosporidiobolus colostri Isolated from Alpine Forest Soil

open access: yesMicroorganisms, 2022
The contribution of cold-adapted yeasts to the emerging field of lignin biovalorization has not yet been studied. The red-pigmented basidiomycetous yeast strain Rhodosporidiobolus colostri DBVPG 10655 was examined for its potential to degrade five ...

New insights into the properties of pubescent surfaces: peach fruit as model [PDF]

open access: yes, 2011
The surface of peach (Prunus persica ‘Calrico’) is covered by a dense indumentum, which may serve various protective purposes. With the aim of relating structure to function, the chemical composition, morphology, and hydrophobicity of the peach skin was ...

Photoinitiated Intramolecular Proton Transfer in Deprotonated para-Coumaric Acid [PDF]

open access: yesThe Journal of Physical Chemistry A, 2019
Deprotonated para-coumaric acid is commonly considered as a model for the chromophore in photoactive yellow protein, which undergoes E → Z isomerization following absorption of blue light. Here, tandem ion mobility mass spectrometry is coupled with laser excitation to study the photochemistry of deprotonated para-coumaric acid, to show that the E ...

Organic Salts of p-Coumaric Acid and Trans-Ferulic Acid with Aminopicolines [PDF]

open access: yesMolecules, 2020
p-Coumaric acid (pCA) and trans-ferulic acid (TFA) were co-crystallised with 2-amino-4-picoline (2A4MP) and 2-amino-6-picoline (2A6MP) producing organic salts of (pCA−)(2A4MP+) (1), (pCA̶ )(2A6MP+) (2) and (TFA̶ )(2A4MP+)·( 3 2 H2O) (3). For salt 3, water was included in the crystal structure fulfilling a bridging role.
