Naturally p-hydroxybenzoylated lignins in palms [PDF]

open access: yes, 2015
The industrial production of palm oil concurrently generates a substantial amount of empty fruit bunch (EFB) fibers that could be used as a feedstock in a lignocellulose-based biorefinery.

Genome analysis of five recently described species of the CUG-Ser clade uncovers Candida theae as a new hybrid lineage with pathogenic potential in the Candida parapsilosis species complex [PDF]

open access: yes, 2022
Candida parapsilosis species complex comprises three important pathogenic species: Candida parapsilosis sensu stricto, Candida orthopsilosis and Candida metapsilosis. The majority of C. orthopsilosis and all C.

Photodissociation dynamics of hydroxybenzoic acids

open access: yesThe Journal of Chemical Physics, 2011
Aromatic amino acids have large UV absorption cross-sections and low fluorescence quantum yields. Ultrafast internal conversion, which transforms electronic excitation energy to vibrational energy, was assumed to account for the photostability of amino acids.

Antioxidant activity and calcium binding of isomeric hydroxybenzoates [PDF]

open access: yes, 2017
The association constant for calcium binding to hydroxybenzoates in aqueous 0.16 M NaCl at 25 °C was found electrochemically to have the value Kass = 280 mol L−1 with ΔHo = −51 kJ mol−1, ΔSo = −122 J mol−1 K−1 for the 2-isomer (salicylate), Kass = 7 mol ...

Cu‐Catalyzed Aerobic Oxidative C─C Cleavage in Lignin‐Derived Oligomers and Biological Funneling of the Monomeric Products

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Catalytic aerobic oxidation under aqueous alkaline conditions promotes C–C cleavage in pine‐ and poplar‐derived lignin oligomers, accessing high yields of aromatic monomers. The monomeric phenols obtained from this process then undergo effective biological conversion into cis,cis‐muconic acid and 2‐pyrone‐4,6‐dicarboxylic acid using engineered strains ...

Lignin biosynthesis in wheat (Triticum aestivum L.): its response to waterlogging and association with hormonal levels [PDF]

open access: yes, 2016
Phylogenetic relationships of wheat C3H and CCoAOMT genes with the homologs from other species. Phylogenetic trees of C3H (A) and CCoAOMT (B) were generated based on nucleic acid sequence similarity of wheat genes with 15 C3H and 19 CCoAOMT genes ...

Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

open access: yesThe FEBS Journal, EarlyView.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Determination of methylparaben from cosmetic products by ultra performance liquid chromatography [PDF]

open access: yes, 2009
A new method for the determination of methylparaben by ultra-performance liquid chromatography (UPLC) was developed. Methylparaben is often used as preservative, alone or in combination with other parabens, being added to cosmetic products ...

Diffusion Coefficients Of Aqueous Phenols Determined By The Taylor Dispersion Technique: Evidence For Solute Adsorption On The Walls Of Teflon Tubing [PDF]

open access: yes, 2015
The Taylor dispersion technique has been used to determine the diffusion coefficients of the m-alkoxyphenol and alkyl p-hydroxybenzoate homologous series in aqueous 5 × 10-3 mol dm-3 NaOH solutions and water-ethanol mixtures.
