Competing Pathways in Heme Catalyzed Oxidations With Porphyrin‐Centered Reactivity

open access: yesChemistryEurope, Volume 4, Issue 8, August 2026.
Heme‐catalyzed oxidations proceeding through porphyrin‐centered reactivity are quite rare. In attempts to optimize the catalytic umpolung of chloride proceeding via an isoporphyrin, we found a competing pathway. The iron(III) π‐dication readily performs alternative reactivity, leading to a bifurcation in reaction mechanisms at this point.

Visible‐Light‐Gated Rh‐Catalyzed Intermolecular [2 + 2 + 2] Cycloaddition of Alkynes Enabled by Coordination‐State Control

open access: yesChemistryEurope, Volume 4, Issue 8, August 2026.
Visible‐light‐gated Rh catalysis enables intermolecular [2 + 2 + 2] cycloaddition of alkynes via coordination‐state control. Blue‐light irradiation promotes ligand dissociation to generate coordinatively unsaturated Rh species that enable multialkyne coordination and cyclotrimerization.

Seaweed‐Derived Proteolytic Extracts as Natural Interfacial Stabilizers for Oxidatively Sensitive DHA‐Rich Oil‐in‐Water Emulsions

open access: yesEuropean Journal of Lipid Science and Technology, Volume 128, Issue 8, August 2026.
Red seaweed extracts have potential to protect DHA‐rich emulsions against oxidation while maintaining their physical stability. Their combined antioxidant and interfacial properties make them promising clean‐label ingredients for omega‐3‐enriched foods.

Effects of Exogenous Monosodium Glutamate on GABA Accumulation and Volatile/Nonvolatile Metabolites in Black Highland Barley

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Overview of MSG‐assisted GABA enrichment and associated changes in amino acid, fatty acid, and volatile metabolite profiles in germinated black highland barley. ABSTRACT γ‐Aminobutyric acid (GABA) is a functional amino acid with multiple health benefits; however, the mechanism of its enrichment in black highland barley, particularly through precursor ...

Antiglycation of Insulin by Selected Six Bioactive Peanut Sprout Stilbenoids and Demonstration of Methylglyoxal‐Mediated Biphasic Insulin Glycation by O‐Phenylenediamine Derivatization

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Graphical abstract demonstrates 6 peanut sprout containing stilbenoids exhibiting varied structure‐activity potency in protection of insulin integrity from glycation mediated by methylglyoxal (MG), glucose and fructose. Meanwhile, MG‐mediated biphasic insulin glycation was evidenced in Tricine SDS‐PAGE analysis and supported by O‐phenylenediamine (OPD)

From Fish Waste to Stable Omega‐3 Bioactive Lipids: Encapsulation Strategies and a Conceptual Framework for Antioxidant and Antimicrobial Functional Food Fortification

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Fish waste is valorized into omega‐3‐rich bioactive lipids (EPA and DHA), followed by stabilization through advanced encapsulation technologies to prevent oxidation and improve storage stability. Encapsulation protects polyunsaturated fatty acids from oxidation, improves storage stability, enables controlled gastrointestinal release, and enhances ...

The Sensory, Chemical and Microbiological Quality of Sous‐Vide Cooked Sea Bass (Dicentrarchus labrax Linneaus, 1758) With Liquid Smoke Flavor

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
The processing of sea bass fillets, flavored with liquid smoke‐salt‐vegetable oil, using sous‐vide technology is an innovative method that both enhances organoleptic quality and ensures safe preservation. The fillets, which were flavored and vacuum‐sealed, were cooked at different temperatures and then transferred to cold storage following rapid ...

Biomarkers of DHA status

Prostaglandins, Leukotrienes and Essential Fatty Acids, 2009
Docosahexaenoic acid (DHA, 22:6n-3) is a long chain omega-3 fatty acid that is the primary n-3 fatty acid found in the central nervous system where it plays both a structural and functional role in cells. Because the tissues of interest are generally inaccessible for fatty acid analysis in humans and because precise DHA intake is difficult to determine,

Sex Differences in the Twenty-Four-Hour Mean Plasma Concentrations of Dehydroisoandrosterone (DHA) and Dehydroisoandrosterone Sulfate (DHAS) and the DHA to DHAS Ratio in Normal Adults*

The Journal of Clinical Endocrinology & Metabolism, 1980
The 24-h mean plasma concentrations of dehydroisoandrosterone (DHA) and dehydroisoandrosterone sulfate (DHAS) and the DHA to DHAS ratio were determined in 37 normal women, aged 21-75 yr, and 32 normal men, aged 21-72 yr. As predicted from our study of sex differences in the metabolism of DHAS, women showed a markely higher DHA to DHAS ratio than men at

Toxicology and safety of DHA

Prostaglandins, Leukotrienes and Essential Fatty Acids, 2009
Docosahexaenoic acid (DHA) is a long-chain polyunsaturated fatty acid with activities in both infants and adults. The objective of the current work was to evaluate the published literature concerning the toxicological assessment of DHA-rich oils in animals and the safety profile of DHA consumption in humans.
