Thematic Review Series: Living History of Lipids The arachidonic acid monooxygenase: from biochemical curiosity to physiological/pathophysiological significance

open access: yesJournal of Lipid Research, 2018
The initial studies of the metabolism of arachidonic acid (AA) by the cytochrome P450 (P450) hemeproteins sought to: a) elucidate the roles for these enzymes in the metabolism of endogenous pools of the FA, b) identify the P450 isoforms involved in AA ...

How does NO activate hemeproteins? [PDF]

open access: yesFEBS Letters, 1994
NO was reported to activate guanylate cyclase and, recently, prostaglandin H synthase. NO interaction with the heme component in different hemeproteins is determined by ligand property, electronic configuration of the heme iron and the specific effects contributed by the protein structure.

Recent advances in column coatings for capillary electrophoresis of proteins [PDF]

open access: yes, 2017
Capillary coatings effectively improve the separation performance of proteins in capillary electrophoresis, mainly by reducing protein adsorption onto the inner capillary wall and by regulating the electroosmotic flow (EOF) to accommodate the separation ...

Heme on innate immunity and inflammation

open access: yesFrontiers in Pharmacology, 2014
Heme is an essential molecule expressed ubiquitously all through our tissues. Heme plays major functions in cellular physiology and metabolism as the prostetic group of diverse proteins.

Fast ferrous heme-NO oxidation in nitric oxide synthases. [PDF]

open access: yes, 2009
International audienceDuring catalysis, the heme in nitric oxide synthase (NOS) binds NO before releasing it to the environment. Oxidation of the NOS ferrous heme-NO complex by O2 is key for catalytic cycling, but the mechanism is unclear.

Oxidation of Native and Modified Hemoglobin and Myoglobin by Sodium Nitrate. Effect of Inositol Hexaphosphate [PDF]

open access: yes, 1981
Native and modified hemoglobin, myoglobin and a and phemoglobin subunits were oxidized by sodium nitrite at pH 6. The experiments were carried out under oxy and deoxy conditions with and without inositol hexaphosphate (IHP).

Acetylated Epigallocatechin Gallate and Ascorbyl Palmitate: Comparative Study on Antioxidant Activity and Retardation of Lipid Oxidation in Fish Mince and Shrimp Oil

open access: yesJournal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT Antioxidant activities of acetylated epigallocatechin gallate (A‐EGCG) and ascorbyl palmitate (AP) were compared using different in vitro assays and food model systems. Both A‐EGCG and AP exhibited DPPH and ABTS radical scavenging activities and reducing power. AP demonstrated greater scavenging efficacy toward both radicals than A‐EGCG (p < 0.
