Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Separating NADH and NADPH fluorescence in live cells and tissues using FLIM. [PDF]

, 2014
NAD is a key determinant of cellular energy metabolism. In contrast, its phosphorylated form, NADP, plays a central role in biosynthetic pathways and antioxidant defence.

NADH/NADPH bi-cofactor-utilizing and thermoactive ketol-acid reductoisomerase from Sulfolobus acidocaldarius

, 2018
Ketol-acid reductoisomerase (KARI) is a bifunctional enzyme in the second step of branched-chain amino acids biosynthetic pathway. Most KARIs prefer NADPH as a cofactor.

Conversion of volatile aldehydes to their corresponding alcohols in the presence of NADPH or NADH.

, 2012
Arabidopsis (No-0) leaves were disrupted completely in the absence (control, white bars) or presence of NADH (+NADH, shaded bars) or NADPH (+NADPH, black bars), and the volatile compounds that formed were analyzed.

Flow Cytometric Assay of Cytochemically Demonstrated NAD(P)H Oxidoreductase (Diaphorase) Activities

, 1998
The tetrazolium salt 5-cyano-2,3-di- p-toluyl-tetrazolium chloride (CTC), yielding a fluorescent formazan on reduction, was used to measure NAD(P)H oxidoreductase activity.

Vascular NADH/NADPH oxidase is involved in enhanced superoxide production in spontaneously hypertensive rats [PDF]

, 2000
This study was designed to test the hypothesis that stimulation of nicotinamide adenine dinucleotide/nicotinamide adenine dinucleotide phosphate (NADH/NADPH) oxidase is involved in increased vascular superoxide anion (*O(2)(-)) production in ...

Switching Cofactor Dependence of 7β-Hydroxysteroid Dehydrogenase for Cost-Effective Production of Ursodeoxycholic Acid

, 2018
Dehydrogenases are widely employed as biocatalysts for the production of optically pure chemicals under mild conditions. Most dehydrogenases are nicotinamide cofactor (NADPH or NADH)-dependent oxidoreductases. 7β-Hydroxysteroid dehydrogenase (7β-HSDH) is
