Improved catalytic activity of ruthenium–arene complexes in the reduction of NAD+ [PDF]
, 2012 A series of neutral Ru-II half-sandwich complexes of the type [(eta(6)-arene)Ru(N,N')Cl] where the arene is para-cymene (p-cym), hexamethylbenzene (hmb), biphenyl (bip), or benzene (bn) and N,N' is N-(2-aminoethyl) -4-(trifluoromethyl)benzenesulfonamide (

Surface Fluorescence Studies of Tissue Mitochondrial Redox State in Isolated Perfused Rat Lungs [PDF]
, 2012 We designed a fiber-optic-based optoelectronic fluorometer to measure emitted fluorescence from the auto-fluorescent electron carriers NADH and FAD of the mitochondrial electron transport chain (ETC).

Determination of quantum yield of NADH and FAD in alcohol-water solutions: the analysis of radiative and nonradiative relaxation pathways [PDF]
arXiv, 2022 Combined studies on fluorescence quantum yield in coenzymes NADH and FAD in water-methanol, water-ethanol and water-propylene glycol mixtures and on time-resolved fluorescence of the same molecules under excitation at 450 and 355~nm by means of the TCSPC method have been carried out.

Thermodynamics drives coenzyme redundancy in metabolism [PDF]
, 2021 Coenzymes redistribute a variety of resources (e.g., electrons, phosphate groups, methyl groups) throughout cellular metabolism. For a variety of reactions requiring acceptors or donors of specific resources, there often exist degenerate sets of ...

Review on Microreactors for Photo-Electrocatalysis Artificial Photosynthesis Regeneration of Coenzymes [PDF]
Micromachines (Basel)In recent years, with the outbreak of the global energy crisis, renewable solar energy has become a focal point of research. However, the utilization efficiency of natural photosynthesis (NPS) is only about 1%. Inspired by NPS, artificial photosynthesis (

FEBS Letters, EarlyView.Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Whole blood NAD and NADP concentrations are not depressed in subjects with clinical pellagra [PDF]
, 2007 Population surveys for niacin deficiency are normally based on clinical signs or on biochemical measurements of urinary niacin metabolites. Status may also be determined by measurement of whole blood NAD and NADP concentrations. To compare these methods,
