Nicotinamide (Vitamin B3) Deficiency in Follicular Fluid of Patients With Ovarian Ageing
Journal of Cellular and Molecular Medicine, Volume 30, Issue 6, March 2026.ABSTRACT Nicotinamide is an essential precursor of NAD involved in energy metabolism. A decline in NAD levels across tissues during ageing is well‐documented, and NAD metabolism has been implicated in ovarian ageing. We investigated the relationship between ovarian ageing and the levels of nicotinamide (NAM) and its metabolite 1‐methylnicotinamide (MNA)

Physiological Evidence for Isopotential Tunneling in the Electron Transport Chain of Methane-Producing Archaea [PDF]
, 2017 Many, but not all, organisms use quinones to conserve energy in their electron transport chains. Fermentative bacteria and methane-producing archaea (methanogens) do not produce quinones but have devised other ways to generate ATP. Methanophenazine (MPh)

Nickel ions induced substrate inhibition for D-amino acid oxidase [PDF]
The effect of Ni ions on the structure and activity of D-amino acid oxidase (DAAO) was investigated at pyrophosphate buffer, 37 Centigrade. The activation and inhibitory concentration ranges of Ni (II) on DAAO were also determined.
