From: Nicotinamide adenine dinucleotide reduced (NADH) is a natural UV filter of certain bird lens
(a) UV–Visible spectra of bird lens metabolomic extracts in aqueous solution and the spectrum of 0.08 mM NADH aqueous solution; (b) Optical absorption spectra of NADH, NAD + and KN; (c) Kinetics of NADH fluorescence decay (green dots), measured at λem = 460 nm, convolved with IRF (black dots) and fitted by a biexponential function (black line); insert: a steady-state fluorescence spectrum of NADH; (d) Kinetics of NADH photodecomposition (in units of number of molecules in 3 mL of aqueous solution) during 300–400 nm photolysis under Ar and O2 with the correction on the solvent evaporation during the experiment.
