Linea 34:
=== Status oxydativus et reductus ===
Coniunctio inter [[nicotinamidum]] et [[ribosum]] haud stabilis sed valde utilis est: Causa [[electron]]a transferendi nicotinamidi adeninique dinucleotido duae formae sunt: oxydata, NAD<sup>+</sup>+H<sup>+</sup>+2e<sup>-</sup>, materia oxydans et forma reducta, NADH, materia reducens, electrona dans. NADH forma quasi onerata electron iuxta atomum nitrogenii anuli [[pyridinum|pyridini]] (quod nicotinamido inest).
* NAD<sup>+</sup> est forma oxydata, et nitrogenio anuli pyridini electron deest (igitur N<sup>+</sup> positive oneratum). Sub ''reductione'', electron (+ H<sup>+</sup>+e<sup>-</sup> stabilitate anuli dicti causa) accipens, NADH oritur, substratum (i.e. compositum alterum) reactionis chemicae oxydatur (effectus NAD<sup>+</sup> oxydans).
* NADH est forma reducta. Sub ''oxydatione'' NAD<sup>+</sup> oritur, atque unum ion hydrogenii (H<sup>+</sup>) et duo electrona (2e<sup>-</sup>) liberantur, "dantur", simul compositum substratum reducitur (hinc natura NADH reducens).
