FAD (flavin adenine dinucleotide)

an electron carrier similar in action to NAD, picking up hydrogen from succinic acid (succinate) in the KREBS CYCLE. The hydrogen is transported to the mitochondrial cristae where it enters an ELECTRON TRANSPORT SYSTEM at a lower point than NAD, with the release of only two molecules of ATP (rather than three ATP molecules when NAD is the carrier).

Academics are wont to look down on local historians, to regard them as a bunch of well- meaning amateurs and antiquarians, a motley collection of autodidacts and fixated faddists. Today, local historians have the capacity to self-publish their output; but no amount of eye catching layout and scanned pictures will lend quality and depth to a meaningless text.
