Surface Forms

nicotinamide adenine dinucleotides plural

Morphology

nicotinamide + adenine + dinucleotide

The term is a systematic chemical name: knowing 'nicotinamide', 'adenine' and 'dinucleotide' lets a learner infer it is a dinucleotide molecule containing nicotinamide and adenine units. However, the detailed biological role (coenzyme/signalling and regulation of DNA repair, gene expression, ageing) is specialist knowledge not predictable from the constituents, so the composition is clear but the functional meaning is only partially accessible.

Etymology

Nicotinamide adenine dinucleotide shows its parts: nicotinamide, adenine, and dinucleotide meaning two small blocks joined, so the name helps you remember it is a small molecule used in many cell tasks. Because of its parts and shape, it acts as a 'signal' that helps control DNA 'repair' and other processes linked to 'ageing'.
