obsolete NAD biosynthesis via nicotinamide riboside salvage pathway

OBSOLETE. The chemical reactions and pathways resulting in the formation of nicotinamide adenine dinucleotide (NAD) from the nicotinamide riboside (NR).

NAD biosynthetic process via the salvage pathway

Any process that generates nicotinamide adenine dinucleotide (NAD) from vitamin B3 derivatives, including nicotinic acid (NA) and nicotinamide (NAM), or from beta-nicotinamide D-ribonucleotide (NMN), nicotinamide riboside (NR) or nicotinate riboside (NAR), without de novo synthesis.
