Accession:PW:0000219 term browser browse the term
Definition:Those metabolic reactions involved in the synthesis of nicotinamide adenine dinucleotide (NAD). NAD can be synthesized de novo downstream of kynurenine metabolism of tryptophan degradation, or from precursors such as nicotinamide, nicotinic acid or nicotinamide riboside, collectively known as vitamin B3 or niacin.
Synonyms:exact_synonym: NAD biosynthetic pathway
 related_synonym: NAD biosynthetic process
