Term Name:	'de novo' NAD+ biosynthetic process from L-tryptophan
Synonyms:	'de novo' NAD biosynthetic process from L-tryptophan, 'de novo' NAD biosynthetic process from tryptophan, de novo NAD biosynthetic process from tryptophan
Definition:	The chemical reactions and pathways resulting in the formation of nicotinamide adenine dinucleotide (NAD+), beginning with the catabolism of L-tryptophan into the precursor quinolinate. NAD+ is a coenzyme that interconverts with its reduced form, NADH, in many redox and catabolic reactions.
