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