Valproic acid sketchy.
Intermediate 4-ene-valproic acid synthesis by CYP2A6 and CYP2C9, as well as to a smaller level by CYP2B6 is the most important group of Valproic acid pathways that are controlled by CYP. These metabolizing enzymes also play a role in the conversion of valproic acid into inert 4-OH-valproic acid and 5-OH-valproic acid.
