Before revision: The (L) carnitine is metabolized at its beta-hydroxy group by (L) carnitine dehydrogenase , which forms 3-Dehydrocarnitine , which then acts as an inducer for the enzyme, further allowing the enzyme to catalyze the reaction.
After revision: The (L) carnitine is metabolized at its beta-hydroxy group by (L) carnitine dehydrogenase ; the 3-Dehydrocarnitineand the coenzyme NAD+ forms 3-Dehydrocarnitine , which then acts as an inducer for the enzyme, further allowing the enzyme to catalyze the reaction.
