<prompt> Penicillin is the metabolic product of ?Aminoadipic acidAminocaproic acidLevulinic acidArachidonic acid  <response>: Ans. is a i.e., Aminoadipic acid Penicillin is a product of secondary metabolic pathway of Penicillium chrysogenum. a-aminoadipic acid is the precursor of penicillin. This compound is normally conveed to lysine primary metabolic pathway. However, when the growth of fungus is inhibited, a-aminoadipic acid is conveed to penicillin secondary metabolic pathway.
