Scopolamine is a competitive, non-selective muscarinic receptor antagonist drug acetylcholine receptor antagonist (mACHR) giving rise to important pharmacological effects, such as by example antispasmodic action in the gastrointestinal tract. Answer: 13) Briefly explain, in text, the reactions necessary for the biosynthesis of scopolamine from the litorine.arrow_forward
