Tropine
Definition:
(n.) A white crystalline alkaloid, C8H15NO, produced by decomposing atropine.
Example Sentences:
(1) Our findings indicate that endothelial receptors are characterised by a high affinity for scopolamine, which possesses a scopine base, and that muscle binding sites have a high affinity for antagonists possessing a tropine base (atropine, homatropine).
