ʻO ka Azetidine he mea'enelea heterocyclic i hoʻohuiʻia i loko oʻekolu mau carbon carbon a hoʻokahi hoʻokahi amene. He wai i loko o ka lumi wela me kahi mea ikaika o ka amonia a he ikaika maoli ke hoʻohālikelikeʻia me nā amine lua.
ʻO ka azetidine a me kāna mau mea hoʻohālike, he mau kumu maʻamauʻole ia i nā huahana kūlohelohe. ʻO keʻano, he mau mea nui ia o nā mea'eneki me nā penaresidins. ʻO ka nui loa o ka azetidine i loko o ka waiwai maoli,ʻo ia ka azetidine-2-carboxylic acid, kahi homologinogenic homolog o proline.
