알란토인(영어: allantoin)은 화학식 C4H6N4O3의 화합물이다. 5-우레이도히단토인(5-ureidohydantoin) 또는 글리옥실디우레이드(glyoxyldiureide)라고도 한다. 글리옥실산의 이유화물이다. 알란토인은 동물, 식물, 박테리아를 포함한 대부분의 유기체에서 주요 대사 중간체이다. 이는 요산산화효소(uricase)의 작용에 의해 핵산의 분해산물인 요산으로부터 생산된다. 이는 천연 미네랄 화합물(IMA 기호 Aan)로 발생한다.

역사

알란토인은 1800년 이탈리아 의사 미셸 프란체스코 부니바(Michele Francesco Buniva, 1761~1834)와 프랑스 화학자 루이니콜라 보클랭에 의해 처음 분리되었다. 그들은 알란토인이 양수에 존재한다고 잘못 믿었다. 1821년에 프랑스의 화학자 장 루이 라세뉴(Jean Louis Lassaigne)는 알란투아액에서 이를 발견했다. 그는 그것을 "l'acide allantoique"라고 명명했다. 1837년 독일의 화학자 프리드리히 뵐러유스투스 폰 리비히요산으로부터 이를 합성하고 이름을 "알란토인"으로 바꿨다.
