Urea - Wikipedia

L'urea (urèa o ùrea) è un composto chimico di formula CO(NH 2) 2 e massa molare 60,06 g/mol; in condizioni normali si presenta come un solido cristallino incolore; si tratta della diammide dell'acido carbonico. In tutti i tetrapodi, con l'eccezione degli uccelli e di alcuni rettili, è la sostanza tramite la quale vengono eliminati dall'organismo i prodotti azotati del metabolismo
