Urea, wanda kuma aka sani da urea ko carbamide, yana da charbus carbulu ch4n2o ko co (Nth2) 2. Ganyen kwayoyin, oxygen, da farin shaye shaye-shaye, da farin shaye-shaye, da kuma farin ciki. Daya daga cikin mafi sauki mahimmin kwayoyin shine babban samfurin enarfin metabolism mai dauke da kayan metabolism da bazawa a cikin dabbobi. A matsayin takin mai tsaka tsaki, urea ya dace da ƙasa da tsire-tsire. Abu ne mai sauki mu kiyaye, dacewa don amfani, kuma bashi da ƙarancin lalacewa a ƙasa. Yana da takin nitrogen na sinadarai tare da babban adadin amfani da mafi girman nitrogen. Urea ya hade karkashin wasu yanayi ta amfani da ammoniya da carbon dioxide a masana'antu.
Urea na iya amsawa tare da acid don samar da salts. Yana da hydrolysis. A yanayin zafi, halayen halayen za a iya za'ayi don samar da biuret, triuret, da cyanuric acid. Zafi zuwa 160 ℃ don bazawa, samar da iskar ammoniya gas kuma yana canza shi zuwa isocyanate. Domin wannan abu yana nan a cikin fitsarin ɗan adam, ana mai suna Urea.
