Polyhydroxybutyrate PHB oo leh CAS 26744-04-7
PHB waxaa soo saara sheyga yar yar, oo sida muuqata ka jawaabaya xaaladaha diiqada jireed. Inta badan waa xaalad nafaqo xaddidan. polymerka ugu horrayn waa wax soo saarka kaarboonka (laga bilaabo gulukoosta ama istaarijka) waxaana u isticmaala nooleyaal sida nooc ka mid ah unugyada kaydinta tamarta ee dheef-shiid kiimikaadka marka ilo kale oo tamarta caadiga ah aan la heli karin.
