Uric acid waa badeecad dhexdhexaad ah oo dheef-shiid kiimikaad purine ah. Waxaa soo saaray oksaydhka xanthine by xanthine oxidase. Waa nooc ka mid ah oxypurine oo leh sifooyinka antioxidant. Inta badan xayawaanka dhulka, urate oxidase waxay kicin kartaa oksaydhka dheeraadka ah ee uric acid ilaa allantoin, laakiin hidda-wadaha urate oxidase ee bini'aadamka iyo qaar ka mid ah primates hore ma ciyaaraan door, sidaas darteed uric acid ma sii burburin doono jirka. Sababta ay shaqada urate oxidase u luntay habka horumarinta bini'aadamka ayaa weli ah su'aal la raadinayo. Astaamaha antioxidant-ka ee uric acid ayaa u horseeday cilmi-baarayaasha in ay qiyaasaan in isbeddelkan uu faa'iido u yeelan doono hore iyo bini'aadamka. Natiijooyinka daraasadaha ku saabsan la qabsiga noolaha ee jawiga sare waxay taageerayaan mala-awaalka ah in uric acid sida antioxidant-ka ay yareyn karto cadaadiska oksaydhka ee ay keento hypoxia sare. Tijaabooyin xayawaan ah oo ku saabsan cudurrada ay keento cadaadiska oksaydhisku, waxaa la ogaaday in uric acid ay ka hortagi karto ama yareyn karto cudurrada. Cilmi-baarayaashu waxay u sababeeyeen sifooyinka antioxidant ee uric acid. Natiijooyinka cilmi-baarista ee habka antioxidant-ka ee uric acid waxay sidoo kale taageertaa soo jeedintan.
Cudurka 'sclerosis', Gwen Scott wuxuu sharaxay muhiimada aysiidhka uric sida antioxidant loogu talagalay sclerosis badan. Heerka uric acid ee serumku waxa uu la xidhiidhaa dhacdooyinka sclerosis badan, sababtoo ah serum ee bukaannada sclerosis badan Heerka uric acid waa mid hooseeya, bukaanada leh gout waa dhif inay la kulmaan cudurkan. Waxa ka sii muhiimsan, uric acid waxa loo isticmaali karaa in lagu daaweeyo xasasiyada tijaabada ah ee cerebrospinal cerebrospinal {{2}model xoolaha ee sclerosis. Marka la soo koobo, inkasta oo habka uric acid sida antioxidant si fiican loo taageeray, sheegashada ah in heerka uric acid ee jidhku uu saameeyo khatarta sclerosis badan ayaa weli muran badan oo u baahan cilmi-baaris dheeraad ah.
Uric acid waxay leedahay xoogga ugu sarreeya ee dhammaan antioxidants dhiigga, iyo kala bar wadarta awoodda antioxidant ee serum aadanaha ayaa ka qaybqaatay. Hawlaha antioxidant ee uric acid waa mid aad u adag. Ma la falgali karto qaar ka mid ah oksaydhiyeyaasha sida superoxide, laakiin waxay saameyn antioxidant ku yeelan kartaa peroxynitrite, peroxide iyo hypochlorous acid.
