Xenobiotics sida daawooyinka synthetic, sunta dabiiciga ah iyo antibiotics waxaa detoxified by set of xenobiotic-metabolising enzymes. In aadanuhu, waxaa ka mid ah cytochrome P450 oxidases, UDP-glucuronosyltransferases, iyo glutathione S-transferases. Nidaamkan of enzymes ee saddexda marxaladood marka hore oxidizes xenobiotic (phase I) oo markaas isku xidha molecule biyaha lagu milmi karo (phase II). The xenobiotic biyo lagu milmi karo waxaa lagu soo saari karaa out of unugyada organic waxyeello iyo waxaa laga yaabaa in la soo saaro antioxidants badan oo ku jira unugyada iyo xitaa laga saaro xaaladaha oxidative ka hor inta aan la samaynta xaaladaha kuwan waxaa laga yaabaa in la wadaago by noocyo kala duwan oo ah xaaladaha oxidative iyo xaaladaha ku xiran sida xenobiyoid peroxides iyo xaaladaha ku xiran xaaladaha microbial.
