In the context of the Antioxidant activity, based on different activities such as DPPH, NO, and FRAP etc ... different reactions were involved. When exactly radical quenching will take place and when radical scavenging will take place. What is the difference?
Can someone pls clarify my doubt.
Free radical is defined by the occurrence of an unpaired electron in an organic molecule or metal. This potentially unstable electronic configuration can react either to acquire or to lose an electron and form a more stable product. Free radicals have the potential to serve as either effective oxidants or reductants while Free radical quenching can be defined as any reaction in which the free radical forms products that are not free radicals.
I hope this information is helpful.
There is no difference, its just terminology, "scavenging" is more common (popular)
Wow!! Fantastic information i got today from all respected Usama Ramadhan sir, Oluwaseun Ruth Alara madam , Farukh Sharopov sir and Olusegun Abayomi Olalere sir. Thank You for all answers.
But if quenching is reversiable, how the terminology will be same Farukh Sharopov sir.
maybe the question about "what is different ?" is done, but the "question: When exactly we determine its radical quenching, and when we determine its radical scavenging"
Antioxidant scavenger makes the free radical less reactive
Antioxidant quencher completely neutralizes the free radical
so, radical scavenger results in another free radical and radical quencher produces stable molecules
