(1) When oxygen ( O2 ) breathed in through the lungs oxidizes food taken by mouth, it is reduced by the food and produces active oxygen O2- ( superoxide anion radical ).

(2) O2- is further reduced by hydrogen atom H ( active hydrogen radical ), producing active oxygen H2O2 ( hydrogen peroxide ).

(3) H2O2 is further reduced, producing active oxygen HO・（ hydroxyl radical ） and hydroxide anion ( HO- )．

(4) HO・ is reduced by hydrogen atom, producing water ( H2O )

(5) HO- is also reduced by proton ( H+ ), producing water. CONCLUSION Oxygen from the lungs keeps producing active oxygen species ( O2-, H2O2, HO・) in the body, but these kinds of active oxygen species are reduced successively through bonding with atomic hydrogen (active hydrogen ) and eventually revert back to the original water. （

1. O2 ＋ e- → O2-
2. O2- ＋ H・ ＋ H+ → H2O2
3. H2O2 ＋ e- → HO・ ＋ HO-
4. HO・ ＋ H・ → H2O
5. HO- ＋ H+ → H2O
