the aerobic oxidation of r- is a free radical chain reaction which is initiated by peroxidase and propagated by r because ( a ) r-r , reasonably , must arise as 2r leads to r-r , ( b ) over 90 % of the enzyme-initiated reaction occurs free in solution , and ( c ) the km value for r- is independent of the type of initiator .
