Lipid peroxidation
- Refers to Chain reaction providing a continuous supply of free radical that initiates further peroxidation.
- Whole process is given below:
- Initiation:
X’ + RH —> R’ + XH
- Propagation:
R’ + O2 —> ROO’
ROO’ + RH –> ROOH + R’
- Termination:
ROO’ + ROO’ —> ROOR + O2
ROO’ + R’ —> ROOR
R’ + R’–> RR
