In the body, reactive oxygen species cause various types of damage like lipid peroxidation and cellular damage.
Previous studies have stated that nicotine, which is the main component of tobacco, accelerates lipid peroxidation and thus induces atherosclerosis and predisposes to coronary artery disease (CAD).
To demonstrate lipid peroxidation in mice liver, extract - sodium nitroprusside (5uM) or ferrous sulphate (10uM) was introduced to produce thiobarbituric acid reactive species (TBARS).
The researchers tracked a number of indicators of aging, including glutathione (GSH) content in the brain and liver, lipid peroxidation, and protein responses.
In conclusion, it was supposed that elevation in serum ADA activity was due to cell mediated immune system stimulation by Mycobacterium avium subsp and the increase in MDA level might be due to the increase in lipid peroxidation because of affected membrane lipids by infection.
Blood samples were collected at different time points of ischemia and reperfusion, for malondialdehyde (MDA) evaluation as an index of lipid peroxidation, for total and LDL cholesterol determination and for evaluation of oxidized LDL
ROS cause lipid peroxidation of the cell membranes, which becomes less flexible and can be ruptured easily.
It is a radical scavenger [2, 3] and is an important sequence breaking antioxidant which inhibits lipid peroxidation by reducing singlet oxygen [4].
ABSTRACT The present study investigated whether an acute temperature change affected hemolymph antioxidant enzyme activities and lipid peroxidation in ark shell Scapharca subcrenala transferred from 22[degrees]C to 17[degrees]C, 27[degrees]C, and 32[degrees]C for 72 h and then transferred back quickly to 22[degrees]C for a 6-h recovery period.
Moreover, lipid peroxidation is one of the most unwanted effect of these ROS; during lipid peroxidation toxic products are formed.
These process lead to ultimately increased peroxidation of unsaturated lipids of the membrane.
