001) (Tables 1 and 2) in smokers as compared to non-smokers in the control group as well as in the patient group, indicative of enhanced lipid peroxidation in smokers.
Their scavenging activity on DPPH, reducing power and total phenolic contents were also determined which had shown high antioxidant activity and the order of their antioxidant activity was found same as for lipid peroxidation inhibitory effect.
6] As lipids undergoing peroxidation are metabolized by this enzyme, the accumulation of lipid peroxides is prevented in both HDL and LDL.
This increase suggested that it can be a defense mechanism against increased free radicals together with lipid peroxidation.
1998) and the neutral fraction (NMF) enriched in phytosterol-like compounds, reduce the infarct size in both normal and cholesterol fed animals in vivo, 2) to evaluate the potential antiatheromatic activity by histopathological examination and 3) to evaluate the potential activity of both extracts against lipid peroxidation and LDL oxidation.
Peroxidation of these PUFAs of the cell membrane by the free radicals, especially by the ROS, ultimately leads to the loss of fluidity of the cell membrane.
As compared to other antioxidative agents which prevent the establishment of lipid peroxidation, beta-carotene traps free radicals and thus stop chain reaction.

Tomato lycopene has the competency to reduce the risk of lipid peroxidation in the blood flow.
A chain reaction initiates the damaging effect of the process which provides continued supply of free radicals which in turn causes further peroxidation.
Moreover, we determined the effect of the phenolic extract on a nonenzymatic lipid peroxidation in resting blood platelets and enzymatic lipid peroxidation, arachidonic acid metabolism (measured by the level of thiobarbituric acid reactive substances (TBARS)), in blood platelets activated by thrombin (as a strong physiological agonist).
