Determination of Significance:
Lipid Hydroperoxide (LPO) is a kind of peroxide produced by unsaturated fatty acid chain through the action of free radicals or reactive oxygen species. Under pathological conditions, the enhancement of lipid peroxidation can lead to the increase of LPO with low content. The increase of LPO content will damage the structure and function of cells. LPO content is closely related to the immune system and aging.
Measurement Principle:
LPO is heated under acidic conditions to produce malondialdehyde (MDA). MDA is condensed with thiobarbituric acid (TBA) to produce a brownish red substance named 3,5,5-trimethyloxazole-2,4-dione. Its maximum absorption wavelength is 532nm. The content of LPO in the sample can be estimated after colorimetry.
