Abstract

: To investigate the effect of chlorogenic acid (CGA) on non-enzymatic glycation and oxidation of low density lipoprotein (LDL). : The non-enzymatic glycation incubation system of LDL-glucose was established. The contents of early glycation products (Amodori product) and intermediate products (dicarbonyl compound) were determined by ultraviolet-visible spectrophotometry, and the content of advanced glycation end products (AGEs) was determined by fluorescence spectrophotometry. The LDL oxidation incubation system was established. The contents of thiobarbituric acid reactive substances(TBARS) and conjugated diene were determined by ultraviolet-visible spectrophotometry. The tryptophan fluorescence quenching, and the content of lipofuscin, total fluorescence products, active aldehydes and malondialdehyde were determined by fluorescence spectrophotometry, and further verified by three-dimensional fluorescence spectroscopy. : In the LDL glycation experiment, 150 μg/mL and 300 μg/mL CGA inhibited the formation of Amadori product, dicarbonyl compounds and AGEs. In the LDL oxidation experiment, 15 μg/mL and 25 μg/mL CGA inhibited the formation of TBARS effectively; 5 μg/mL and 10 μg/mL CGA inhibited tryptophan fluorescence quenching, a...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
