Triglycerides Reagent Kit (Glycerol-3-Phosphate-Oxidase Method) for Quantitative Determination

Triglycerides are fatty acid esters of glycerol synthesized by liver cells. They serve as a primary energy source for the body and are transported by lipoproteins. Abnormal triglyceride levels are a significant risk factor for coronary artery disease and peripheral vascular disease. Increased concentrations can also be found in conditions such as diabetes, liver disease, hypothyroidism, and nephritic syndrome. Conversely, decreased concentrations may indicate malnutrition or hyperthyroidism.

This reagent kit employs a robust enzymatic method based on Glycerol-3-Phosphate-Oxidase (GPO). The determination of triglycerides involves a series of enzymatic reactions: first, lipoprotein lipase splits triglycerides into glycerol and fatty acids. The glycerol is then phosphorylated by glycerokinase to glycerol-3-phosphate. In the next step, GPO oxidizes glycerol-3-phosphate, producing hydrogen peroxide (H2 O2 ). Finally, the H2 O2 reacts with 4-aminoantipyrine and 4-chlorophenol, catalyzed by peroxidase, to form a colored quinoneimine indicator. The photometric measurement of this colored compound is directly proportional to the triglyceride concentration in the sample. This enzymatic, endpoint method provides high accuracy and ease of use for clinical laboratories, hospitals, and diagnostic centers.
