Determination of triglycerides with special emphasis on biosensors: a review.
Triglycerides (TG) are transesterification product of fatty acids and glycerol and engaged in the transportation of fats. Elevated triglyceride level is associated with coronary heart disease (CAD), atherosclerosis and hypolipoprotenemia. Convenient and reproducible assay systems based on enzymes are an attractive alternative to conventional analytical methods. Triglyceride biosensors (TGBs) are based on either measurement of oxygen consumed or electron generated from splitting of H2O2, an ultimate product, of immobilized enzymes. TGBs work optimally within 2-900 s, between pH 6.4-8.5 and the potential 0.5-4V. TGBs measure TG level in serum directly and can be used over a period of 14 to 168 days. This review describes the analytic characteristics of various methods available for determination of TGs with special emphasis on TGBs.
