COMPARATIVE STUDY OF CARBON PASTE ELECTRODES (EPK) AND MODIFIED CARBON PASTE ELECTRODES

Uric acid (2,6,8-trioxypurin) is the final metabolic result of purine nucleotides, which will be excreted in the urine. Purines are a nucleoprotein group that comes from food and the destruction of old body cells. Excess uric acid in the body shows symptoms of several diseases such as diabetes, hi...
