Co-enzyme NADH is an electro active material, has two polarographic waves at
(+0.244V,+0.464V) by (HDME) including (DPP) in pH = 7.4 and T = 370 C, from
the different measurements to optimize the ideal conditions for its Polarographic
measurement. The acidity function was studied and found it’s inversely
proportional with (E1\2) and directly with (id) . The building standard calibration
curve is Shown that diffusion current consider as function to concentration
according to Ilkovic equation (id = k C). The study formation of molecular
complexes found that (Ub0) has shift E1\2 of NADH to high value by (+0.012V), but
the other substances have’s shift to less value by ( -0.012, -0.008, -0.007V)
for(ATP,Caff.,Vit.C)respectively, from calculation(kr

equal to (0.96, 35.3, 3.4, 3.0) as well (G

) values are(+0.1,-9.1,-3.1,-2.8) for(Ub0,ATP,Caff.,vit.C) respectively, found (ATP) complex formation is more stable
