Heavy Metal-Induced Inhibition Of Enzymatic Activity In Hen Egg White Lysozyme

Abstract:

Methods: In this study, we have determined the content of Cr, Ni, Cd, B, Hg, and Pb in chicken hen eggs using absorption atomic (AA) method. The residual enzymatic activity of HEWL, HEWL was evaluated using spectrophotometric method. Results: The levels of Cr, Ni, Cd, B, Hg, and Pb in hen eggs were 1.8300, 1.1300, 0.5350, 0.5200, 0.0025, and 0.0021 mg/kg, respectively. The inhibition of enzymatic activity of HEWL, by exposure to heavy metals was studied. We found that Cr, Ni, Cd, B, Hg, and Pb produced a loss of enzymatic activity.
