Percentage of Se in peroxidase anhydrase enzyme is 0.5% by weight (at. wt. = 78.4), then minimum molecular weight of peroxidase anhydrase enzyme is

Suppose the mol. wt. of enzyme = xIn 100 g of enzyme, wt. of Se = 0.5 g∴    In  x  g  of enzyme  wt.  of  Se=0.5100 × xHence  78.4   =  0.5 × x100∴   x=15680=1.568 ×  104
