Chemistry Question on Some basic concepts of chemistry
Percentage of Se in peroxidase anhydrous enzyme is 0.5% by weight (at. wt = 78.4) then minimum molecular weight of peroxidase anhydrous enzymes is
A
1.568 × 10^4
B
1.568 × 10^3
C
15.68
D
2.136 × 104
Answer
1.568 × 10^4
Explanation
Solution
In peroxidase anlydrous enzyme 0.55 Se is present means, 0.5gm. Se is present in 100gm of enzyme In a molecule of enzyme one Se atom must be present hence 78.4 gm Se will be present in 0.5 100 × 78.4 = 1.568 × 104
