A purified cytochrome protein was found to contain 0.376 % iron. What is the minimum molecular mass of the protein?

A

`14,800 u`

B

`1480 u`

C

`148,000 u`

D

`148 u`

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of iron (minor component) per gram of protien `=(0.376)/(100)=0.00376g`
Atomic mass of iron = 56 u
Minimum molecular mass
`=("Atomic mass of Fe")/("Mass of Fe per gram of macromolecule")`
`(56)/(0.00376)=14,800 u`
