Question

Tyrosine is one of the amino acids present in protein. Its content in protein is 0.22% and its molecular weight is . Lowest molecular weight of protein is:

Solution

Correct option is

82273

 

When molar mass is 100 then protein content is 0.22%

   Molar mass of protein

                             

                              = 82273.
