Molecular weights of special molecules?

Question

Can someone help me find the molecular weights of B Lymphocytes, Vaccine virus, gamma globulin, and ribozyme?

I can't find the molecular weights anywhere.

Thanks

Answer 1

That's because these biological materials are not all single molecules, per se. Many of them are complexes of macromolecules, so there's no specific material to determine a specific MW for.

But I'm a chemist, not a biologist, so I may be mistaken.

Answer 2

Those weights are so large as to be expressed not in amu, but kilodaltons (1 kd=1000amu). Keep looking. You will likely get approximate numbers, which vary with conformation and mutations.

Answer 3

You need correct chemical formulae for all of these. If & when you get those, you can calculate molecular weights with no problem.
