Mr Rayon Posted June 1, 2009 Author Share Posted June 1, 2009 What is common to all proteins? All proteins contain carbon, hydrogen, oxygen and nitrogen. In addition to these, some also contain sulfur and phosphorus. How much of it would be found in a protein (at minimum)? I'm still not sure. I guess, C, H, O and N. But that still leaves B and D.
