CharonY Posted June 1, 2009 Posted June 1, 2009 Moved to homework. Take a look at the elements in it. What is common to all proteins? How much of it would be found in a protein (at minimum)?
Mr Rayon Posted June 1, 2009 Author Posted June 1, 2009 CharonY said: What is common to all proteins? All proteins contain carbon, hydrogen, oxygen and nitrogen. In addition to these, some also contain sulfur and phosphorus. CharonY said: 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.
insane_alien Posted June 1, 2009 Posted June 1, 2009 hint: protiens are massive, often containing thousands of atoms.
CharonY Posted June 1, 2009 Posted June 1, 2009 Hint2: How many C H O and N are, at minimum, found per amino acid?
