The formula that represents a protein is compound

A. C18H32O2

B. C58H114PNO8

C. C600H1000O500

D. C708H1130N180O224S4

 

 

The answer is D. Please explain why B is not a good answer.

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)?

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.

hint: protiens are massive, often containing thousands of atoms.

Hint2: How many C H O and N are, at minimum, found per amino acid?

Hint 3: Which of the 20 naturally synthesised amino acids contain phosphorus?

Well, the question does not exclude modifications.
