Explanation:
Proteins are actually polypeptide chains of amino acids(monomers).
)
So as we can see in the above figure that amino acid contain hydrogen, carbon, nitrogen and oxygen as essential elements. And R is variant which means that amino acids could be very diverse depending upon the nature of
As in case of methionine and cysteine amino acids, the variant side chains R contain sulfur.
)
And as far as phosphorus is concerned then it's found only in some proteins which are subject to post translational modifications, such as phosphorylation.
