(d) C, H, O, S, and l​

Answer 1

most naturally occurring proteins are:

C,H,O,P,and S

Answer 2

The five elements present in most naturally occurring proteins are (a) C, H, O, P, and S.

Explanation:

• Proteins are basically long chains of amino acids held together by a connection called polypeptides. The elements which form these acid chains are carbon, hydrogen, oxygen, nitrogen, and sulfur.

• Some elements that help form amino acids are inside the body, and some other amino acids are in taken through food. These elements include histidine, isoleucine, lysine, etc.

• These peptide bond molecular weight ranges from 5000 to 1,000,000. The negative charges around them are delocalized through a process known as resonance.
