The stabilization of a radioactive parent element into a stable daughter element occurs through the process of radioactive decay. The unstable atomic parent emits radiation and loses its energy. This leads to the formation of a daughter element, which is less radioactive or is stable.
        
                    
             
        
        
        
I believe the appropriate answer is, short amino acid chains, NAG, NAM, and some lipid proteins.
Peptidoglycan is also known as Murein, it is a polymer consisting of sugars and amino acids that form a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consist of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM),
