Quizplus · Accepted Answer

Amino acids that are not incorporated into polypeptides can serve various functions in the body, including being precursors to neurotransmitters (e.g., tryptophan to serotonin), acting as methyl donors in various biochemical reactions, being modified into antibiotics by certain organisms, and influencing blood flow through their metabolites. Therefore, all the options listed are correct applications or transformations of amino acids outside of their role in protein synthesis.
