After a polypeptide chain has been synthesized, certain amino acids in the peptide may become modified. For each modified amino acid, identify the standard amino acid from which it is derived. Enter the unabbreviated name of the standard amino acid. ОН standard amino acid: "NH,-CH,-с-CH—CH,-ҫн—соо- H $HN. Identify the modification that yields the first amino acid depicted N'н. -—Р—0—CH, —сH—со- standard amino acid: Identify the modification that yields the second amino acid depicted.
