Many bioactive compounds are derived from amino acids. This compound, found in trace amounts in mammalian brains and hypothesized to play a role as a neuromodulator or neurotransmitter, is derived from an amino acid through removal of the backbone carboxylic acid group. The amino acid from which it is derived must be: (Write out the entire name; Spelling matters, but case does not; Do not include L- or D- in the name; For acidic amino acids write the full name, e.g. “so-and-so acid”)
Determine the net charge of the peptide below at pH 7 and 12. Show your solution. Thr-Glu-Pro-Ile-Val-Ala-Pro-Met-Glu-Tyr-Gly-Lys
Millon's test is used to detect the amino acid, tyrosine. However, why is it not recommended to solely use the qualitative test to determine the presence of this specific amino acid residue? O This is because the test will yield a positive result for any compound that has a phenol structure. O This is because the test will yield a positive result only for acidic amino acids. O This is because the test will yield a positive result for all amino acids. O This is because the test will yield a positive result for all aromatic compounds.
