Identify the following amino acids and their following side chain.
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”)

The common amino acids are polyprotic acids. All amino acids contain an amino group and a carboxyl group. Some amino acids contain ionizable side chains. The presence of an ionizable side chain creates a third ionizable group. For a diprotic amino acid such as glycine (structure shown below), three forms are possible. These forms, the fully protonated (AA*), single deprotonated (AA°), and completely deprotonated (AA) exhibit different acid-base properties. NH;+ NH,+ NH, Neutral H,A (AA+) A- (AA•) (AA-) The Ka describing the AA* and the AA° equilibrium is 4.57 x10-3, while the Ka involving AA° and the anionic form AA- is a much smaller 2.51 x 10-10, The neutral form, AA° is referred to as isoelectric glycine. All amino acids can assume the isoelectric form under proper conditions. a. Calculate the pH of a 0.1 M solution prepared from the salt glycine hydrochloride (hint: use ICE table).
