Lysine and tryptophan are two amino acids that contain an additional N atom in the R group bonded to the α carbon. While lysine is classied as a basic amino acid because it contains an additional basic N atom, tryptophan is classied as a neutral amino acid. Explain why this difference in classication occurs.

Tyrosine is an amino acid whose side chain has a pKa of 10.1. At pH 7, what protonation form would you expect to find it in?
Consider the following tetrapeptide, written in a sequence according to normal convention, from left to right: Residue 1 is acidic; Residue 2 is cysteine (an amino acid containing a –CH2SH R-group); Residue 3 is proline (a large hydrophobic amino acid); Residue 4 is basic. Of the following four general statements, which one is TRUE regarding this tetrapeptide? This tetrapeptide does not have the ability to form a disulfide linkage with an identical tetrapeptide. Residue 2 belongs to the amino acid category known as "basic." 3 of these 4 responses are correct This tetrapeptide could be part of an alpha-helix, since the large size of the proline would not have any impact on the consistency of the spiral shape. The acidic residue (Residue #1) is at the amino terminus of this tetrapeptide.
