Consider the following tetrapeptide, written in a sequence according to normal convention, from left to right: Residue 1 is acidic; Residue 2 is proline (a large hydrophobic amino acid); Residue 3 is cysteine (an amino acid containing a -CH2SH R-group); Residue 4 is basic. Which of the following four general statements is TRUE regarding this tetrapeptide? This tetrapeptide probably is not part of an alpha-helix, since the large size of the proline would disrupt the consistency of the spiral shape. Residue 3 belongs to the amino acid category known as "basic." This tetrapeptide has the ability to form a disulfide linkage with an identical tetrapeptide. The acidic residue (Residue #1) is at the amino terminus of this tetrapeptide. 3 of these 4 responses are correct
