試題詳解

28. A teacher allocates 4 peptides (peptide sequences shown below) to five students: Samuel, John, Eric, Emma, and Ramus (There are two students getting the same peptide).

Peptide 1: AKLFPIEARGQA； Peptide 2: CYTTLNKTG；

Peptide 3: GTGPPSGNP； Peptide 4: ASQHPMLWR

Samuel says: All the residues in my peptide have only one chiral center.

John says: My peptide contains many residues which do not favor α-helix structure.

Eric says: My peptide does not contain the residue which can be O-glycosylated.

Emma says: My peptide can be cleaved into two peptide fragments by trypsin.

Ramus says: My peptide does not contain any aromatic ring.

Please answer which description is correct:
(A) Ramus and Eric get the same peptide.
(B) Samuel gets peptide 3 and Emma gets peptide 2.
(C) John and Emma get the same peptide.
(D) John and Ramus get the same peptide.
(E) Eric gets peptide 1 and Samuel gets peptide 2.
