Question

In the given pentapeptide, find out an essential amino acid (\(Y\)) and the sequence present in the pentapeptide.
 Choose the correct answer from the options given below:

• A. \(Y=\) Threonine;    Sequence: Thr–Ser–Asp–Gly–Ala
• B. \(Y=\) Serine;   Sequence: Ser–Asp–Thr–Ala–Gly
• C. \(Y=\) Serine;    Sequence: Thr–Ser–Asp–Ala–Gly
• D. \(Y=\) Threonine;  Sequence: Ser–Thr–Asp–Gly–Ala

Hint:

Always read peptide sequences from the \(\mathrm{NH_2}\) (N-terminal) end and identify amino acids by their side chains.

Answer 1
