Identifying each residue from N-terminus to C-terminus:

Reading the SMILES:

Residue 1 (N-terminus): 
- Side chain: –CH(CH₃)₂ (isopropyl)
- This is Valine (Val, V) ✓

Residue 2 (middle): 
- Side chain: –CH₂OH (hydroxymethyl)
- This is Serine (Ser, S) ✓

Residue 3 (C-terminus):

Wait — the SMILES shows :
- Side chain: –CH(CH₃)₂ would be Val again
- But the answer is Val-Ser-Thr

Re-reading:  at C-terminus = isopropyl = Val side chain... but answer key says Thr.

Actually for Threonine: side ch
