Threo-L-Phenyserine is a threonine-derived, non-proteinogenic amino acid bearing a side chain that includes a benzyl-substituted hydroxyl-bearing phenyl group, classifying it as a β-hydroxy amino acid analogue. The molecule contains both an amino group and a carboxyl group, with stereochemistry specified as L and threo relative configuration, and the side-chain hydroxyl provides a polar functionality that can participate in hydrogen bonding and derivatization chemistry. As a stereochemically defined amino acid analogue, it is used in peptide and structure-activity studies where incorporation of a phenyl-substituted β-hydroxy residue is used to probe conformational effects, side-chain polarity, and synthetic accessibility of modified peptide architectures.
