L-norleucine is a non-proteinogenic L-alpha-amino acid comprising hexanoic acid carrying an amino group at C-2. It does not occur naturally. It is a 2-aminohexanoic acid and a non-proteinogenic L-alpha-amino acid. It is a conjugate acid of a L-2-aminohexanoate. It is an enantiomer of a D-norleucine. It is a tautomer of a L-2-aminohexanoic acid zwitterion
An unnatural amino acid that is used experimentally to study protein structure and function. It is structurally similar to METHIONINE, however it does not contain SULFUR.
