Leu-Pro-Ala-NH2
Leu-Pro-Ala-NH2 is a simple tripeptide with a free amine group at the C-terminus. It consists of leucine (Leu), proline (Pro), and alanine (Ala) residues. The -NH2 at the C-terminus indicates that the peptide has a free amine group, which can be utilized for further reactions or modifications. This peptide sequence is used to study the effects of leucine, proline, and alanine in peptide structures and interactions, with potential applications in understanding peptide conformations or biological activities. Alternative Names: LPA; H-Leu-Pro-Ala-NH2; (S)-1-(L-Leucyl)-N-((S)-1-amino-1-oxopropan-2-yl)pyrrolidine-2-carboxamide. Grades: ≥95%. Molecular formula: C14H26N4O3. Mole weight: 298.39.
