Acetyl-α-MSH (11-13)

Acetyl-α-MSH (11-13) is a minimal melanocortin fragment containing residues critical for aromatic stacking and charge distribution. The acetylation enhances conformational uniformity. Despite its size, it serves as a valuable model for studying ligand recognition. Applications include peptide motif mapping and structural analysis.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
