Visualize hydrophobic and hydrophilic regions across a peptide sequence. Choose from multiple hydrophobicity scales and adjust the sliding window to explore local properties.
Odd number, 3-21
About this tool
Hydrophobicity is calculated using a sliding window average across the sequence. The Kyte-Doolittle scale is the most widely used for predicting transmembrane domains and surface-exposed regions. Hopp-Woods emphasizes hydrophilic regions (antigenic sites). Eisenberg is optimized for detecting amphiphilic helices. The GRAVY score is the mean hydrophobicity of all residues.
