Sequence Input
Paste a one-letter amino-acid sequence or FASTA. Header lines are ignored automatically.
Examples
Embedded from PDB FASTA records so the app remains offline after loading.
Teaching Focus
Try switching enzymes after loading chymotrypsin, or drag the hydropathy window to see local residue chemistry smooth into broader sequence regions.

Sequence length and core physical properties are calculated in the browser.
Hydropathy
Positive Kyte-Doolittle values trend hydrophobic; negative values trend hydrophilic.
Charge vs pH
The curve crosses zero near the theoretical pI, where net charge is balanced.
