Protein/peptide/amino acid bioinformatics Tools:
Protein GRAVY returns the GRAVY (grand average of hydropathy) value for the protein sequences you enter.

Protein GRAVY returns the GRAVY (grand average of hydropathy) value for the protein sequences you enter. The GRAVY value is calculated by adding the hydropathy value for each residue and dividing by the length of the sequence (Kyte and Doolittle; 1982).
