Frequently Asked Questions
The Omni Peptide Calculator includes an extensive database of non-standard amino acids with their respective molecular weights and properties. Users can select from a predefined list or input custom residues with specified parameters. The system automatically adjusts calculations to account for these modifications while maintaining accuracy in the overall peptide analysis.
While the calculator provides hydrophobicity indices and other parameters related to solubility, it does not directly predict solubility in specific solvents. However, it offers valuable indicators such as grand average of hydropathicity (GRAVY) scores and charge distribution at different pH values, which researchers can use to make informed decisions about solubility and appropriate solvent systems.
The extinction coefficient calculations are based on well-established values for aromatic amino acids (tryptophan, tyrosine, and cysteine when forming disulfide bonds). The calculator uses the method of Pace et al. (1995) for most accurate predictions. For peptides with unusual modifications or chromophores, users can input custom extinction values to ensure precision in concentration determinations based on spectrophotometric measurements.
Yes, the Omni Peptide Calculator offers both monoisotopic and average mass calculations. The monoisotopic mass represents the mass of the peptide with the most abundant isotope for each element, while the average mass considers natural isotopic abundance. This feature is particularly valuable for mass spectrometry applications where isotopic distributions affect spectral interpretation.
The calculator provides options to save calculation sessions for future reference and export results in multiple formats including PDF, CSV, and text files. This functionality supports research documentation, publication preparation, and data sharing among collaborators. Saved sessions can include peptide sequences, modification specifications, and all calculated parameters.
