FAQ

Questions Protein Molecular Weight Calculator owners ask.

  • 01

    How do I calculate the mass of a protein using a composition?

    You can use the calculate_composition_mass capability by providing a JSON mapping of amino acid single-letter codes to their respective counts.

  • 02

    Can I include post-translational modifications in the calculation?

    Yes, both calculate_sequence_properties and calculate_composition_mass accept an optional modifications parameter to account for added mass.

  • 03

    What is the purpose of the extinction coefficient capability?

    The get_extinction_coefficient capability determines the UV absorption capability of a protein at 280nm based on its aromatic amino acid content.
