Peptide Calculator: Accurate Dosage & Molecular Weight Tools

Our peptide calculator will help you accurately determine the molecular weight of your peptide sequence.

Peptide Calculator

Use this peptide calculator to easily calculate the molecular weight of your peptide. Simply enter your peptide sequence into the input field and press “Calculate”. The molecular weight will be displayed in Dalton (Da).

How To Use It

  1. Enter your peptide sequence into the field without any spaces or special characters.
  2. Press the “Calculate” button to get the result.
  3. The molecular weight of your peptide will be displayed in the “Result” field.

How It Calculates the Results

The calculator computes the molecular weight by summing the standard molecular weights of each amino acid in the sequence. The values are based on the molecular weights of the 20 standard amino acids.

Limitations

This calculator assumes standard peptide bonds and does not account for post-translational modifications, non-standard amino acids, or unusual linkages which could affect the actual molecular weight. Special characters and spaces should not be included, and only standard amino acids represented by their one-letter codes should be used. It is important to verify the calculated molecular weight with actual experimental data.
