About the Peptide Calculator
This peptide calculator tool helps researchers and scientists quickly determine important properties of peptide sequences. Simply enter your peptide sequence in one-letter code (e.g., ACDEFGHIKLMNPQRSTVWY) and our tool will calculate:
- Molecular weight (monoisotopic and average)
- Amino acid composition and count
- Theoretical isoelectric point (pI)
- Extinction coefficient
- Net charge at pH 7.0
- Peptide concentration (if mass and volume are provided)
The calculator supports common peptide modifications like acetylation, amidation, phosphorylation, and more. Results are displayed instantly with clear, easy-to-understand formatting.
