Frequently Asked Questions
What is molecular weight?
Molecular weight is the sum of the atomic weights of all atoms in the peptide, including modifications and water loss in peptide bonds.
How is the isoelectric point calculated?
The isoelectric point (pI) is calculated based on the pKa values of ionizable groups and represents the pH at which the peptide has no net charge.
Why consider terminal modifications?
Terminal modifications affect peptide properties including stability, solubility, and biological activity.
