Frequently Asked Questions
Q: What is a peptide calculator used for?
A peptide calculator is used to determine various physicochemical properties of a peptide sequence, such as its molecular weight, isoelectric point (pI), extinction coefficient, charge at a given pH, and amino acid composition.
How do you calculate the molecular weight of a peptide?
The molecular weight of a peptide is calculated by summing the molecular weights of all its constituent amino acid residues and then subtracting the molecular weight of water for each peptide bond formed (i.e., number of amino acids – 1).
What is an isoelectric point (pI) for a peptide?
The isoelectric point (pI) of a peptide is the pH at which the peptide carries no net electrical charge. At this pH, the sum of all positive and negative charges on the amino acid residues and termini is zero.
Why is knowing a peptide's properties important?
Knowing a peptide’s properties is crucial for various biochemical and biotechnological applications, including designing experiments, predicting solubility, optimizing purification protocols (e.g., chromatography), and understanding its biological function.
