Protein Molecular Weight Calculator
The Protein Molecular Weight Calculator is an essential tool for biochemists and molecular biologists to determine the mass of a protein based on its amino acids.
Protein MW Calculator
Calculation Formula
The molecular weight is calculated using the formula:
MW = Σ(amino acid molecular weights) - (n-1)*18.0153
Where n = number of amino acids and 18.0153 = molecular weight of water removed during peptide bond formation.
