Scientific Basis of the Calculator
The Protein Molecular Weight Calculator is based on the principle that a protein’s molecular weight is the sum of the average molecular weights of its amino acids, adjusted for water loss during peptide bond formation. The calculator uses the following formula:
Molecular Weight (Da) = Σ(Amino Acid Weights) - (n-1) × 18.015
Where:
- Amino Acid Weights: Average molecular weights of each amino acid (e.g., A = 71.08 Da, C = 103.14 Da).
- n: Number of amino acids in the sequence.
- 18.015: Molecular weight of water lost per peptide bond.
Average amino acid weights are sourced from peer-reviewed biochemical data, ensuring accuracy. This methodology is widely used in proteomics and validated by studies like those referenced in Protein Molecular Weight.
