Understanding Protein Molecular Weight

Protein molecular weight is the sum of the atomic weights of all atoms in a protein molecule. It's calculated by adding up the molecular weights of individual amino acids in the protein sequence, including any post-translational modifications.

Applications in Research

Protein molecular weight is crucial for protein purification, gel electrophoresis, mass spectrometry analysis, and understanding protein structure and function. It helps in determining protein concentration and in various biochemical applications.

Calculation Method

The molecular weight is calculated by summing the weights of all amino acids in the sequence, subtracting the weight of water molecules lost during peptide bond formation, and adding any post-translational modifications if present.
