The Molecular weight of a 682 amino acid-long protein would be around 75kDa.
How can you determine a protein's molecular weight from an amino acid?
- When the amino acid sequence of a protein is known, we may roughly calculate the protein's molecular weight by multiplying the average molecular weight of the amino acids by the total amount of amino acids that make up the protein.
- An amino acid's molecular weight is typically 110 Daltons (Da). The total of the products of the number of picomoles of each amino acid multiplied by the associated molecular weight will give you the concentration of peptide or protein in the original sample.
- Given the number of amino acids that make up a protein, a common method to determine its molecular weight is to multiply that number by the typical weight of a 110Da amino acid.
So the MW of a 682aa-long protein would be around 75kDa.
