Experimental results describing a protein's amino acid composition are useful for estimating the molecular weight (MW) of the entire protein. A quantitative amino acid analysis reveals that bovine cytochrome c contains 2% methionine (M. 149) by weight. Calculate the approximate molecular weight of bovine cytochrome c if there are 2 methionine residues. 1 approximate bovine cytochrome c MW: 14900 Da Incorrect Bovine chymotrypsinogen has a molecular weight of 25.6 kDa. Amino acid analysis shows that this enzyme is 11% serine (M, 105). Calculate how many serine residues are present in a molecule of bovine chymotrypsinogen. Round your answer to the nearest whole number 31 number of serine residues: Incorrect
