Peptide coverage in major milk proteins. Peptide profiles of different infant formulae were determined and peptide coverage for peptides with ions score >20 were calculated for each amino acid of the major milk proteins αS1-casein (P02662), αS2-casein (P02663), β-casein (P02666), κ-casein (P02668), α-lactalbumin (P00711), and β-lactoglobulin (P02754) as depicted in bubble plots of the consecutive protein sequences. The size of the bubble represents the count at the corresponding position in the protein.
