    Millipore β lactoglobulin a
    Hydrophobicity Index of Peptides Prior to Alkylation The detected peptides from cytochrome c, β-lactoglobulin A, and BSA are arranged in order of increasing hydrophobicity index. The hydrophobicity index is calculated for the  unmodified  form of the peptides. The marker indicates whether the peptides were found in the butanal modified or unmodified form. An x inside a circle indicates that the peptide was found in both the modified and unmodified forms. Peptides with low initial hydrophobicity indices tend to be found only in the butanal modified form while peptides that have high initial hydrophobicity indices tend to be found only in the unmodified form. The average hydrophobicity index for the peptides only found in the unmodified form is indicated by the dashed line, while the average hydrophobicity index for the peptides only detected in the modified form is indicated by the solid line.

    Article Snippet: Bovine serum albumin (BSA), horse heart cytochrome c, β-lactoglobulin A from bovine milk, the peptide Gly-Gly-Tyr-Arg (GGYR), DL-dithiothreitol (DTT), iodoacetamide (IAA), urea, trifluoroacetic acid (TFA), and ammonium bicarbonate were purchased from Sigma (St. Louis, MO).

    Percentage of Peptides Detected Across Hydrophobicity Index Range In silico  digests were performed for cytochrome c, β-lactoglobulin A, and BSA to generate a list of all peptides. Hydrophobicity indices for all peptides were calculated for both the unmodified and modified forms (using the “two-leucine” method). The percentage of peptides detected in each bin of the hydrophobicity range was calculated. Only a very small fraction of peptides having hydrophobicity indices at the extremes of the range were detected.
