Number (#) of potential bioactive peptides (per protein molecule) identified in the intact endogenous and dietary proteins and the A_O¹ and Y² values.

1<p>A_O is the frequency of occurrence of bioactive fragments in a protein sequence, calculated as where, a_O is the total number of identified bioactive peptides present in the protein or the number of bioactive peptides with a specific activity based on the BIOPEP database <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0098922#pone.0098922-ChairofFood1" target="_blank">[22]</a>, N is the total number of amino acid residues within the protein.</p>2<p>Y is the relative frequency of occurrence of bioactive fragments with a specific activity in a protein sequence, calculated as </p><p>where, Aoj is the number of peptides with a specific activity, l is the total number of peptide sequences across all activity categories present within the protein, j is the specified activity.</p>3<p>1 antiamnestic, 2 ACE-inhibitor, 3 antithrombotic, 4 stimulating (glucose uptake-, -vasoactive substance release), 5 regulating (ion flow-, stomach mucosal membrane activity-, phosphoinositol mechanism peptide-), 6 antioxidative, 7 bacterial permease ligand, 8 inhibitor (dipeptidyl peptidase IV inhibitor-, dipeptidyl-aminopeptidase IV inhibitor-, dipeptidyl carboxypeptidase-, CaMPDE-, neuropeptide-), 9 hypotensive, 10 activating ubiquitin mediated proteolysis.</p>4<p>Overall A_O represents the total number of amino acid sequences corresponding to known bioactive peptides identified per protein molecule across all bioactivity categories normalised for amino acid chain length.</p>5<p>The total number of bioactive peptides represents the total number of amino acid sequences corresponding to known bioactive peptides identified per protein molecule across all bioactivity categories (not just the 10 bioactivity categories shown above).
