Find the bioactive peptides hidden in a food protein.

Start from the food, not the accession number. PepSift fetches the protein, digests it, ranks every peptide released against the published patterns for blood-pressure, blood-glucose, antioxidant and antimicrobial activity, and tells you which enzyme to use to get the most of them with the least bitterness.

DH is the share of peptide bonds cut — the dial you set in the lab. Leave it on complete digestion to see everything an enzyme could ever release.
