The analysis of a peptic bovine hemoglobin hydrolysate, produced at pi
lot plant scale, was carried out using two techniques: SE-HPLC and RP-
HPLC. Analysis of amino acid composition, second-order derivative spec
trometry and FAB mass spectrometry of isolated peptides allowed us to
determine the exact positions of these peptides in the sequence of bov
ine hemoglobin. This, consequently, gave rise to a peptidic map of the
hydrolysate. It also revealed, at the same time, some biologically ac
tive peptides in the hydrolysate. This information should find use in
the potential future application of enzymatic bovine hemoglobin hydrol
ysate.
