Abstract: Inrecentyears,greatprogress havebeenmadeonthes tudies ofmilkderivedpeptides.Thesepeptides were of great physical importance,and mo re and more attentions were attached to these peptides.Up to now,fens of t hese active peptides kinds have been found.Immunopeptide was are one of these kinds of physical peptides.They cou ld im-provetheimmunedefensivefunction ofhuman,especiallyofneonates.Thefurtherstudies andtheexploitationwouldbe of great importance.
