Purification and characterisation of angiotensin I converting enzyme (ACE) inhibitory peptides derived from enzymatic hydrolysate of ovotransferrin

► Conditions for preparation of peptides are based on QSAR and bioinformatics. ► The identity of the peptides is known during purification. ► There is no difference between synthetic peptides and purified peptides. ► IQW and LKP, but not IRW, are resistant to gastrointestinal enzymatic degradation.
