Quantitative structure-activity relationship modelling of ACE-inhibitory peptides derived from milk proteins

Quantitative structure-activity relationship modelling of ACE-inhibitory peptides derived from milk proteins

Quantitative structure-activity relationship (QSAR) modelling was performed on peptides derived from milk proteins that inhibit angiotensin-I-converting enzyme (ACE). Physico-chemical descriptors expressed hydrophobicity, size and charge of side chains of the two most external amino acids in N- or C...

Zusammenfassung:Quantitative structure-activity relationship (QSAR) modelling was performed on peptides derived from milk proteins that inhibit angiotensin-I-converting enzyme (ACE). Physico-chemical descriptors expressed hydrophobicity, size and charge of side chains of the two most external amino acids in N- or C-terminal position. Models were estimated with partial least squares regression and validated with full cross-validation. A relationship (R=0.73, p
