β-Lactoglobulin (142-148)

The lactokinin ALPMHIR is an angiotensin-converting enzyme (ACE) inhibitory peptide, which corresponds to a sequence released by tryptic digestion from the milk protein β-lactoglobulin. It might be useful in the treatment of hypertension although its ACE inhibitory activity is about a 100 times lower than that of the antihypertensive drug captopril.
