GA22011

H-Ala-Leu-Pro-Met-His-Ile-Arg-OH

Also known as (2S)-2-[[(2S,3S)-2-[[(2S)-2-[[(2S)-2-[[(2S)-1-[(2S)-2-[[(2S)-2-aminopropanoyl]amino]-4-methylpentanoyl]pyrrolidine-2-carbonyl]amino]-4-methylsulfanylbutanoyl]amino]-3-(1H-imidazol-5-yl)propanoyl]amino]-3-methylpentanoyl]amino]-5-(diaminomethylideneamino)pentanoic acid

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
