“…Angiotensin II is a vasoconstrictor, which inhibits bradykinin, a vasodilator ( Fig. The dodecapeptide, α s1 -CN f23-34, from tryptic hydrolysates of casein, inhibits ACE; the C-terminal sequence, α s1 -CN fl94-199, also has ACE inhibitory activity and both probably increase bradykinin (morphine) and may induce apnea and irregular breathing, stimulate food intake and increase insulin output among many other properties (see Xu 1998). ACE inhibitors derived from casein, called casokinins, have been identified within the sequences of human β-CN (Kohmura et al 1989;Bouzerzour et al 2012) and k-CN (Kohmura et al 1990) and bovine α s1 -and β-CNs (Maruyama and Suzuki 1982;Meisel and Schlimme 1994).…”
