[The surface-active properties of angiotensin].
The surface activity of angiotensin-2 was studied using the method of dynamical capacitor and Wilgelmi. Angiotensin was shown to possess the surface activity, forming well regulated insoluble monolayers of liquid-gas interfaces with peptide adsorption of 3.7 x 10(-6) M/sm2 and area of 0.45 nm2 per one molecule. It is assumed that due to these properties angiotensin-2 under physiological conditions can interact with molecules of the lipid matrix of biological membranes.
