the hypothesis that the cooh-terminal heptapeptide mediates the aldosterone-stimulating activity of angiotensin ii was evaluated by comparing the relative effects on aldosterone production of angiotensin ii and the heptapeptide to angiotensin analogues that are poorly metabolized to the heptapeptide and to a nonapeptide , des-asp-1-angiotensin i , that is directly converted to the heptapeptide .
