The Conversion of [³⁵S]PTC-Angiotensin I to PTC-Angiotensin II in Plasma of Normotensive and Hypertensive Subjects

1. The rate of conversion of angiotensin I to angiotensin II was measured by using their [³⁵S]PTC-analogues which can be separated and identified by radiochromatography.

2. There was no difference in the rate of conversion of one compound to the other in the plasma of normal subjects and hypertensive patients.
