Angiotensin Converting Enzyme (ACE) is the target of ACE inhibitors such as captopril that are used therapeutically to control blood pressure. The enzyme ACE converts angiotensin I to angiotensin II. Angiotensin II is an octapeptide with the sequence Asp-Arg-Val-Tyr-lle-His-Pro-Phe. What will its net charge be at pH 7? OA) -2 OB) -1 Oco OD) + OE) +2
