- 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-Ile-His-Pro-Phe. What will its net charge be at pH 7? A) -2 B) -1 O C) O D) +1 E) +2Normal arterial pH is 7.35 to 7. 45. Both metabolic and respiratory alkalosis have pH more basic compare to the normal arterial pH. The difference is 0.5 units. What is pH value in alkalosis? Niemann-Pick type C disease is a progressive neurological disease; symptoms include unsteady walking with uncoordinated limb movements, slurred speech, a difficulty in swallowing, epilepsy and tremor.

- What do you think is the ideal temperature and ph for carbonic anhydride? Why?Soy sauce is made by fermenting a salty combination of soybeans and wheat for 8 to 12 months with a variety of microorganisms, including yeast. After the particles are removed, the resultant sauce is high in lactate and ethanol. What is the process for making these two compounds?
