Ammonia, NH3, and ammonium ion, NH4+, are both soluble in water and could be easily excreted in the urine. Why does the body convert them to urea rather than excreting them directly?
Consider the decapeptide angiotensin I.a. What products are formed when angiotensin I is treated with trypsin?b. What products are formed when angiotensin I is treated with chymotrypsin?c. Treatment of angiotensin I with ACE (the angiotensin-converting enzyme) cleaves only the amide bond with the carbonyl group derived from phenylalanine to afford two products. The larger polypeptide is angiotensin II, a hormone that narrows blood vessels and increases blood pressure. Give the amino acid sequence of angiotensin II using three-letter abbreviations. ACE inhibitors are drugs that lower blood pressure by inhibiting the ACE enzyme
