Angiotensinconvertingenzyme2regulatesheartfunction

Cardiovascular diseases are predicted to be the most common cause of death worldwide by 2020. The major regulator of blood pressure homeostasis is the renin-angiotensis system. Angiotensinogen is digested by renin to produce angiotensin I (AGT I). AGT I is an inactive 10 amino-acid peptide that is further degraded to produce angiotensin II by the agiotensin-converting enzyme (ACE). Angiotensis II is the master regula......阅读全文
