renin

noun ˈriːnɪnˈrinɪn
mass nounBiochemistry
  • An enzyme secreted by and stored in the kidneys which promotes the production of the protein angiotensin.

    〔生化〕肾素,高血压蛋白原酶,血管紧张肽原酶

    Example sentencesExamples
    • By causing volume and sodium depletion, thiazide diuretics stimulate the production of renin and angiotensin.
    • Angiotensinogen, the initial substrate of the renin-angiotensin-aldosterone system, is produced in the liver; renin converts it to angiotensin I in the kidneys.
    • By regulating salt levels through production of an enzyme called renin (as well as other substances), the kidneys ensure that blood pressure is regulated.
    • All these changes act directly or indirectly as stimuli for the release of the enzyme renin in the kidneys, triggering a sequence of chemical events in the blood of which the end product is angiotensin II.
    • The greatest cause is probably due to lower production of hormones such as renin, angiotensin and aldosterone, caused by the increased stress (these hormones assist the body in retaining fluid).
