an·gi·o·ten·sin

 (ăn′jē-ō-tĕn′sĭn)
n.
Any of several polypeptide hormones, designated by Roman numerals, that are involved in the regulation of blood pressure, especially one of them, angiotensin II, which is a strong vasopressor.

angiotensin

(ˌændʒɪəˈtɛnsɪn)
n
(Biochemistry) a peptide of physiological importance that is capable of causing constriction of blood vessels, which raises blood pressure
[from angio- + tense1 + -in]

an•gi•o•ten•sin

(ˌæn dʒi oʊˈtɛn sɪn)

n.
a plasma protein that elevates blood pressure and stimulates the adrenal cortex to produce the hormone aldosterone.
[1960–65; probably angio(tonin) + (hyper)tensin, earlier names for the substance]

Results: Combination treatment with an angiotensin-converting enzyme inhibitor supplemented by an angiotensin II receptor blocking agent is expected to provide a more complete blockade of the RAAS and a better control of hypertension.
Blood pressure is controlled by hormones called angiotensins which constrict blood vessels.
By cutting off the protein's "tail", renin triggers the release of the angiotensin hormone, which then raises blood pressure.

The chapters provide insights gained by the genetic manipulation of angiotensin II, assessment of its transcriptional and translational regulation, work on the angiotensin receptors, the status of the specific molecular components of the renin-angiotensin-aldosterone system under differing conditions, and functional responses to the angiotensins.

On the other hand, a temperature optimum could be artificially created, if at a temperature >45 [degrees]C the angiotensin were broken down by increased activities of proteolytic enzymes present in the samples.
