Introduction of "Peptide":
Peptide is a connect with peptides and amino acids, but each of these peptides can consist of a variety of amino acids. Two kinds of amino acid composition of call two peptides, three kinds of amino acids is composed of three peptides, and so on. Now hear the three peptides, five peptides, even nine peptide, belong to the peptide chain. Each of the peptide chain has a different effect. Usually less than 10 amino acid peptide called oligopeptide, called polypeptide amino acids for more, more than 50 called protein. Because of containing amino acid of different varieties and two peptides, three peptides have different varieties, thus arises now has all kinds of action, all kinds of names "peptide".

Applications:

Mainly has a strong angiotensin II vasoconstriction and increase in blood pressure. The mechanism is: 1. So that the body arteriole smooth muscle contraction, increased peripheral resistance; 2. So increase the release of adrenal aldosterone, causing sodium retention, increased blood volume; 3. Directly contribute to renal tubular sodium and water reabsorption; 4. So the brain central nervous sympathetic vasoconstrictor activity, causing increased peripheral vascular resistance; 5. Stimulate the adrenal medulla to release epinephrine and norepinephrine
