MeSH definition : 21-Amino-acid peptides produced by vascular endothelial cells and functioning as potent
vasoconstrictors. The endothelin family consists of three members, ENDOTHELIN-1; ENDOTHELIN-2;
and ENDOTHELIN-3. All three peptides contain 21 amino acids, but vary in amino acid
composition. The three peptides produce vasoconstrictor and pressor responses in various
parts of the body. However, the quantitative profiles of the pharmacological activities
are considerably different among the three isopeptides.;
