Angiotensin II (3-8), human

Ang IV, one of the major metabolites of angiotensin II, binds with high affinity to a new angiotensin binding site distinct and separate from angiotensin II receptors. Angiotensin II, the most potent pressor substance known, which helps regulate volume and mineral balance of body fluids.

Angiotensin II (3-8), human is a synthetic research peptide in the angiotensin peptide family. The renin-angiotensin system generates bioactive peptides by sequential proteolysis. Angiotensin I is converted by ACE to angiotensin II, while shorter metabolites such as angiotensin III and angiotensin IV have distinct receptor and enzymatic contexts. Exact residue numbering is therefore essential.

• ACE substrate and inhibition studies
• angiotensin receptor assays
• renin-angiotensin processing studies
• fragment structure-activity comparisons

The exact sequence, residue range, species, terminal state, and chemical modifications should be matched to the intended assay. Fragmentation or processing can materially alter receptor selectivity, potency, aggregation, or enzymatic behavior.
