Chemistry
Desmopressin (1-desamino-8--arginine vasopressin) is a modified form of the normal human hormone arginine vasopressin, a peptide containing nine amino acids.
Compared to vasopressin, desmopressin's first amino acid has been deaminated, and the arginine at the eighth position is in the dextro rather than the levo form (see stereochemistry).
