I. Oxytocin and vasopressin are typical neural hormones , that is, hormones secreted into the circulation by nerve cells.

II. Vasopressin and oxytocin each have a characteristic neurophysin associated with them in the granules in the neurons.

III. The precursor for AVP, prepropressophysin , contains a 19-amino-acid residue leader sequence followed by AVP, neurophysin II, and a glycopeptide. 

IV. Prepro-oxyphysin, the precursor for oxytocin, is a similar but smaller molecule that lacks the glycopeptide.
