Abstract
Polypeptides corresponding to growth hormone releasing factor in which methionine at position 27 has been replaced by a leucine residue retain full growth hormone releasing activity. In the case of the full length (44-amino acid) polypepitide, the leucine analog has full biological activity in the free acid form, unlike the natural growth releasing factor which requires carboxy terminal amidation for full biological activity.
