PYY 3-36

In biology, the hormonecalled PYY 3-36 plays a critical role in decreasing appetites, making us aware of fullness of our stomach. The injection of PYY in rats in an experiment revealed that they eat much less by 30% than usual, resulting in weight loss. This also applies to the human body. Therefore, researchers have thought that this could be used a very effective treatment for obesity, though it has not yet perfectly admitted as a practical drug. PYY 3-36 has been lauded as likely to be saferthan other drugs used to treat obesity.

The hormone that has the opposite role is known as ghrelin- instead of inhibiting the desire for food, it increases appetite.

Nastech Pharmaceuticalshas a version of this hormone in human trials. If all goes well, it should be approved by the FDA by 2007.nl:PYY 3-36
