More than a dozen peptides and proteins have been isolated from the Gila monster's venom,

hyaluronidase, serotonin, phospholipase A2, and several kallikrein-like glycoproteins

Peptide : EXENDIN-4

The venom

50% similar to the human hormone glucagon-like peptide-1 (GLP-1) that increases the production of insulin when blood sugar levels

are high.

EXENDIN-4

May help to treat type-2 diabete

EXENATIDE

• remains effective much longer than the human hormone

its synthetic form helps diabetics keep their blood sugar levels from getting too high

• slows the emptying of the stomach and causes a decrease in appetite,

leads to weight loss

EXENDIN-4

It can kill

But it can heal.
