Adipokinetic hormone (AKH) is a short peptide hormone found in insects. AKH is responsible for regulating fuel transport in the haemolymph. It is released from cells in the corpora cardacia after the beginning of flight causing the diglycerides from the fat body to be used as energy source.Locust: pGlu-Leu-Thr-Phe-Thr-Ser-Trp-Gly-NH2 or pELTFTSWG-NH2
