KUGWIRITSA NTCHITO KOFUNIKA

Gastrin, yomwe imadziwikanso kuti pepsin, ndi mahomoni am'mimba omwe amatulutsidwa makamaka ndi maselo a G a gastric antrum ndi duodenum ndipo amagwira ntchito yofunika kwambiri pakulamulira ntchito ya kugaya chakudya ndikusunga kapangidwe kake ka kugaya chakudya. Gastrin imatha kulimbikitsa kutulutsa kwa asidi m'mimba, kuthandizira kukula kwa maselo am'mimba, komanso kukonza zakudya komanso kupereka magazi m'matumbo. M'thupi la munthu, gastrin yoposa 95% yogwira ntchito m'thupi ndi gastrin yokhala ndi α-amidated, yomwe makamaka imakhala ndi ma isomers awiri: G-17 ndi G-34. G-17 imawonetsa kuchuluka kwakukulu m'thupi la munthu (pafupifupi 80% ~ 90%). Kutulutsa kwa G-17 kumayendetsedwa mosamala ndi pH ya gastric antrum ndipo kumawonetsa njira yolakwika yokhudzana ndi asidi m'mimba.

Kiti iyi yapangidwa kuti iwonetse kuchuluka kwa Gastrin 17 (G-17) mu seramu/plasma/magazi athunthu a anthu. Kiti iyi imapereka zotsatira za mayeso a Gastrin 17 (G-17) zokha.
