3-Hydroxyoctanoic acid is the primary endogenous agonist of hydroxycarboxylic acid receptor 3 (HCA3), a G protein-coupled receptor protein which is encoded by the human gene HCAR3.[1][2] In plants, signalling chemical emitted by the orchid Cymbidium floribundum and recognized by Japanese honeybees (Apis cerana japonica).[3] " W7 A) d$ J/ o- K0 U+ {/ \ C; K 8 Q6 Y+ D1 \" S$ ~1 }机器翻译:3-羟基辛酸是羟基羧酸受体3(HCA 3)的主要内源性 激动剂,HCA 3是一种由人基因HCAR3编码的G蛋白偶联受体蛋白。[1] [2]在植物中,信号化学物质由兰花大花ym兰发出,并被日本蜜蜂(Apis cerana japonica)识别。[3]
