The octanoylated peptide hormone ghrelin regulates episodic growth hormone release and energy balance. Work in genetically modified mice (Kirchner et al., 2009) now shows that in vivo activity of ghrelin O-acyltransferase (GOAT), responsible for ghrelin octanoylation, decreases during fasting but increases after ingesting medium-chain fatty acid triglycerides (MCT).
辛酰化肽激素胃饥饿素调节生长激素的间歇性释放和能量平衡。对基因改造小鼠的研究(Kirchner等人,2009年)表明,负责胃饥饿素辛酰化的胃饥饿素O-酰基转移酶(GOAT)的体内活性在禁食期间降低,但在摄入中链脂肪酸甘油三酯(MCT)后升高。
