摘要
胆囊收缩素是一种广泛分布在动物消化系统、中枢及外周神经系统的脑肠肽,对动物胃肠道的作用主要是直接抑制胃酸分泌,抑制进食后的胃排空,并通过外周和中枢神经系统抑制胃运动。同时作为一种内源性生理饱感信号,抑制摄食行为,本文就此进行了阐述。
Cholecystokinin （CCK）is a gastrointestinal and neuropeptide that is involved in many gastrointestinal functions including gallbladder contraction, pancreatic enzyme secretion, stimulation of gastrointestinal motility and inhibition of gastric emptying.Cholecystokinin is satiety signals to the central feeding system and inhibition of feeding.CCK is a heterogeneous protein that exists in a number of molecular forms derives from a propeptide precursor.Processing to the different forms is highly tissue specific and probably also species dependent.A large precursor peptides were prominent in gut extracts.
