消化食物脂肪的消化酶主要来自胰腺。在人类发现,非胰腺来源,即来自十二指肠以上部位的脂酶,可消化胃内脂肪,在小肠的作用次于胰腺。胰腺外分泌功能不全时,非胰性脂肪消化酶更显重要。作者曾报道胰腺囊性纤维变性(CF)患者Treitz韧带处非胰性脂肪消化酶占总消化酶的90%,主要有舌脂酶和胃脂酶,其特性与胰脂酶不同,最适pH较低,不依赖胆盐和辅脂酶。慢性酗酒引起的胰功能不全(API)患者餐后十二指肠 The digestive enzymes that digest food fat come mainly from the pancreas. In humans, non-pancreatic sources, lipases from above the duodenum, digest stomach fat and in the small intestine secondary to the pancreas. Pancreatic exocrine insufficiency, non-pancreatic fat digestive enzymes more important. The authors report that non-pancreatic fat digestive enzymes account for 90% of the total digestive enzymes in the Treitz ligament of patients with pancreatic cystic fibrosis (CF), mainly lipolytic enzymes and gastric lipases, which differ from pancreatic lipase in their optimal pH Lower, independent of bile salt and co-lipase.
