α-L-岩藻糖甙酶,全称α-L-岩藻糖甙岩藻糖水解酶(EC3.1.1.51,α-L-fucosidase;α-L-fucosidefucohydrolase,简称AFU),是一种广泛存在于人和动物体内的酸性水解酶,在糖蛋白和糖脂的代谢中有重要作用。现已发现某些疾病(如岩藻糖甙沉积病和卵巢癌等)患者的血清和组织中AFU活性水平明显低于正常;而另一些疾病[如原发性肝癌(Primary Hepatic Carcinoma,简称PHC)、胃癌、结肠癌、急性病毒性肝炎等]患者血清中该酶 α-L-fucosidase, full name α-L-fucosyloside fucose hydrolase (EC3.1.1.51, α-L-fucosidase; α-L-fucoside fucohydrolase, abbreviated as AFU), is a kind of Acid hydrolase, which is widely present in humans and animals, plays an important role in the metabolism of glycoproteins and glycolipids. It has been found that the levels of AFU activity in serum and tissues of patients with certain diseases (such as fucoidose deposition disease and ovarian cancer) are significantly lower than normal; while other diseases [such as primary hepatic carcinoma (PHC) ), Gastric cancer, Colon cancer, Acute viral hepatitis, etc.] Serum in the patient
