补充资料:C24类甾醇类
分子式:
CAS号:

性质:胆汁酸属于类甾(或固)醇类,又称为C24类甾醇类。正常人胆汁中有结合胆汁酸和游离胆汁酸两大类,并以前者为主。游离胆汁酸有胆酸、脱氧胆酸和鹅脱氧胆酸等;结合胆汁酸系指上述胆汁酸以酰胺键(简称肽键)与甘氨酸或牛磺酸结合,分别成为甘氨胆酸或牛磺胆酸等。这些化合物存在于大多数脊椎动物中,是“胆苦”的主要成分。结合胆汁酸易溶于水,这是由于其分子中既含有亲水的羟基和羧基,又含有疏水的甲基,且这两种性质不同的基团又完全排列在环戊烷多氢菲核的两侧,使分子分为“亲水”和“疏水”两个侧面。故结合胆汁酸具有强乳化剂功能,使肠腔内油脂乳化成微粒,以增加油脂与消化液中脂肪酶(lipase)接触面积而便于脂类消化吸收,同时也促进对脂溶性维生素的吸收。
