Other Notes
1 U相当于在pH 7.0和37°C下每分钟释放1μmol胆固醇的酶的量(乙酸胆固醇为底物)。
Application
猪胰脏的胆固醇脂酶用于:
- 体外模拟消化模型,改善类萝卜素酯在肠期的水解作用
- 分析体外模拟消化模型中析植物固醇和胆固醇在水胶束相中的生物有效性
- 作为酶活性测定的标准品
Biochem/physiol Actions
胆固醇酯酶(CEase)是具有广泛底物特异性的酶,在调节胆汁盐介导的膳食胆固醇酯水解过程中起着关键作用。它还参与甘油三酯和磷脂的水解,这也是正常胆固醇吸收所必需的。胆固醇酯酶水解有助于确定血清和血浆中的总胆固醇水平。此外,胆固醇酯酶(CEase)与磷脂酶A2一起参与卵磷脂水解为溶血卵磷脂,形成肠道胶束,将游离胆固醇输送到肠上皮细胞。酶功能丧失会导致膳食胆固醇酯的肠道吸收减少,并阻止肠道胶束的形成,从而无法有效地输送胆固醇。动脉粥样硬化病变中积聚的循环胆固醇酯酶参与触发平滑肌细胞的增殖。最后,它们还选择性地参与羧酸酯键的水解/缩合。

General description
研究领域:细胞信号传导
胰胆固醇酯酶(CEase),也称为胆汁盐刺激脂酶,是属于α/β水解酶家族的丝氨酸水解酶。它们由外分泌胰腺释放。丝氨酸194、组氨酸435和天冬氨酸320代表该酶的催化三联体。
