一般描述
胰α淀粉酶由胰腺泡细胞产生并释放至十二指肠。它是胰液的主要分子。
应用
α-猪胰腺淀粉酶用于：
- 体外消化系统，研究豌豆球蛋白的水解
- 体外α淀粉酶抑制研究
- 制备人体消化系统的体外模型消化液（唾液）
生化/生理作用
α-淀粉酶是一种淀粉水解酶，用于生产对能量摄取至关重要的葡萄糖。它可催化水解淀粉中的α-1,4-糖苷键，形成葡萄糖、麦芽糖和麦芽三糖单元。在哺乳动物中，α-淀粉酶通过减少Na+/葡萄糖转运载体1(SGLT1)并刺激糖蛋白N-聚糖介导淀粉消化，调节糖同化。α-淀粉酶抑制剂与II型糖尿病的治疗有关。α-淀粉酶是一种广为人知的工业酶，适用于食品、洗涤、纺织、发酵和制药行业。
单位定义
1单位酶相当于在pH 6.9和25℃条件下，每分钟释放1 μmol麦芽糖所需的酶量（淀粉符合Zulkowsky，货号85642，作为底物）
其他说明
最佳酸碱度和温度分别为6.9和53℃；钙是活性所必需的，也能防止胰蛋白酶降解；表征。
