  • 采用硅铝酸盐沸石催化剂进行的有机溶剂中乳糖月桂酯的合成。: 该研究探讨了在硅酸铝沸石催化剂存在的情况下,利用D-乳糖一水合物和有机溶剂合成的乳糖月桂酯,突出了其在食品化学和表面活性剂中的潜在应用(Enayati et al., 2019)。

  • 在有机溶剂中使用游离和固定化脂肪酶进行的乳糖脂肪酸酯生物表面活性剂的合成和表征。: 该论文介绍了使用D-乳糖一水合物和各种脂肪酶来合成和表征乳糖脂肪酸酯,重点介绍了它们在食品和化妆品工业中作为生物表面活性剂的潜力(Enayati et al., 2018)。

生化/生理作用

乳糖是由一个半乳糖和一个葡萄糖分子的缩合形成的二糖。乳糖是大多数物种牛奶中的主要糖,通常含量在 2-8% 之间。乳糖酶将乳糖水解为其组成的单糖。在新生儿中,通过乳糖酶作用释放的葡萄糖是一种主要的能量来源。
