  • Predicting the Strength of Cohesive and Adhesive Interparticle Interactions for Dry Powder Inhalation Blends of Terbutaline Sulfate with alpha-Lactose Monohydrate.: Explores the critical role of alpha-lactose monohydrate, as an excipient together with terbutaline sulfate in optimizing particle interactions for enhanced performance of inhalable therapeutics (Ma CY et al., 2023).

  • Terahertz time-domain spectroscopy for the investigation of tablets prepared from roller compacted granules.: This research utilizes alpha-lactose monohydrate to examine the properties of pharmaceutical tablets, offering insights into material characteristics that affect drug delivery systems (Anuschek M et al., 2023).

生化/生理作用

α-乳糖是牛奶中主要的糖,也是新生哺乳动物通过母乳喂养获得的主要能量来源。它能被肠道乳糖酶(EC 3.2.1.108)消化,肠道乳糖酶是一种在新生儿中表达的酶。断奶后,这种酶的活性下降,导致成年哺乳动物出现乳糖不耐受。
乳糖是由一个半乳糖和一个葡萄糖分子经过缩合反应形成的二糖。乳糖是大多数物种乳汁中主要的糖,含量通常为2-8%。
