α-D-Lactose

Description:
α-D-Lactose, with the CAS number 14641-93-1, is a disaccharide sugar composed of one molecule of glucose and one molecule of galactose linked by a β-1,4-glycosidic bond. It is an isomer of β-D-lactose and is commonly found in milk and dairy products. This compound is a white, crystalline solid that is soluble in water, exhibiting a sweet taste. α-D-Lactose plays a significant role in the food industry, particularly in infant formula and dairy products, due to its nutritional value and ability to enhance flavor. It is also utilized in pharmaceutical formulations as a filler or excipient. The melting point of α-D-lactose is typically around 200°C, and it is hygroscopic, meaning it can absorb moisture from the environment. In terms of its chemical properties, α-D-lactose can undergo hydrolysis in the presence of acids or enzymes, breaking down into its constituent monosaccharides. Its stability and reactivity make it an important compound in both food science and biochemistry.
