α-Lactose monohydrate

Description:
α-Lactose monohydrate, with the CAS number 5989-81-1, is a disaccharide sugar composed of glucose and galactose units linked by a β-1,4-glycosidic bond. It is a white, crystalline powder that is soluble in water, exhibiting hygroscopic properties due to the presence of a water molecule in its monohydrate form. This compound is commonly found in milk and dairy products and is often used as a sweetener, stabilizer, and bulking agent in the food and pharmaceutical industries. α-Lactose monohydrate has a relatively low sweetness compared to other sugars and is less soluble than its anomer, β-lactose. Its melting point is typically around 200°C, and it is known to undergo caramelization when heated. Additionally, it is utilized in various applications, including as a filler in tablets and as a medium for microbial growth in laboratory settings. Overall, α-lactose monohydrate is valued for its functional properties and its role in nutrition and food science.
