CAS 64044-51-5

Lactose, monohydrate

Description:

Lactose monohydrate, with the CAS number 64044-51-5, is a disaccharide sugar composed of glucose and galactose, primarily found in milk. It appears as a white, crystalline powder and is hygroscopic, meaning it can absorb moisture from the environment. This compound has a molecular formula of C12H22O11·H2O, indicating the presence of one water molecule per lactose molecule. Lactose monohydrate is soluble in water, though its solubility is lower compared to other sugars, and it is less sweet than sucrose. It is commonly used in the pharmaceutical and food industries as a filler, stabilizer, or sweetener. Additionally, lactose monohydrate plays a significant role in lactose intolerance studies, as individuals lacking the enzyme lactase cannot effectively digest it, leading to gastrointestinal discomfort. Its stability and low reactivity make it suitable for various applications, including the formulation of tablets and capsules in pharmaceuticals.

D-Lactose monohydrate

CAS: 64044-51-5

Lactose is the principal sugar in human and most other mammalian milks, ( 4-O-(β-d-galactopyranosyl)-d-glucopyranose) (Collins, 2006). Lactose undergoes mutarotation; it is a reducing sugar and is significantly less soluble in water than sucrose. Lactose is much less sweet than sucrose (at ~1% about 0.15 (sucrose=1). The enzyme lactase (β-galactosidase), which is present in the small intestine, catalyzes hydrolysis of lactose to form glucose and galactose. Anhydrous lactose is an excipient, filler, diluent, and bulking agent in a wide variety of pharmaceutical tablets, capsules, powders and other preparations. Lactose also has applications as a nutrient and multi-functional ingredient in infant formulae, geriatric, dietetic and health foods (Linko, 1982).
