Definition of lactose
Explanation of lactose as a disaccharide sugar found in milk and dairy products
Lactose is a type of sugar that is naturally present in milk and dairy products. It is classified as a disaccharide, which means it is composed of two simpler sugar molecules, namely glucose and galactose, joined together through a chemical bond. This unique combination gives lactose its characteristic sweetness.
Lactose is the primary carbohydrate found in mammalian milk, including cow’s milk, goat’s milk, and human breast milk. It serves as an important source of energy for infants and young animals by providing readily available sugars for metabolism and growth. As mammals mature, the production of the enzyme lactase gradually decreases, making lactose digestion less efficient.
Chemical composition of lactose
The chemical structure of lactose consists of one molecule of glucose connected to one molecule of galactose through a beta-glycosidic linkage. This linkage makes lactose resistant to hydrolysis by most enzymes, except for lactase. Lactase is the enzyme responsible for breaking down lactose into its individual sugar components, which can then be easily absorbed by the body.
Lactose has a molecular formula of C12H22O11, indicating that it consists of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. It has a molecular weight of approximately 342.3 grams per mole.
In its pure form, lactose appears as a white, crystalline powder that is slightly soluble in water. It has a mildly sweet taste and is commonly used as a bulking agent or flavor enhancer in various food and pharmaceutical products.
Understanding the chemical composition of lactose is essential for individuals who are lactose intolerant or have lactose malabsorption.
