Which disaccharide aids in the absorption of calcium and supports the growth of beneficial bacteria in the large intestine?

Lactose is the disaccharide that aids in the absorption of calcium and supports the growth of beneficial bacteria in the large intestine. This sugar, which is found in milk and dairy products, is broken down into glucose and galactose by the enzyme lactase. Calcium absorption is enhanced because lactose can help increase the solubility of calcium in the intestine, thereby facilitating its absorption into the bloodstream.

Moreover, lactose acts as a prebiotic, meaning it serves as a food source for probiotics, the beneficial bacteria residing in the gut. These bacteria play a crucial role in maintaining intestinal health, enhancing the immune response, and improving the overall balance of the gut microbiota.

In contrast, other disaccharides such as sucrose, fructose, and maltose do not have the same beneficial effects on calcium absorption or the support of beneficial gut bacteria. Sucrose, while an energy source, does not promote probiotics nor assist with calcium absorption as effectively. Maltose, composed of two glucose units, lacks specific properties associated with calcium absorption and prebiotic function, and fructose is a monosaccharide that does not serve as a significant source for probiotic bacteria in the same way that lactose does. Thus, lactose stands out for its unique roles
