Lactose

Lactose is a disaccharide sugar found in milk and dairy products. It is composed of galactose and glucose and is a primary source of carbohydrate in the diets of many mammals during infancy. The human body needs the enzyme lactase to digest lactose; individuals who lack sufficient lactase often experience lactose intolerance. This condition can cause digestive discomfort like bloating, diarrhea, and gas after consuming dairy products. lactose is also used as an excipient in some medications and supplements. The breakdown of lactose produces energy and contributes to the unique flavor and texture of dairy products. The ability to digest lactose, known as lactase persistence, varies significantly among different populations.
