Lactose Formula
Lactose is a type of carbohydrate that is also called milk sugar and lactobiose. It is a disaccharide that is synthesized from galactose and glucose subunits. The “lactase” enzyme breaks lactose into glucose and galactose when it is absorbed in the intestine. It is used in the food industry, bacterial identification, and pharmaceutical industry, and is also used as a nutrient, and cutting agent. It is an essential carbohydrate for infants.
