Structure Of Lactose

Lactose is a disaccharide sugar that is formed by the β-1→4 glycosidic linkage of β-D-glucose and β-D-galactose.

 

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.

What is Lactose Formula?

The molecular formula of lactose is C12H22O11, i.e., it is composed of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. It is a white solid that has a mild sweet taste. It is soluble in water and is a non-hygroscopic solid. Lactose was first discovered by Italian physician Fabrizio Bartoletti. Milk contains around 2-8% lactose (by mass). Lactose is found in the mammary glands of all mammals, and a very small amount of lactose can be found in dairy products like yogurt and cheese. It is less sweet when compared to sucrose....
