What is the structure of lactose as shown in the diagram?
Understand the Problem
The question involves a diagram representing the structure of lactose, a disaccharide, which consists of two sugar units. It appears to illustrate the molecular composition and arrangement of atoms in lactose, including the connection between glucose and galactose monomers.
Answer
Lactose is composed of galactose and glucose linked by a beta-1,4 glycosidic bond.
The diagram shows the structure of lactose as composed of two monosaccharide units: one galactose and one glucose, linked by a beta-1,4 glycosidic bond.
Answer for screen readers
The diagram shows the structure of lactose as composed of two monosaccharide units: one galactose and one glucose, linked by a beta-1,4 glycosidic bond.
More Information
Lactose, or milk sugar, is a disaccharide made up of galactose and glucose connected by a beta-1,4 glycosidic linkage. It is important in human nutrition and lactose intolerance occurs when the body cannot efficiently break down lactose.
