Maltose, a disaccharide sugar, is produced from the partial breakdown of starch and consists of two glucose units. Its unique structure is defined by the specific orientation of these glucose molecules, which impacts its chemical properties and biological function. The nature of the glycosidic linkage is what ultimately determines if the sugar is of the alpha or beta type.

Glucagon is a peptide hormone, and therefore, it is neither alpha nor beta glucose. This is a common misconception that stems from their related roles in regulating blood sugar, but the two substances are fundamentally different types of biological molecules. Understanding this key distinction is essential to grasping how the body maintains glucose balance.

While both starch and cellulose are polysaccharides made from repeating glucose units, the critical difference lies in how these units are linked. This seemingly minor distinction completely alters the molecular structure and, consequently, the biological function of each molecule.

Lactose, the primary carbohydrate found in milk, accounts for roughly 2–8% of milk's weight. This disaccharide is composed of two simpler sugar units, or monosaccharides, linked together through a glycosidic bond. It is this specific combination of monomers that answers the question: what type of glucose is lactose made up of?

Fact: Cellulose is the most abundant organic polymer on Earth, making up the cell walls of plants. So, is cellulose a monomer? The answer lies in understanding the foundational building blocks of all biological macromolecules.

The human body cannot digest cellulose, a complex carbohydrate made of beta glucose. Beta glucose, a structural isomer of alpha glucose, is the fundamental building block for a variety of critical biological molecules found extensively in nature. Understanding where it is found helps differentiate between digestible energy sources and essential dietary fiber.

According to the National Institutes of Health, glycogen is highly concentrated in the liver and muscles of animals, while starch and cellulose are polysaccharides derived from plants. While all three are made of glucose monomers, their distinct chemical structures and biological roles set them apart, influencing everything from how organisms store energy to the rigidity of plant cell walls.

Over 50% of the carbohydrates we consume come from starch. Despite being made of the same glucose building blocks, starch, glycogen, and cellulose serve vastly different purposes due to variations in their chemical structure, including how their glucose units are linked and arranged.

Over 90% of glucose in an aqueous solution exists in its cyclic, rather than linear, form. The cyclic structure of glucose gives rise to two distinct stereoisomers, known as α-D-glucose and β-D-glucose, which have an important anomeric relationship that influences their chemical and biological properties.

Cellulose is the most abundant organic polymer on Earth, making up the crucial structural component of plant cell walls. This complex carbohydrate, or polysaccharide, is exclusively composed of a single, repeating sugar molecule: beta-D-glucose.
