Question

1) Please list all glycosidic linkages between each monosaccharide units. For example, α(1→4)
2) Please discuss whether these oligo/polysaccharides would be reducing or non-reducing sugar. Remember to state your reasoning in complete sentence.

### Carbohydrate Structures

The image presents two chemical structures of carbohydrates, labeled as A and B.

#### A) Structure
This structure represents a disaccharide known as sucrose, which is composed of two monosaccharides: glucose and fructose. The structure is characterized by:

- The glucose unit (left) is linked to the fructose unit (right) via a glycosidic bond.
- Hydroxyl (OH) groups are attached to several carbon atoms in both monosaccharides.
- The glycosidic bond involves the 1-carbon of glucose and the 2-carbon of fructose.

#### B) Structure
This structure illustrates a polysaccharide, specifically cellulose, with multiple glucose units. Key features include:

- The linear arrangement of β-D-glucose units indicates a long chain.
- The glycosidic linkages are β(1→4), which connect the glucose molecules, highlighted by the circled area.
- Hydroxyl (OH) groups are present on each glucose unit, contributing to hydrogen bonding.
- The repeating unit is denoted by the bracket with the variable "n" indicating the polymer chain can have multiple repeating glucose units.

These structures highlight the diversity and complexity of carbohydrate molecules, ranging from simple to complex polysaccharides, playing essential roles in energy storage and structural integrity in living organisms.
