Question
**Identify the Anomeric Carbon and Glycosidic Linkage of Lactose**

This image illustrates the molecular structure of lactose. Lactose is a disaccharide composed of two sugar units. 

### Description of the Diagram:

- **Anomeric Carbon:**
  - The anomeric carbon is the carbon linked to the oxygen in the glycosidic bond. In lactose, this is typically the carbon 1' of the galactose unit on the left.
  
- **Glycosidic Linkage:**
  - The glycosidic linkage in lactose is a β(1→4) linkage. This connects the anomeric carbon of the galactose (left) to the fourth carbon of the glucose (right) unit.

### Structural Details:

- **Galactose Unit (Left):**
  - Displays various hydroxyl (OH) groups, with the anomeric carbon connected by a glycosidic bond.
  
- **Glucose Unit (Right):**
  - Also features multiple hydroxyl groups, forming the other part of the glycosidic linkage.

Understanding the structure of lactose helps in studying its digestion and function in biological systems.
