**Title: Understanding Glycosidic Bonds in Disaccharides**

**1. Name the Glycosidic Bonds:**

- **1:** ________
- **2:** ________

**2. Diagrams and Analysis:**

The image contains two chemical structures of disaccharides connected through glycosidic bonds. Each structure consists of two monosaccharide units linked by an oxygen bridge. Here is a detailed explanation of the diagrams:

- **Diagram on the Left:**
  - Two six-membered rings represent hexose sugars (e.g., glucose or galactose).
  - The glycosidic bond connects the anomeric carbon of one sugar to the hydroxyl group of the other.
  - Common disaccharide examples for such structures include lactose, maltose, etc.

- **Diagram on the Right:**
  - This is similar in structure to common disaccharides such as sucrose, where the glycosidic bond may involve a five-membered ring (e.g., fructose) with a six-membered ring.

**3. Questions and Answers:**

- **3. What two monosaccharides make up lactose?**  
  _________ & _________

- **4. What two monosaccharides make up sucrose?**  
  _________ & _________

- **5. What two monosaccharides make up maltose?**  
  _________ & _________  

These exercises help reinforce the understanding of how different monosaccharides combine to form various disaccharides and the role of glycosidic bonds in these structures.
