Pyranose ring consist of a skelton of:

Options

A. 5 carbon atoms and one oxygen atom
B. 6 carbon atoms
C. 6 carbon atoms and one oxygen atom
D. 4 carbon atoms and one oxygen atom

Explanation

To solve the question regarding the skeleton of a pyranose ring, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Pyranose**:
- The pyranose ring is a six-membered cyclic structure. It is derived from pyran, which is a six-membered ring containing one oxygen atom.

2. **Identify the Atoms in the Ring**:
- In the pyranose ring, there are a total of six atoms: five carbon atoms and one oxygen atom.

3. **Count the Carbon Atoms**:
- The structure of the pyranose ring consists of five carbon atoms. These carbons are part of the ring structure.

4. **Count the Oxygen Atom**:
- There is one oxygen atom in the pyranose ring, which is essential for its cyclic structure.

5. **Summarize the Skeleton Composition**:
- Therefore, the skeleton of the pyranose ring consists of five carbon atoms and one oxygen atom.

### Final Answer:
The pyranose ring consists of a skeleton of **five carbon atoms and one oxygen atom**.
