How do you explain the presence of all the six carbon atoms in glucose in a straight chain?

Explanation

To explain the presence of all six carbon atoms in glucose in a straight chain, we can follow these steps:

### Step 1: Understand the Structure of Glucose
Glucose is a six-carbon sugar (hexose) with the molecular formula C6H12O6. It has an aldehyde group (CHO) at one end and five hydroxyl groups (OH) attached to the carbon atoms. The structure can be represented as:
