What is the number of asymmetric carbon atoms in aldopentose?

Explanation

To determine the number of asymmetric carbon atoms in aldopentose, we can follow these steps:

### Step 1: Understand the structure of aldopentose
Aldopentose is a type of sugar that contains five carbon atoms and one aldehyde group. The general structure can be represented as follows:
- The first carbon (C1) is part of the aldehyde group (CHO).
- The remaining four carbons (C2, C3, C4, C5) are part of the carbon chain.

### Step 2: Draw the structure of aldopentose
