Question
**Peptide Analysis for Educational Purposes**

For the following peptide structure, it is required to identify:

- The number of amino acids present
- The number of chiral carbons present

When evaluating the chiral carbons, ensure to examine the side chains for chiral centers as well.

**Peptide Structure:**
The molecular structure provided is a graphical representation of a peptide chain. It includes various functional groups crucial for forming peptide bonds between amino acids. 

Key elements to look for in the diagram:
- **Amino Group (NH₃⁺):** Indicating the start of the peptide chain.
- **Carboxylate Group (COO⁻):** Typically suggesting the end of the peptide chain.
- **Chiral Centers:** Carbon atoms that have four different groups attached, creating stereoisomers.

Make sure to carefully trace the peptide bonds (C=O and NH links) and examine each constituent amino acid for chiral centers, sometimes located in the main structure or side chains.

This exercise is vital in understanding the stereochemistry of peptides, which influences protein function and folding.
