Question

The total number of carbon atoms present in tyrosine, an amino acid, is _______.

Answer 1

Correct Answer: 9

To determine the total number of carbon atoms in tyrosine, we need to look at its chemical structure. Tyrosine is an amino acid with the chemical formula C₉H₁₁NO₃. This formula indicates the presence of nine carbon atoms. Let's break this down further:

1. Examine the chemical formula: C₉H₁₁NO₃.
2. The subscript next to the carbon (C) symbol is 9, indicating there are nine carbon atoms.

Therefore, the total number of carbon atoms in tyrosine is 9.

This value falls within the provided range of 9 to 9, confirming the correctness of our computation.

Answer 2

Tyrosine is an amino acid with the following structure:

The structure contains:
A benzene ring (6 carbon atoms),
A carbon atom in the side chain connected to NH$_2$ and COOH,
Two additional carbon atoms in the COOH and CH$_2$OH groups.
Total carbon atoms = 9.
