The total number of carbon atoms present in tyrosine, an amino acid, is _______.
Correct Answer: 9
Approach Solution - 1
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:
- Examine the chemical formula: C9H11NO3.
- 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.
Approach Solution -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.
