Transcribed Image Text:**Question #2**
Copy the structures of the following amino acids from page 40 in your text: aspartic acid, cysteine, and serine. Circle and identify (name) all of the *functional groups* present in the amino acid molecules you have drawn, even if they are not involved in *chemical bonding* between amino acids. Use an asterisk (*) to identify the functional groups that are involved in *peptide bond* formation. Finally, draw a box around the *variable group* of the amino acid.
![The image presents the structural formulas of various amino acids, highlighting specific functional groups and chain types. Below is a transcription and explanation suitable for an educational context:
### Unbranched and Branched Chain Amino Acids
1. **Serine (Ser, S)**
- Structure:
\[ \text{H}_2\text{N}-\text{CH}_2-\text{C}(OH)(=O)-\text{OH} \]
- Functional Group: Hydroxyl (—OH) group
2. **Threonine (Thr, T)**
- Structure:
\[ \text{H}_2\text{N}-\text{CH}(-\text{OH})-\text{CH}-\text{C}(OH)(=O) \]
- Functional Group: Hydroxyl (—OH) group
3. **Cysteine (Cys, C)**
- Structure:
\[ \text{H}_2\text{N}-\text{CH}(-\text{CH}_2\text{SH})-\text{C}(OH)(=O) \]
- Functional Group: Sulphur-containing —SH group
4. **Methionine (Met, M)**
- Structure:
\[ \text{H}_2\text{N}-\text{CH}_2-\text{CH}_2-\text{S}-\text{CH}_3-\text{C}(OH)(=O) \]
- Functional Group: Thioether (SC) group
5. **Glutamic Acid (Glu, E)**
- Structure:
\[ \text{H}_2\text{N}-\text{CH}_2-\text{CH}_2-\text{C}(OH)(=O) \]
- Functional Group: Additional carboxyl (—COOH) group, acidic
### Amino Acids with Additional Functional Groups
1. **Aspartic Acid (Asp, D)**
- Structure:
\[ \text{H}_2\text{N}-\text{CH}-\text{CH}_2-\text{C}(=O)(OH) \]
- Functional Group: Additional carboxyl (—COOH) group, acidic
