The image displays structural formulas of four different amino acids labeled a, b, c, and d.

**a.) Phenylalanine**
- **Structure:** Contains a benzene ring attached to a CH2 group which is connected to an amino group (NH2) and a carboxyl group (COOH).

**b.) Tyrosine**
- **Structure:** Similar to phenylalanine but with an additional hydroxyl group (OH) attached to the benzene ring. It includes a CH2 group linked to an amino group (NH2) and a carboxyl group (COOH).

**c.) Valine**
- **Structure:** Consists of a branched alkyl chain. The central carbon is attached to two CH3 groups, one H, an amino group (NH2), and a carboxyl group (COOH).

**d.) Glutamic Acid**
- **Structure:** Includes a longer chain with a carboxyl group attached to the carbon chain, along with an amino group (NH2) and another carboxyl group (COOH). This results in two carboxylic acid groups.

These structural formulas highlight the basic architecture and side chain variations of each amino acid, affecting their function in proteins.
