List I | Functional Group | List II Description |
---|---|---|
A | Hydroxyl | I. DNA |
B | Carboxyl | II. Proteins |
C | Amino | III. Polar |
D | Phosphate | IV. Fatty acids |
- Hydroxyl (A - III): Hydroxyl groups are highly polar due to the electronegativity of oxygen.
- Carboxyl (B - IV): Carboxyl groups are a major component of fatty acids.
- Amino (C - II): Amino groups are found in amino acids, which are the building blocks of proteins.
- Phosphate (D - I): Phosphate groups form the backbone of DNA molecules.
