Amino acid R groups (side chains) may be hydrophobic, hydrophilic, acidic, or basic. The diagram presents four different amino acid R groups. Ala: $\text{CH}_3$ Asp: $\text{COOH}$ attached to $\text{CH}_2$ Lys: $\text{NH}_2$ attached to $(\text{CH}_2)_4$ Ser: $\text{OH}$ attached to $\text{CH}_2$ Which row is correct for these amino acid R groups?
- Ahydrophobic: Ala; hydrophilic: Ser; acidic: Asp; basic: Lys
- Bhydrophobic: Ala; hydrophilic: Ser; acidic: Lys; basic: Asp
- Chydrophobic: Asp; hydrophilic: Lys; acidic: Ser; basic: Ala
- Dhydrophobic: Asp; hydrophilic: Ser; acidic: Lys; basic: Ala
