For the designation of atoms, IUPAC recommends the substitution of Greek letters by the equivalent uppercase Roman letters.

*A scale combining hydrophobicity and hydrophilicity of R groups; negative numbers tend to be hydrophilic, positive numbers tend to be hydrophobic.
**Hydrophobic = L, Hydrophilic = W, Neutral = N
