The present invention relates to a compound comprising a peptide moiety, a linker moiety and a water-soluble polymer moiety such as a poly(ethylene glycol) moiety. The linker moiety is between the peptide moiety and the water-soluble polymer moiety. In certain embodiments, the linker moiety has the structure:
wherein α, β, and γ are each integers whose values are independently selected. In other embodiments the linker moiety has the following structure:
wherein κ, ρ, and τ are each integers whose values are independently selected. In other embodiments the linker moiety has the following structure:
wherein χ, φ, γ, and η are each integers whose values are independently selected. Alternatively, the linker structure may have the following structure:
wherein λ and μ are each integers whose values are independently selected.
