Simulation results for the retractive forces of a [VPGVG]₅ and AAAAA peptide

	End-to-end displacement Δr (Å)	Entropic force (kJ/mol)	Energy force (kJ/mol)	Total force (kJ/(mol Ǻ))
[VPGVG]5
Water	89.4	8.1	−0.2	8.0
2 M glucose	72.7	6.3	3.7	10.0
AAAAA
Water	5.5	22.7	6.7	29.3
2 M glucose	8.5	14.1	3.5	17.7

Entropic force and energy forces are computed from the values in Table 5. Entropic force is given by $f_s=-T\Delta s/\left(\Delta r\right)$ (T = 310 K) and energy force by $f_{\mathrm{e}}=\Delta U/\Delta r$.
