Comments = Heptanoic Acid = 5,5,5-trifluoroleucine = 5,5,5,5',5',5'-hexafluoroleucine = N-terminal Ornithine = Ornithine

No frcmod file supplied because no new parameters (besides the charges) required. Capping groups of ACE and NME were used to create the dipeptide consistent with the Cornel et al forcefields. Charges were determined using a 2 stage method, I used Gaussian 98 (HF 6-31g*) to minimize the structure using tight convergence and an SCF criterion of 10^-8 au. Gamess (HF 6-31g*) was used to calculate the MEP using six different orientations. RESP converted the MEP to resp charges averaged along the different orientations and accurate to six digits beyond the decimal point.

Regarding Heptanoic Acid: Full complete name is (S)-2,7-Diaminoheptanoic acid
