Actually with such species it is usually more a matter of choosing which atom types should be used for which atom, which usually determines the above parameters, which will then be looked up automatically, just as for the other .rtp entries. Parameters probably already exist in your force field for a fatty acid, and if they don't, that's probably a good reason to choose another force field.
