Peter,

Perhaps this is what you want:

F[a_, b_, c_, x_] := a Sin[b x + c]
parmlist = {{a1, b1, c1}, {a2, b2, c2}, {a3, b3, c3}};

(F[#1, #2, #3, x] & ) @@ parmlist[[2]]
a2 Sin[c2 + b2 x]

Or if you wish to define a new function of x for each set of parameters:

f2[x_] = (F[#1, #2, #3, x] & ) @@ parmlist[[2]]
a2 Sin[c2 + b2 x]

f2[3]
a2 Sin[3 b2 + c2]
