I have found this thread, an I heve additional question about List@@

see on example:

----------
ClearAll["`*"]; 
B[z_] := 1/(2 - z) + 3/(4 - z) + 5/(6 - z); 
B[z] (*OK*)
LB[z_] := List @@ B[z]
LB[z] (*OK*)
LB[z] /. z -> 3 (*OK*)

LB[3]  (* NOT OK*)
------------------------


 LB[3] gives   11/3 - this is a sum of term again - why ?
Is a simply way to convert B[z] ---> LB[z] 
where LB[z] is a list of simple functions of z ?
