String manipulation (adding additional characters and spaces)

tostr = [3 14; 4 38; 5 25; 15 1; 16 196];
str=num2str(tostr);

How can I modify the above created string 'str' into the following (example for row 1):

'F 3 (n 14) ' (with a space after the last bracket)

and then concatenate the different rows into one single string:

'F 3 (n 14) F 4 (n 38) F 5 (n 25) F 15 (n 1) F 16 (n 196)'
