AFAIK there is no such function available but I may be wrong. You could write your own parser that locally redefines the macros that print stuff to macros that wraps stuff in the respective functions. In the code below, I do that for frac and sqrt. This works in this case, also because you were kind enough to explicitly spell out multiplications and even used * for them. Clearly, this "parser" is fragile, but if you really feel it is worthwhile you may add other functions like sin and so on.

Nice approach. I will experiment it a bit more, then come back in case something goes wrong.
