Bash, [.bashrc] a function for an alias

Question

[In my .bashrc]

Basically I try to make an alias:

alias e='su -c'

But when I write in a terminal:

~$ e ls -goFha /root 

I (obviously) get the error:

su: group oFha does not exist

---

If $str were replaced by the rest of the command, the herebelow code would work:

alias e='su -c "$str"'

But alias don't work this way. Therefore, I thought to a function.

Replacing $str by the whole argument string, it could be something like:

e () {
  "su -c '$str'"
}

How to get the whole argument string in a function?

How would you write my function?

Thanks

Here is another solution:

e() { 
   su -c "$*"
}

You can try this:

    e () {
      CMD="$@"
      su -c "$CMD"
    }
