The only different are the quotes. You could try adding back the quotes, however at this point I recommend you not messing with it any further. You need to revert the change now.

1) Install leafpad
2) run the following in xterminal

Code:

sudo leafpad /etc/profile

3) remove the last two lines containing http_proxy
4) click on the top bar to drop down a menu where you could find 'Save'. Save the file
5) Exit the program
