Although you are technically folding for a single bet on the turn here, it is EXTREMELY likely that the pot will be raised at least once before it gets back to you. On the flop, 4 different players put in bets/raises, and the only likely holdings for these players which you might beat are lower aces (quite unlikely), or straight-draws. Regardless, you can't expect all of your opponents to be on these hands, and are almost certainly behind here. Therefore, I don't think you can afford to get yourself trapped into calling down with an inferior hand here.

Good fold.
