There is no need to run multiple Chrome profiles if you want to use one and the same Google account.
Probably what you want is to run multiple separate instances of Chrome, since this would allow you to use one and the same Google account, therefore sync all the bookmarks, extensions, settings etc., but have different logins, for instance, on Facebook or any other non Google websites and services.
