Are aspartic acid and glutamic acid at physiological pH present in zwitterionic form?

I am wondering whether aspartic acid and glutamic acid at physiological pH are present in zwitterionic form? In my textbook it says that all aminoacids at $\textrm{p}H$ of 7.4 or 7 are in zwitterion form. I wonder if $\textrm{p}K\_\textrm{a}$ values of side chains of aspartic acid is 3.65. There are also arginine, lysine, cysteine and tyrosine that will not have overall neutral charge at $\textrm{p}H = 7$.




The [IUPAC goldbook defines a zwitterion](https://goldbook.iupac.org/html/Z/Z06752.html) as being overall neutral. Any other definition is thus contrary to the standard definition.
