Replace description of abbreviation in list of acronyms

For my current protocol I use the Glossaries package and everthing works fine. But I want some things to modify and for this I need some hints.
I use an abbreviation that is in english. So in the list of acronyms I would like to give more details as only the long form of the acronym.

Example:

• acronym: AC

• description: alternating current [engl.: „Wechselstrom“; meint auch Gleichspannung]
  In the text obviously I just want to display Wechselstrom as long form.

So what do I to adjust? Thanks!

little example:

documentclass[11pt,a4paper]{article}
usepackage[utf8]{inputenc}
usepackage[german]{babel}
usepackage[T1]{fontenc}

usepackage[acronyms,nomain]{glossaries}
makeglossaries

newacronym{ac}{AC}{Wechselstrom}

begin{document}
printacronyms

Some text about gls{ac}. Some further text about gls{ac} to show the abbreviation displayed.
end{document}

[description={ alternating current [engl.: glqq Wechselstromgrqq; meint auch Gleichspannung]}]
