shorthand

I'd like to define a shorthand command for \begin{align*} and \end{align*}. When I write
\newcommand{\ba}{\begin{align*}}
it works fine. But when I write
\newcommand{\ea}{\end{align*}}
latex complains. It looks like it's interpreting it as part of the environment and is not happy with that. Anyone know how to fix this?
