[O] latex newcommand in org

[Doyley, Marvin M.]

Hi there,

In my group, we typically response to reviewers comments (in latex) by first 
defining the  following command in the header

\newcommand{\response}[1]{\textcolor{red}{#1}}
then marking up the text as follows

\response{red text}

I try to do the same in org,  i.e., putting
 #+latex_header:\newcommand{\response}[1]{\textcolor{red}{#1}}
then \response{BLAH BLAH} in the text. The only snag is that on export I get 
\response\{BLAH BLAH\}

Any suggestion how to fix this

cheers,
M
