[texhax] organic chemisty with LaTeX

[Renju Zacharia]

Dear TeX users,

How do I make organic chemisty structures with LaTeX(in Winedt 
environment)? For example, to represent a carbonyl group, I need to you 
in text,  ">C=O", . I tried to use, the package ochem, but it needs perl 
as well as the manual is unfortunately in German. Is there any other 
package to do it?   Please let me know.

Much thanks in advance,

Zach.
