Try doing a Google search on "define:molecule".
Or Google "source of molecues"/"function of molecules", etc.
Does that help you?
Where can I find info on molecules; i.e., where they come from, their function, what they do for our body...

Molecules are composed of atoms. Here is a site that give some discussion of where molecules come from and some of their uses.
Sorry, I didn't post the site.
