Reorganising the article 
 In my opinion the article in its present form does not possess sufficient structure, covering biomolecules in too much detail and in an illogical way - e.g. 2 separate sections on proteins, while only treating metabolism in a small section under carbohydrates, and with very little on gene expression/regulation etc.. In addition it largely lacks any in-line referencing.  

 I've copied the article to a user page and am currently experimenting with a fairly substantial reorganisation, please feel free to  and discuss your thoughts on it.
