To link to the content of EndoNet use the EndoNet ID that is given on the detail
        pages in the format ENX0000, where X is a place holder for the type of
        the component (e. g. R for receptor or C for anatomical structure). 
        As URL
        for the linking append this ID to the detail page for this type of component.
        For an hormone that would be: 
http://endonet.bioinf.med.uni-goettingen.de/hormone/ENH00000
        It is also possible to use the search of EndoNet to link to the right detail
        page. The URL should look like 
http://endonet.bioinf.med.uni-goettingen.de/search/ENC00000
        If the search pattern is unambigious the user is directed to the corresponding
        detail page.
