Peptid-Metall-Komplex: Mit der NMR-Spektroskopie klärte das Bochumer Forscherteam die dreidimensionale Struktur eines Peptid-Metall-Komplexes auf. Das Metallatom, Rhodium (pink), bindet an die Aminosäure Tyrosin des Peptids, genauer gesagt an den Phenolring – eine Struktur aus sechs Kohlenstoffatomen (grün), einem Sauerstoffatom (rot) und Wasserstoffatomen (nicht gezeigt). Der zweite Kohlenstoffring (grün) über dem Rhodium ist eine Pentamethylcyclopentadienyl-Gruppe. Rhodium ist über eine sogenannte Metallkoordinationsbindung zwischen den beiden Kohlenstoffringen gebunden. Das graue Netz symbolisiert die Moleküloberfläche.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
