 Title    Interconversion of Prenyl Pyrophosphates and Subsequent Reactions in the Presence of FMC 57 020  
 Abstract    In vitro studies o f the influence o f FMC 57020 on terpenoid biosynthesis have shown that this herbicide acts at an early stage. It affects the conversion of isopentenyl pyrophosphate to geranylgeranyl pyrophosphate catalyzed by isopentenyl pyrophosphate isomerase and prenyl transferase. An inhibition o f the carotenogenic enzym es phytoene desaturase, ^-carotene desatur-ase, and lycopene cyclase could be excluded. Comparison of ho values for in vivo chlorophyll, carotenoid, ergosterol and gibberellin biosyn­ thesis as well as in vitro formation o f phytoene, phytol and kaurene in various autotrophic and heterotrophic organism s have shown that terpenoid biosynthesis in the chloroplast is much stronger affected than extraplastidic terpenoid formation.

 Title    American Alligator (Alligator mississippiensis)  
 Abstract    Lipids from the gular glands of the American alligator (Alligator mississippiensis) were examined by gas chromatography-mass spectroscopy. C14, C|6, and C 18 fatty acids, squalene, and a-tocopherol (vitamin E) were detected in nearly all samples. Cholesterol was detected clearly in several samples.
