 Title    The Structures of Sinapic Acid Esters and Their Metabolism in Cotyledons of Raphanus sativus  
 Abstract    Five sinapic acid esters were isolated from cotyledons of Raphanus sativus and have been iden­ tified with the aid of electron impact (El)-, field desorption (FD)-mass spectrometry and NMR spectroscopy: 6,3'-disinapoylsucrose, sinapoylcholine (sinapine), 6 -sinapoylglucoraphenine, 1 -si­ napoylglucose, and sinapoylmalate. Three of these derivatives are metabolically related in the se­ quence sinapoylcholine -» • 1 -sinapoylglucose — ► sinapoylmalate.

 Title    Hydroxycinnamoyl Esters of Malic Acid in Small Radish {Raphanus sativus L. var. sativus)  
 Abstract    The esters o f /?-coumaric, ferulic and caffeic acid with m alic acid were isolated from leaves, the ester o f sinapic acid with m alic acid from cotyledons o f Raphanus sativus plants via prepara­ tive HPLC. The esters were identified by hydrolyses and follow ing capillary G C , by H -N M R and FAB-MS. Their concentrations in leaves and tubers were determ ined by gradient HPLC on reversed phase material.

 Title    Inhibition of Plant Acetyl-Co A Synthetase by Alkyl-adenylates  
 Abstract    The plant acetyl-C oA synthetase (A CS) is bound to the plastids and provides acetyl-CoA, the starting substrate for de novo fatty acid biosynthesis in plastids. This enzymic reaction, which consumes ATP and releases A M P, can be inhibited by different alkyladenylates such as ethyl-, isopropyl-, propyl-or allyl-adenylates as is shown here. The inhibition mechanism is competitive with respect to ATP and non-com petitive with respect to acetate. I50-values and the inhibition constants K((ATP), K ((acetate) and K^ (acetate) are given. The results suggest that, also in plants, acetyl-adenylate is the endogenous intermediate in the enzymic formation o f acetyl-CoA from acetate by acetyl-CoA synthetase.
