| 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. | | | |

| 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. | | | |

| 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. | | | |
