Sugar fatty acid esters pathways

Analysis of Labeled Acyl Groups. Deuterated branched chain amino acids were all incorporated at extremely high rates into sugar ester acyl groups, an indication of the active nature of this pathway. In some instances the amount of deuterium labeled fatty acids exceeded (146%) that of the unlabeled material remaining on the leaf surface (10-20% of the original amount of glucose ester). GC/MS data for labeled 3-methylbutyrate from the incubation of [dio] Leu are shown in Fig. 2. As...
