Description: The next several reactions occur in the cytosol. First, mevalonate is activated by three successive phosphorylations. The first two are simple nucleophilic substitutions on the g-phosphorous of ATP. The third phosphorylation, at position 3, sets the stage for a decarboxylation to give the five-carbon isopentenyl pyrophosphate Picture Stats: Views: 180 Filesize: 71.95kB Height: 425 Width: 728 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=34675 |
