4. Oxaloacetate uniformly labeled with 14C (ie with equal amounts of 14C in each of its carbon atoms) is condensed with unlabeled acetyl-CoA. After a single pass through the citric acid cycle back to oxaloacetate, what fraction of the original radioactivity will be found in the oxaloacetate?
Question: You buy a sample of glucose that has the radioactive carbon-14 (C) isotope at the second position (Carbon #2). All other carbon positions in the glucose molecules have the "C isotope. "C is only a label and does not alter the biochemical behavior of the molecules in which it is found. This glucose sample is mixed with all the enzymes derived from liver cells, which initially contain no other C-labeled chemicals. A) Draw the Haworth structure of glucose and...
