29. Labels. Suppose that you had an in vitro fatty acid- synthesizing system that had all of the enzymes and cofactors required for fatty acid synthesis except for acetyl CoA. To this system, you added acetyl CoA that contained radioactive hydrogen (³H, tritium) and carbon 14 (¹4C) as shown here. 3H O 14 3H-C-C-SCOA 3H The ratio of ³H/¹4C is 3. What would the 3H/14C ratio be after the synthesis of palmitic acid (C₁6) with the use of the radioactive acetyl CoA?
