- ↑ 5cts as the state preceding condensation with oxaloacetate and a non-reactive version of acetyl-CoA bound, 6cts as the state containing the bound intermediate, and 3cts as the complex with the products. Positions of hydrogens on the ligands were calculated and added back to structures in the reaction scheme for instructional purposes and are not present in the experimentally-determined structures; additionally, arrows are drawn with atoms of the analog of acetyl-CoA to approximate the position of the reactive groups only as the reactive groups are not actually part of the analog or the molecules would have reacted; please, see the reaction scheme on this page for a more thorough accounting of the chemistry.
