4. Consider the role of the pantothenic acid groups in animal fatty acyl synthaseand the size of the pantothenic acid group itself, and estimate a maximalseparation between the malonyl transferase and the ketoacyl-ACP synthase activesites.5. Carefully study the reaction mechanism for the stearoyl-CoA desaturase inFigure 24.14, and account for all of the electrons flowing through the reactionsshown. Also account for all of the hydrogen and oxygen atoms involved in thisreaction, and convince yourself that the stoichiometry is correct as shown.
