Don't know. We can only generalize. Depending on how hard you rode at various times a certain amount of your energy came from fat and some from glycogen that can be more readily replaced by carbohydrate. You almost always are burning a certain amount of fat. Glycogen comes into play more as you exceed the rate at which your body can convert fat to energy.
Whether any of that was from the molecules that made up your Jasmine rice I'd not even begin to speculate. <grin>
