Re: gluconeogenesis from pyruvate--> labeling carbon

When the two triosephosphates condense head-to-head to form a hexose, carbon 1 of the triose (originating from the carboxyl of pyruvate) forms carbons 3 and 4 of the hexose, carbon 2 of the triose forms carbons 2 and 5 of the hexose, and carbon 3 of the triose forms carbons 1 and 6 of the hexose.
