the carotene molecule, and the position of this key carbon in the Cg repeating unit of carotene can readily be envisaged. Whether leucine provides an is0 C B fragment cannot be determined as yet, but it is clear that the stimulatory effect of leuciue on carotene formation is due to the incorporation of leucine fragments into the molecule.
