The biosynthesis of cyclic carotenes [PDF]
Biochemical Journal, 1967 1. The incorporation of (3RS)-[2−14C,(4R)-4−3H1]mevalonic acid into various cyclic carotenes in the fruit of the tomato mutant delta has been studied. The results confirm our previous view that the α-ionone ring of α-carotene does not arise by isomerization of a β-ionone residue, and show that the same is also true for the α-ionone ring of δ- and ...

Metabolism of Alpha-carotene [PDF]
Nature, 1966 IN the course of an earlier investigation into the utilization of carotene by the rat as a source of vitamin A, it was noted that there was a consistent difference between the absorption spectra of the liver non-saponifiable fractions from those rats fed vitamin A and those fed a mixture of 90 per cent beta- and 10 per cent alpha-carotene1.
