Re: RE: Hybd- Pink and yellow

Neil,
I have a book called Biochemistry and Molecular Biology of Plants that touches on this. It looks like lycopene is synthesized from phytoene (precursor to all carotenoids) via 4 desaturation reactions involving 2 enzymes. Then lycopene is cyclized on the ends to form either beta-carotene (enzyme = lycopene beta-cyclase) or alpha-carotene (enzymes = lycopene beta-cyclase + lycopene epsilon-cyclase). Then other products are made from those.
Is that any help?

Chuck, I was fascinated with your brief remarks about the synthesis of yellow
with Lycopene early, the conversion to carotenes following. I'd like to know
about those articles you've run across--what a world of ideas this opens up!
Given the shapes of the molecules this makes a lot of sense.
