Talk:Phaseic acid

various problems

Biosynthesis - it would be better to move most of this section (except for the part from abscisic acid to phaseic acid) to the abscisic acid entry. Figure - Converting phytoene to b-carotene also involves desaturation. Carotenoid precursors - xanthoxin is produced by a dioxygenase not epoxygenase. Figure - b-carotene hydroxylase appears to convert b-carotene to zeaxanthin via cryptoxanthin rather than lutein. Figure - 9-cis is inconsistent with the structure shown. Modification of xanthoxin - Xanthoxin is oxidized at the alcohol, isomerized at the epoxy, and then oxidized at the aldehyde to produce abscisic acid. References - 4 should be (+)-abscisic acid 8'-hydroxylase. Should Epoxides be listed as a category? 69.72.92.164 (talk) 03:17, 26 December 2015 (UTC)
