Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te biosynthesis unconditioned o te lycopene i roto i nga tipu eukaryotic me nga cyanobacteria prokaryotic he rite, pera ano me nga enzyme e uru ana. Ka tīmata te whakahiato ki te waikawa mevalonic, ka hurihia ki te dimethylallyl pyrophosphate. I muri mai ka whakakotahihia ki nga ngota e toru o te isopentenyl pyrophosphate (he isomer o te dimethylallyl pyrophosphate), kia whiwhi i te 20-carbon geranylgeranyl pyrophosphate. E rua ngā rāpoi ngota o tēnei hua ka kōpeke i roto i te whirihoranga hiku-ki-ngakau ki te hoatu i te phytoene 40-carbon, te taahiraa tuatahi i roto i te carotenoid biosynthesis. Na roto i nga waahanga whakaheke, ka hurihia te phytoene ki te lycopene. Ko nga roopu isoprene mutunga e rua o te lycopene ka taea te huri ki te whakaputa beta-carotene, ka taea te huri hei momo momo xanthophylls.  Pātai: He aha te mea ka tupu ki te phytoene i muri i te whakahekenga?
ka huri ki te lycopene
