Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  N'ụzọ: A na-eme fatty acids site na fatty acid synthases nke na-eme ka polymerize wee belata nkeji acetyl-CoA. A na-agbatị agbụ acyl dị na fatty acids site na usoro mmeghachi omume nke na-agbakwunye otu acyl, belata ya na mmanya, wepụ ya na otu alkene wee belata ya ọzọ na otu alkane. A na-ekewa enzymes nke fatty acid biosynthesis n'ime ìgwè abụọ: na ụmụ anụmanụ na fungi, a na-eme ihe ndị a niile na-eme ka fatty acid synthase site na otu protein nke nwere ọtụtụ ọrụ, ebe ọ bụ na plastik osisi na nje bacteria dị iche iche ụdị II enzymes na-eme usoro ọ bụla n'okporo ụzọ.Terpenes na isoprenoids bụ nnukwu klas nke lipids nke gụnyere carotenoids ma mepụta klas kachasị ukwuu nke ngwaahịa sitere na osisi. A na - emepụta ogige ndị a site na nchịkọta na mgbanwe nke isoprene nkeji nyere site na ndị na - ebute ụzọ isopentenyl pyrophosphate na dimethylallyl pyrophosphate. E nwere ụzọ dị iche iche e si emepụta ihe ndị a. N'ime anụmanụ na archaea, ụzọ mevalonate na-emepụta ogige ndị a site na acetyl-CoA, ebe osisi na nje bacteria na-eji ụzọ na-abụghị mevalonate na-eji pyruvate na glyceraldehyde 3-phosphate dị ka substrates. Otu ihe dị mkpa nke na-eji ndị a na-enye isoprene arụ ọrụ bụ biosynthesis steroid. N'ebe a, a na-ejikọta isoprene n'otu n'otu iji mepụta squalene, e mesịakwa, a na-apịkọta ha ọnụ ma mepụta mgbanaka iji mepụta lanosterol. Lanosterol nwere ike gbanwee n'ime steroid ndị ọzọ dị ka cholesterol na ergosterol.  Ajụjụ: Gịnị bụ ọkwa ikpeazụ nke isoprene nkeji nke nwere ike ghọọ cholesterol na ergosterol?
