Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mafuta acids anogadzirwa nemafuta acid synthases ayo polymerize uye ipapo kuderedza acetyl-CoA zvikamu. Maketani eacyl ari mumafuta eacid anowedzerwa nechikamu chezviito zvinowedzera boka reacyl, kuriita kuti rive doro, kuriita kuti rive boka realkene uyezve kuriita kuti rive boka realkane. Maenzayimu efatty acid biosynthesis akapatsanurwa kuva mapoka maviri: kumhuka nefungus, ese aya maf fatty acid synthase reaction anoitwa neprotein imwechete yemhando I, nepo mumiti yeplastids nemabhakitiriya maenzayimu akaparadzana erudzi rwechipiri anoita nhanho yega yega munzira. Terpenes uye isoprenoids kirasi hombe yema lipids inosanganisira ma carotenoids uye inoumba kirasi hombe yezvigadzirwa zvechisikigo zvemiti. Aya makemikari anogadzirwa nokuunganidza uye kuchinja zvikamu zve isoprene zvinopiwa kubva kune zvinoshandiswa zvinoshandiswa isopentenyl pyrophosphate uye dimethylallyl pyrophosphate. Zvinhu izvi zvinogona kugadzirwa nenzira dzakasiyana. Muzvipfuyo nemarchaea, nzira ye mevalonate inogadzira makemikari aya kubva kuacetyl-CoA, nepo muzvirimwa nemabhakitiriya nzira isiri ye mevalonate inoshandisa pyruvate uye glyceraldehyde 3-phosphate semasubstrates. Chimwe chinhu chinokosha chinoshandiswa nevanopa isoprene iyi inoshanda inonzi steroid biosynthesis. Pano, zvikamu zveisoprene zvinobatanidzwa pamwe chete kuti zviite squalene uye zvino zvakapetwa ndokuumbwa kuva seti yemhete kuti zviite lanosterol. Lanosterol ipapo inogona kuchinjwa kuva mamwe steroid akadai secholesterol uye ergosterol.  Mubvunzo: Ndeipi iri nhanho yokupedzisira yezvikamu zveisoprene zvinogona kushandurwa kuva cholesterol neergosterol?
lanosterol
