Iyini i-Polyhydroxybutyrate PHB ene-CAS 26744-04-7?

I-PHB ikhiqizwa yizinto ezincane, ngokusobala ngenxa yezimo zokucindezeleka ngokomzimba. Ngokuyinhloko iyisimo sezakhamzimba ezilinganiselwe. I-polymer ngokuyinhloko ingumkhiqizo wokuhlanganiswa kwekhabhoni (kusuka ku-glucose noma isitashi) futhi isetshenziswa yizinto ezincane njengendlela yokwakheka kwemolekyuli yokugcina amandla ukuze kusetshenziswe i-metabolism lapho eminye imithombo yamandla evamile ingatholakali.

Isicelo

I-PHB inezindlela eziningi zokusebenzisa izinto zokwelapha, amapulasitiki abolayo, izitsha zokudla ezilahlwayo, ozimele bemibukiso, ukupakishwa, ukwelashwa kwendle, amathoyizi kanye neminye imikhakha.
Ezolimo: isithwali esibolayo samafilimu ezolimo, izibulala-zinambuzane ezisebenza isikhathi eside kanye nomanyolo
Imithi: Imishini yokuhlinzwa, izinzipho zendololwane, ukushintshwa kwamathambo, ukushintshwa kwemithambo yegazi Imboni: izinto zokupakisha, imikhiqizo yokuhlanzeka, amanabukeni, izinto ezisebenzayo ezibonakalayo
Emkhakheni wezinto zokwelapha, i-polyhydroxybutyrate ingasetshenziswa ukulungiselela izinto zokuthwala izidakamizwa ezikhishwa njalo, izinto zobunjiniyela bezicubu, njll. Emkhakheni wokupakisha, imikhiqizo yokuwohloka kwe-polyhydroxybutyrate ikakhulukazi i-carbon dioxide namanzi, okuhambisana nomqondo wamanje wokuthuthukiswa kokuvikelwa okuluhlaza nokwemvelo.
