Alpha-ketoglutarate (AKG muchidimbu) chinhu chakakosha chemetabolism chinoita basa guru mumuviri wemunhu, kunyanya mumetabolism yesimba, antioxidant response, uye kugadzirisa masero.
Mumakore achangopfuura, AKG yave ichinyanya kutariswa nekuda kwekugona kwayo kunonoka kukwegura nekurapa zvirwere zvisingaperi. Heano maitiro chaiwo ekushanda kweAKG mumaitiro aya:
AKG inoita mabasa akawanda mukugadzirisa DNA, ichibatsira kuchengetedza kusimba kweDNA nenzira dzinotevera:
Sechinhu chinobatanidza hydroxylation reactions: AKG ichinhu chinobatanidza oxygenases dzakawanda (dzakadai seTET enzymes nemaPHDs enzymes).
Ma enzyme aya anobatanidzwa mukubvisa methylation yeDNA uye kuchinja histone, kuchengetedza kugadzikana kwe genome uye kudzora kuratidzwa kwemajini.
Enzayimu yeTET inokonzeresa kubviswa kwemethylation ye5-methylcytosine (5mC) uye inoishandura kuita 5-hydroxymethylcytosine (5hmC), nokudaro ichidzora kuratidzwa kwemajini.
Nekutsigira mashandiro ema enzyme aya, AKG inobatsira kugadzirisa kukuvara kweDNA uye kuchengetedza kusimba kwe genome.
Mhedzisiro yeAntioxidant: AKG inogona kuderedza kukuvara kweDNA kunokonzerwa nekushushikana kweoxidative nekubvisa mafree radicals uye reactive oxygen species (ROS).
Kushushikana kwemasero (oxidative stress) chinhu chakakosha chinotungamira mukukuvadzwa kweDNA uye kukwegura kwemasero. Nekuwedzera kugona kwemasero ekudzivirira mabhakitiriya, AKG inogona kubatsira kudzivirira kukuvara kweDNA kwakabatana nekushushikana kwemasero.
Gadzirisa masero nematishu
AKG inoita basa rakakosha mukugadzirisa masero uye kudzoreredza tishu, kunyanya kuburikidza nenzira dzinotevera:
Kusimudzira mashandiro emasero ekutanga: AKG inogona kuwedzera mashandiro uye kugona kwemasero ekutanga. Tsvagiridzo inoratidza kuti AKG inogona kuwedzera hupenyu hwemasero ekutanga, kukurudzira kusiyana kwawo uye kuwanda kwawo, uye nokudaro ichibatsira mukuvandudzwa nekugadzirisa kwenyama.
Nekuchengetedza mashandiro emasero emuviri, AKG inogona kunonotsa kukwegura kwenyama uye kuvandudza kugona kwemuviri kudzoreredza hutano.
Kuvandudza metabolism yemasero uye autophagy: AKG inobatanidzwa mu tricarboxylic acid cycle (TCA cycle) uye chigadzirwa chakakosha chepakati che metabolism yesimba remasero.
Nekuwedzera kushanda zvakanaka kweTCA cycle, AKG inogona kuwedzera simba remasero uye kutsigira kugadziriswa kwemasero uye kuchengetedza mashandiro awo.
Pamusoro pezvo, AKG yakawanikwa ichikurudzira maitiro e autophagy, ichibatsira masero kubvisa zvinhu zvakakuvara uye kuchengetedza hutano hwemasero.
Kuenzana kwemajini uye mutemo we epigenetic
AKG inoita basa rakakosha mukuenzana kwemajini uye kurongeka kwe epigenetic, zvichibatsira kuchengetedza mashandiro akajairika uye hutano hwemasero:
Inokanganisa kurongeka kwe epigenetic: AKG inodzora maitiro ekutaura kwemajini nekutora chikamu mukuchinja kwe epigenetic, senge demethylation yeDNA nehistones.
Kudzora mageneti (epigenetic regulation) inzira huru yekutonga mashandiro emageneti uye mashandiro emasero. Basa reAKG rinogona kubatsira kuchengetedza mashandiro emageneti zvakanaka uye kudzivirira zvirwere nekukwegura zvinokonzerwa nekushandiswa kwemagene zvisina kujairika.
Dzima mhinduro yekuzvimba: AKG inogona kuderedza mhinduro yekuzvimba isingaperi inokonzerwa nekukwegura nekutonga kuratidzwa kwemajini.
Kuzvimba kusingaperi ndiko kunokonzera zvirwere zvakawanda zvinokonzerwa nekukwegura, uye migumisiro yeAKG inoderedza kuzvimba inogona kubatsira kudzivirira nekuderedza matambudziko aya.
Kunonoka kukwegura uye kurapa zvirwere zvisingaperi
Maitiro akawanda eAKG anoita kuti ikwanise kunonoka kukwegura uye kurapa zvirwere zvisingaperi:
Kunonoka kukwegura: Nekusimudzira kugadziriswa kweDNA, kuwedzera kugona kweantioxidant, kutsigira mashandiro emasero ekutanga, kudzora kugadzirwa kwemajini, nezvimwewo, AKG inogona kunonotsa kukwegura kwemasero nematishu.
Zvidzidzo zvemhuka zvinoratidza kuti kudya AKG kunogona kuwedzera hupenyu hwemhuka dzakura uye kuvandudza hutano hwadzo.
Kurapa zvirwere zvisingaperi: Migumisiro yeAKG mukuvandudza mashandiro emetabolism, kudzivirira kuzvimba, uye antioxidant inoita kuti ikwanise kubatsira mukurapa zvirwere zvisingaperi.
Semuenzaniso, AKG inogona kuva nemigumisiro yekudzivirira uye yekurapa pachirwere cheshuga, zvirwere zvemwoyo, zvirwere zve neurodegenerative, nezvimwewo.
Pfupisa
AKG inoita basa rekunonotsa kukwegura nekurapa zvirwere zvisingaperi nekugadzirisa DNA, kukurudzira kugadziriswa kwemasero nenyama, kuchengetedza kuenzana kwemajini uye kudzora epigenetics.
Kushanda pamwe chete kwemaitiro aya kunoita kuti AKG ive chinangwa chakanaka chekudzivirira kukwegura uye chirwere chisingaperi.
Mune ramangwana, tsvakiridzo yakawedzerwa ichabatsira kuratidza mamwe mabhenefiti anogona kuwanikwa eAKG pamwe nemikana yekushandisa kwayo.
Chiziviso: Chinyorwa ichi ndecheruzivo rwese chete uye hachifanirwe kutorwa semazano ekurapa. Mamwe emashoko eblog anobva paInternet uye haasi ehunyanzvi. Iyi webhusaiti ine basa rekugadzirisa, kuronga nekugadzirisa zvinyorwa chete. Chinangwa chekutumira rumwe ruzivo hazvirevi kuti unobvumirana nemaonero ayo kana kusimbisa chokwadi chezviri mukati mayo. Gara uchibvunza nyanzvi yehutano usati washandisa chero mishonga yekuwedzera kana kuita shanduko kuhurongwa hwako hwehutano.
