Mō te tiaki kiri whai hua, he mea nui kia whai ariā motuhake mō ngā kai, ehara i te mea ko te whakatairanga i te hua anake, engari ko ngā kai hoki o te hua. I tēnei rā, me kōrero tātou mō te "carnosine" o ngā kai o ngā hua tiaki kiri.
He aha te 'Carnosine'
He dipeptide te Carnosine, he mea tito mai i te beta-alanine me te L-histidine, he nui te ihirangi i roto i ngā uaua me ngā aukati roro. He nui ngā āhuatanga antioxidant o te Carnosine, ā, ka taea e ia te tango i ngā rauropi kore utu i roto i te tinana.
Te mahi a te 'carnosine'
Ka taea e te Carnosine te whakanui ake i te ātete o te kiri, te pupuri i te āhua taitamariki o ngā pūtau mā te pupuri i te mahi a ngā pūtau i roto i te roopu whānuitanga katoa me ngā āhuatanga rauropi kore utu, te whakatairanga i te hanga collagen, me te pupuri i te kiri kia ngāwari.
Te mahi a te 'carnosine'
Ka taea e te Carnosine te whakanui ake i te ātete o te kiri, te pupuri i te āhua taitamariki o ngā pūtau mā te pupuri i te mahi a ngā pūtau i roto i te whānuitanga katoa me ngā āhuatanga rauropi kore utu, te whakatairanga i te hanga collagen, me te pupuri i te kiri kia ngāwari. Ko te āhua matū oL-carnosineKo te hanganga o te beta-alanine me te L-histidine mā te mahi a te carnosine synthase. He whānui ngā tono a Carnosine i roto i ngā mara o te rongoā, te tiaki hauora, me te akuaku nā ōna āhuatanga antioxidant, ngā pānga whakakore i ngā rauropi kore utu, te chelation me ngā konganuku whakawhiti, te tiaki io, te whakatairanga i te whakaora patunga, me te ārai i te koroheketanga.
1. Te whakamahinga o te carnosine i roto i te umanga kai
Ko te wāhanga matua o te hinu i roto i te kai he ranunga o ngā momo glycerides waikawa ngako. Nā te tauhohenga rauropi kore utu o ngā glycerides waikawa ngako kore kukū i te wā rokiroki, ka puta ngā peroxides me ngā aldehydes kakara, ngā waikawa carboxylic rānei me ngā mekameka waro poto. Nō reira, mā te kai i ngā kai kei roto ngā peroxides ngako ka whakatairanga ake i te peroxidation lipid i roto i te tinana o te tangata, ka puta ai ngā mate maha. Nō reira, he maha ngā wā ka whakamahia te butylated hydroxyanisole, te dibutylated hydroxytoluene, te propyl gallate, me ētahi atu i roto i te tukatuka me te rokiroki kai hei ārai i te peroxidation ngako, engari ka heke te whai huatanga i roto i te tukanga whakamahana o te tukatuka kai, ā, he paitini tōna. Kāore e taea e te L-carnosine te aukati i te whakakōkī ngako anake, engari he nui hoki ngā mahi haumaru me te tiaki hauora. Nō reira, he antioxidant kai whai hua, he pai hoki te L-carnosine.
2. Te whakamahinga o te carnosine i roto i te rongoā me te tiaki hauora
(1) Carnosine me te Antioxidant
Kāore e taea e Carnosine te whakamahi i te mowhiti imidazole N atom me te peptide bond N atom i runga i ngā toenga histidine hei here i ngā katote whakarewa me te aukati i te waikura ngako i puta mai i ngā katote whakarewa, engari ko te histidine i te mekameka taha o te carnosine he kaha ki te hopu i ngā rauropi hydroxyl. Ka taea e ia te aukati i te waikura o te ngako i puta mai i ngā katote kore-whakarewa. Nō reira, hei matū hohe antioxidant maha-mahi, ka taea e carnosine te tiaki pumau i te membrane pūtau, ā, he kaihoroi rauropi kore utu wairewa-wai. , ka taea te aukati i te peroxidation o te membrane pūtau. Ki te whakatauritea ki ētahi atu antioxidants koiora pēnei i te VC, he kaha ake te kaha antioxidant o te carnosine. Haunga te aukati i te tukanga peroxidation o te membrane pūtau, ka taea hoki e carnosine te aukati i te raupapa o ētahi atu tauhohenga peroxidation intracellular, arā, ka taea e carnosine te aukati i ia taahiraa o te tauhohenga waikura i roto i te mekameka peroxidation katoa i roto i te rauropi. Ko te mahi a ngā antioxidants pēnei i te VC he ārai i ngā rauropi kore utu kia kaua e uru ki roto i te kiko, arā, ka taea anake e rātou te ārai i te tukanga peroxidation wai o te kiriuhi pūtau, ā, kāore e taea te mahi i tetahi mea mō ngā rauropi kore utu kua uru ki roto i te pūtau.
(2) Carnosine me te mate puku
He mate puku mau tonu te mate puku peptic o te ao whānui, ā, kāore anō kia tino mārama ngā āhuatanga motuhake e puta ai ngā puku i tēnei wā, engari e whakapono ana te pathology ko ngā āhuatanga whakaeke (pēnei i te waikawa puku, te huna pepsin, te mate Helicobacter pylori) me te ārai, te ārai pūtau rānei i puta mai i te kore taurite o ngā āhuatanga tiaki (te huna hūpē, te huna paikāponate, te hanga prostaglandin). Ko te tikanga tiaki taiao o te puku ko: ka hangaia he paparanga matotoru o te kiriuhi puku e mahi ana hei ārai tiaki hei tiaki i ngā pūtau i roto i te arai. Mā te huna tonu o te kiriuhi mucous ka tiaki i te puku, engari ko te huna nui ka puta he puku puku. Kua kitea e ngā rangahau ka taea e te zinc-carnosine te tango me te kai te ārai pai i ngā puku, ka taea te pupuri i te pono o te puku me tana tikanga tiaki taiao, nā ngā āhuatanga antioxidant o te carnosine, te pumau o te kiriuhi, te whakahaere i ngā āhuatanga Pharmacological o te ārai mate me te whakatika i ngā kiko. E ai ki ngā whakamātautau haumanu, i muri i te tango i te zinc-carnosine mō ngā wiki e waru, 70% o ngā tūroro i tango i te rongoā i whakaatu i te whakapainga nui, ā, 65% o ngā puku puku i whakapaingia mā te gastroscopy.
(3) Te Carnosine me te whakahaere i te ārai mate
Ko te urupare ārai mate he mahi ā-tinana e pupuri ana i te homeostasis, ā, e whakahaeretia ana e ngā matū hohe ā-tinana i roto i ngā mea ora. Ko ngā immunomodulators e pā ana ki te maimoatanga o tētahi momo mate e puta mai ana i te ngoikore o te ārai mate, ā, e whakamahia ana hei whakaora i te urupare ārai mate, hei aukati i tōna hekenga rerekē, hei pehi rānei i tōna urupare tere. Ko te nuinga o ngā immunomodulators o nāianei ka hangaia mā ngā tikanga hanga matū, he pānga paitini me ngā pānga taha. Kua whakaatuhia e ngā rangahau he mahi immunomodulatory tā te carnosine, ā, koinei anake te matū hohe ā-tinana kua kitea tae noa ki tēnei wā mō te immunomodulation, ā, kua whakamahia whānuitia hei rongoā i ngā mate me ngā mate ārai mate rerekē e puta mai ana i te ārai mate rerekē.
