ParāoaHe matū polyamine nui te spermine e kitea whānuitia ana i roto i ngā rauropi, inā koa he mahi nui tāna i roto i te tipu me te horapa o ngā pūtau. Ka hurihia te parāone mai i ngā waikawa amino arginine me te ornithine. Ka tūhuratia e tēnei tuhinga te pūtake, te mahi me te hiranga o te parāone i roto i ngā rauropi.
Ngā Pūtake o te Parāoa
Ko te hanganga o te parāmine e whakawhirinaki ana ki te pākia o ngā waikawa amino. Tuatahi, ko te ornithine te matū o te hanganga parāmine, ka taea te whakaputa mā te tauhohenga decarboxylation o te arginine. Ko te tukanga motuhake e whai ake nei:
Ka hurihia te arginine hei ornithine: I raro i te whakaterenga a ngā whākōkī, ka wetewetehia te carboxylation o te arginine hei hanga i te ornithine.
Te huringa o te ornithine ki te parāoa: Ka honoa anō te ornithine ki tētahi waikawa amino (ko te waikawa amino alanine te tikanga) ā, mā roto i tētahi raupapa o ngā tauhohenga whākōkī, ka hangaia he parāoa.
Ehara i te mea ko te pākia o ngā waikawa amino anake te mea e pā ana ki tēnei tukanga tahuritanga, engari he hononga tata anō hoki ki te tipu, te wehenga me te whakatikatika pūtau.
Ngā pānga koiora o te parāoa
He maha ngā mahi koiora nui a te parāmine i roto i ngā rauropi, tae atu ki ēnei āhuatanga matua:
Te tipu me te horapa o ngā pūtau: He mea nui te mahi a te parāoa i roto i te whakahaere i te huringa pūtau. Kua whakaatuhia e ngā rangahau ka taea e te parāoa te whakatairanga i te horapa o ngā pūtau, inā koa i roto i te tukanga whakatikatika me te whakaora kiko. Ka whakatairanga i te wehenga me te tipu o ngā pūtau mā te whakahaere i te whakaaturanga o ngā pūmua e pā ana ki te huringa pūtau.
Pānga ārai-waikura: He āhuatanga ārai-waikura kei roto i te parāmine, ka taea te tango i ngā rauropi kore utu i roto i te tinana, me te whakaiti i te kino ki ngā pūtau i puta mai i te ahotea waikura. Nā tēnei āhuatanga ka whai hua pea te parāmine ki te whakaroa i te koroheketanga me te ārai i ngā mate e pā ana ki te koroheketanga.
Te whakahaere i te whakaaturanga ira: Ka taea e te parāoa te whakahaere i te whakaaturanga ira mā te herea ki te DNA me te RNA. He mea nui tēnei pānga whakahaere mō te mahi a te pūtau me te āhua o te tinana, inā koa hei whakautu ki ngā whakaohooho me te ahotea o waho.
Ka whakatairanga i te apoptosis: I raro i ētahi āhuatanga, ka taea hoki e te parāmine te whakatairanga i te apoptosis (te mate pūtau kua whakaritea), he mea nui mō te pupuri i te homeostasis pūtau me te hauora o te kiko.
Te Whakarerekētanga Ārai Mate: He mahi nui anō tā te parāoa i roto i te pūnaha ārai mate. Ka taea e ia te whakarei ake i te mahi a ngā pūtau ārai mate me te whakapai ake i te ātete o te tinana ki ngā mate urutā me ngā mate.
Te Parāoa me te Hauora
I te hohonu haere o ngā rangahau mō te parāoa, kei te piki haere ngā taunakitanga e whakaatu ana he hononga tata te parāoa ki ngā momo raruraru hauora. Hei tauira, he hononga tata ngā taumata parāoa ki te putanga mai me te whanaketanga o ngā momo mate pēnei i te koroheketanga, te mate manawa, me te mate pukupuku.
Te koroheketanga: Kua kitea e ngā rangahau ka heke haere ngā taumata parāoa i te wā e koroheke ana, ā, mā te tāpiri i te parāoa ka āwhina pea i te whakaroa i te koroheketanga me te whakapai ake i te hauora o ngā kaumātua.
Hauora o te Ngākau: He mahi tiaki tā te parāoa i roto i te pūnaha ngakau, e whakapai ake ana i te mahi endothelial me te whakaiti i te mōrearea o te mate ngakau.
hei whakamutunga
Hei ngota koiora nui, ko te nuinga o te wā ka ahu mai te parāmine i te pākia o ngā waikawa amino, inā koa te hurihanga o te arginine me te ornithine. He mahi nui tā te parāmine ki te whakatipu pūtau, ki te ārai i te waikura, ki te whakahaere i te whakaaturanga ira, me ētahi atu, ā, he mea nui hoki mō te pupuri i te hauora me te mahi a ngā rauropi. Mā te rangahau hohonu o te parāmine, tera pea ka kitea ētahi atu kōrero mō tōna mahi ki te hauora me te mate a muri ake nei, ka puta mai he whakaaro me he tikanga hou mō te ārai me te rongoā i ngā mate e pā ana.
Mā te mārama ki te takenga mai me te mahi a te parāoa, ka taea e tātou te mārama ake ki tōna hiranga i roto i ngā mahi o te ao, ā, ka whakaratohia he pūtake pūtaiao hei whakatairanga i te hauora me te whakaroa i te koroheketanga. Ko te tumanako ka hurahia ake e ngā rangahau ā muri ake nei ngā whakamahinga pea o te parāoa, ā, ka nui ake ngā takoha ki te hauora o te tangata.
Whakakape: Ka whakaputa, ka tāia anō rānei tēnei tuhinga e tēnei paetukutuku hei tuku me te tohatoha atu i ētahi atu kōrero, ehara i te mea e whakaae ana ki ōna tirohanga, e whakaū ana rānei i tōna whakaahuatanga. Mena he hapa kei roto i te tohu pūtake, he takahi rānei i ō mana ture, tēnā whakapā mai ki tēnei paetukutuku me te whakaatu i te mana pupuri, ā, ka whakatikahia, ka mukua rānei e mātou i te wā tika. Ngā mihi.
Whakakape: He kōrero whānui noa iho tēnei tuhinga, kaua e whakamāramatia he tohutohu hauora. Ko ētahi o ngā kōrero o te pou rangitaki i ahu mai i te Ipurangi, ehara i te mea ngaio. Ko tā tēnei paetukutuku anake he whakarōpū, he whakatakotoranga me te whakatika i ngā tuhinga. Ko te kaupapa o te kawe atu i ētahi atu kōrero, ehara i te mea e whakaae ana koe ki ōna tirohanga, e whakaū ana rānei i te pono o ōna ihirangi. Me kōrero tonu ki tētahi tohunga hauora i mua i te whakamahi i tētahi tāpiringa, i te hanga rānei i ngā huringa ki tō tikanga tiaki hauora.
