Te Mahi me te Whakamahinga o te N-Acetyl-L-Tyrosine (Ac-Tyr-OH; NALT) (CAS: 537-55-3) paura
1. Ko te N-Acetyl-L-Tyrosine he acetyl derivative o te waikawa amino, L-tyrosine.He wairewa noa ki te wai ka whakatauritea ki te L-tyrosine, ka whakamahia hei taapiri kai ma te matua.Ko te N-Acetyl-L-Tyrosine, he ahua pumau me te whakarewa ake o te tyrosine, kua whakauruhia ki roto i etahi hanganga waikawa amino parenteral arumoni e waatea ana i tenei wa penei i te TrophAmine me Aminosyn-II.
2. Ko te N-Acetyl-L-Tyrosine kei roto i te hanga catecholamine.Ka taea te whakamahi hei waahanga pāpāho ahurea pūtau i roto i te hanga koiora arumoni o nga pūmua recombinant rongoa me nga paturopi monoclonal.
3. N-Acetyl-L-Tyrosine he waikawa amino tino nui, he momo kai nui mo te tangata me te kararehe, he mea nui te tipu me te whanaketanga, ka taea te whakamahi whanui ki te kai, ki te rongoa etc.
4. Ko te N-Acetyl-L-Tyrosine he waahi e tika ana mo te whakahiato o te dopamine me etahi atu homoni i roto i to tinana.Ka taea te whakanui i nga taumata o te dopamine, te norepinephrine me te epinephrine.Ka awhina ki te tautoko i nga taumata teitei o te arotahi me te mahi hinengaro.Ka taea te whakanui ake i te mahara mahi me nga kare o te oranga.
5. Kua whakarerekētia te N-Acetyl-L-Tyrosine mai i te Tyrosine noa na te mea kei roto te taapiri o te waikawa ahetiki.Ka tino awhina tenei ki te whakanui ake i te koiora o te puhui kia pai ake ai te uru ki roto i te toto.
6. Ko te N-Acetyl-L-Tyrosine he momo tino koiora o te L-Tyrosine mo te maimoatanga o mua o nga ahuatanga iti ka taea te whakamahi i te N-Acetyl-L-Tyrosine ki nga pota iti ake i te L-Tyrosine.Ko te L-Tyrosine noa he iti ake te pumau me te kore e rewa i roto i te wai, tera pea ka iti ake te koiora.
7. Ko te N-Acetyl-L-Tyrosine te whakanui ake i te wairewa me te pumau kia tere ake te uru me te koiora o te waikawa amino L-Tyrosine he iti ake te whakaraerae ki te whakaheke mimi.
