Ama-amino acid
1K 0 23.06.2019 (kugcine ukubuyekezwa: 24.08.2019)
I-Phenylalanine iyi-amino acid ebalulekile (ngemuva kwalokhu i-AA). Umzimba womuntu awukwazi ukwehluleka ukuzikhiqiza wedwa. Ngakho-ke, ukunikezwa kwe-AK okuvela ngaphandle kufanele kube njalo futhi kube yimiqulu eyanele. Kwezinye izimo, ukusetshenziswa okungeziwe kwezithako zokudla ngalesi sengezo kuyadingeka.
Izakhiwo zePhenylalanine
I-Phenylalanine itholakala kuma-protein amaningi futhi iyisandulela se-amino acid, i-tyrosine. Ngosizo lwe-tyrosine, i-pigment melanin ihlanganisiwe, enquma umbala wesikhumba futhi ivikele imisebe ye-ultraviolet. Futhi, ngosizo lwe-tyrosine, izinto eziningi eziphilayo ezisebenzayo zihlanganiswa, isibonelo, i-adrenaline, i-dopamine ne-norepinephrine, ama-hormone e-thyroid (umthombo - iWikipedia). Lezi zinto zidlala indima ebalulekile ekulawuleni isizinda somzwelo womuntu.
I-Phenylalanine kufanele isetshenziswe ngaphansi kweso eliqinile lezokwelapha. Le AK ikhonjiswa ikakhulukazi kubantu abakhuluphele ngenhloso yokunciphisa indlala (umthombo ngesiNgisi - iphephabhuku lesayensi i-Journal of the International Society of Sports Nutrition, 2017).

Imithamo nokusebenza kahle
Ngezinhloso zokwelapha, i-phenylalanine ne-DL-phenylalanine ingabekwa kumthamo we-0.35-2.25 g / ngosuku. L-phenylalanine 0.5-1.5 g / ngosuku Umthamo uncike ekuguleni okuthile.
Ukusebenza kwe-AK kufakazelwe ekwelapheni i-vitiligo, ngoba isebenza ukulawula ukukhiqizwa kwe-melanin (umthombo ngesiNgisi - iphephabhuku lesayensi iMacedonia Journal of Medical Sciences, 2018). Ukwengeza kwe-Phenylalanine kungasetshenziswa ekwelapheni ukucindezeleka ukwenza ngcono ukuhlanganiswa kwama-neurotransmitters alawula imizwa.
Ukuthatha i-phenylalanine kuyasebenza ezimweni ezilandelayo:
- ukuze wakhe umuzwa wokusutha (kweziguli ezikhuluphele);
- ukwelashwa kwe-vitiligo (kuqinisekisa ukuhlanganiswa okuvamile kwe-melanin);
- ukwelashwa kokucindezeleka (ukuqinisekisa ukuhlanganiswa kwe-adrenaline, norepinephrine ne-dopamine).
Izinhlobo ze-phenylalanine
Kunezinhlobo eziningi ze-AK okukhulunywa ngayo:
- I-DL-phenylalanine: inhlanganisela yezinhlobo L no-D. Iphumelela kakhulu ekulweni nokubonakaliswa kwe-vitiligo. Ikhuthaza ukwelashwa kokukhuluphala, kunikeza umuzwa wokugcwala.
- L-Phenylalanine: Ifomu Lemvelo. Inikeza ukukhiqizwa kwama-neurotransmitters. Isiza ukulwa nokukhathala nokuphazamiseka kwememori.
- I-D-phenylalanine: ifomu elenziwe elebhu elisetshenziswa ezimweni zokushoda kohlobo lwemvelo lwe-amino acid. Ibonisa ukusebenza kwe-antidepressant, ivuselela ukukhiqizwa kwama-neurotransmitters, futhi ilwe nokuphazamiseka kwemizwa.
Imithombo yemvelo ye-phenylalanine
I-AK imelwe kabanzi ekwakhiweni kwemikhiqizo yokudla ejwayelekile yemvelaphi yezilwane nezitshalo. Lokhu kuhlukahluka kuqinisekisa ukuthi ama-amino acid alethwa ngokwemvelo nsuku zonke.

Imiphumela emibi, ukugcwala ngokweqile nokushoda
Inani le-phenylalanine lomzimba womuntu alinakulinganiswa ngokweqile. Ngoba ukuntuleka kwayo kusongela ngezifo eziningi zomzimba. Okwakamuva kungabonakaliswa:
- ukukhubazeka kwememori;
- ukuncipha kokudla;
- ukukhathala okungapheli;
- ukuwela emanyaleni.
Ukuqongelela ngokweqile kwale AK akuyona ingozi kangako. Kunesifo esibi esibizwa nge-phenylketonuria. Lesi sifo sibangelwa ukungabikho kwe-enzyme ebalulekile (phenylalanine hydroxylase) noma ukukhiqizwa kwayo okuncane, okungazikhokhi izindleko zomzimba zokwehlukanisa. I-Phenylalanine iqongelela ngenxa yalokho umzimba kungenzeka ungabi naso isikhathi sokudiliza le AA ezintweni ezidingekayo bese uyisebenzisa ekwakheni amaprotheni.
Ngakho konke usizo lwe-amino acid, ukuthatha izithako zokudla ngokufakwa kwayo kunokuphikisana okucacile kakhulu:
- umfutho wegazi ophakeme: ukweqisa kwe-AA kuholela ekwandeni okwengeziwe komfutho wegazi;
- i-schizophrenia: i-AK ithinta i-NS, izimpawu zesifo ziba zimbi;
- izinkinga zengqondo: ukweqisa izidakamizwa kwe-AK kuholela ekungalinganisweni kokuhlanganiswa kwama-neurotransmitters;
- ukuxhumana nezinye izidakamizwa: i-phenylalanine ikhombisa umthelela kuma-antipsychotic kanye nezidakamizwa ze-hypertension;
- imiphumela engemihle (isicanucanu, ikhanda elibuhlungu, ukubhebhetheka kwesisu): izimo zidalwa yimiphumela yezithako zokudla.
Ukusetshenziswa kwe-phenylalanine ngabesifazane abakhulelwe akunakwenzeka uma kungekho nkomba eqondile yalokhu. Uma kungekho ukuphazamiseka komzimba okutholakele, ukungena kwe-AA emithonjeni yangaphandle kwanele ukusebenza okujwayelekile komzimba.
Sibutsetelo sezithako zokudla ezine-phenylalanine
| Igama elengeziwe | Ifomu lokukhishwa | intengo, hlikihla. |
| Okuhamba phambili Kwezokwelapha, i-D-Phenylalanine | 500 mg, amaphilisi angama-60 | 1000-1800 |
| Umthombo Naturals, L-Phenylalanine | 500 mg, amaphilisi ayi-100 | 600-900 |
| MANJE, L-Phenylalanine | 500 mg, amaphilisi ayi-120 | 1100-1300 |
Isiphetho: Kungani Ibhalansi yePhenylalanine Ibalulekile
Ngakho-ke, i-phenylalanine ayinakuguqulwa, njengoba kufakazelwa izifundo zelebhu. It ubamba iqhaza eziningana izinqubo eziyisisekelo umzimba. Ngakho-ke, kufanele uhlale udla ukudla kwakho kwansuku zonke.
Kufanele uthathe nini imithamo eyengeziwe ye-AK ngendlela yezithako zokudla? Impendulo ilula. Uma kunesidingo sangempela salokhu, kuqinisekiswa ukuhlolwa kwezokwelapha. Kwezinye izimo, kunconywa kakhulu ukuthi weqe umthamo wansuku zonke (ojwayelekile)!
