Yintoni iPhenylalanine, yenza ntoni? Ifumaneka Kokuphi Ukutya?

Yintoni phenylalanine? Nangona eli gama lisikhumbuza igama lesongezelelo sesondlo, ngokwenene i-amino acid eveliswa emzimbeni wethu. Kukho kwakhona izongezo zesondlo. Ukutya ukutya okuthile kunceda ukuvelisa le amino acid.

Phenylalanine, I-amino acid efunyenwe kukutya okuninzi kwaye isetyenziswe yimizimba yethu ukuvelisa iiprotheni kunye nezinye iiamolekyu ezibalulekileyo. Iziphumo zayo kuxinzelelo, iintlungu kunye nokuphazamiseka kwesikhumba ziye zaphandwa. Kubalulekile ukuhlanganiswa kwamahomoni athile kunye ne-neurotransmitters edlala indima ekulawuleni isimo sengqondo kunye nobunzima bomzimba.

Yintoni iPhenylalanine?

Kukwi-amino acid, eyibhloko yokwakha iiproteni emizimbeni yethu. Le molekyuli ikhona ngeendlela ezimbini: L-phenylalanine kunye ne-D-phenylalanine. Ziphantse zafana kodwa zinesakhiwo semolekyuli esahluke kancinane. Ifom ye-L ifumaneka ekutyeni kwaye isetyenziselwa ukuvelisa iiprotheyini emizimbeni yethu, ngelixa i-D-form idityaniswe ukuze isetyenziswe kwezinye izicelo zonyango.

Umzimba wethu awukwazi ukuvelisa i-L-phenylalanine eyaneleyo ngokwawo. Ngoko ke, yi-amino acid ebalulekileyo ekufuneka ifunyenwe ekutyeni. Ifumaneka kwiintlobo ngeentlobo zokutya, ukusuka kwizityalo nakwimithombo yezilwanyana.

Ukongeza kwindima yayo kwimveliso yeprotheyini, i-phenylalanine iphinda isetyenziswe ukwenza ezinye iimolekyuli ezibalulekileyo emizimbeni yethu. Ezinye zezi zithumela imiqondiso phakathi kwamalungu ahlukeneyo omzimba wethu.

I-Phenylalanine ifundwe njengonyango kwiimeko zonyango ezahlukeneyo, kubandakanya izifo zesikhumba, ukudakumba, kunye neentlungu. Nangona kunjalo, ukuphazamiseka kwemfuza phenylketonuria (PKU) Kuyingozi kubantu abane

Yintoni eyenza iPhenylalanine?

umzimba wethu protein Ifuna ii-amino acids ukuyenza. Iiprotheyini ezininzi ezibalulekileyo zifumaneka kwingqondo, igazi, izihlunu, amalungu angaphakathi kwaye phantse yonke indawo emzimbeni wethu. IPhenylalanine ibalulekile ekuveliseni ezinye iimolekyuli ezifana nezi:

• Tyrosine: Phenylalanine tyrosine iveliswa. Isetyenziselwa ukwenza iiprotheni ezintsha okanye ukuziguqulela kwezinye iimolekyuli.

• Epinephrine kunye norepinephrine: Xa sidibana noxinzelelo, ezi molekyuli zibalulekile kwimpendulo yomzimba "yokulwa okanye yokubhabha".

• I-Dopamine: Le molekyuli ibumba iinkumbulo nobuchule bokufunda, kunye neemvakalelo zolonwabo kwinkumbulo.

Iinzuzo zePhenylalanine

Uphononongo lwezenzululwazi lujolise kwiinzuzo zezongezo ze-phenylalanine. Ngokweziphumo zezifundo, izibonelelo ze-phenylalanine zimi ngolu hlobo lulandelayo;

• Isetyenziselwa ukuvelisa ezinye iikhompawundi

Njengezinye ii-amino acids, i-phenylalanine idlala indima ebalulekileyo ekuveliseni ezinye iikhompawundi ezibalulekileyo ezibalulekileyo empilweni. Ngokomzekelo, isetyenziselwa ukuvelisa i-dopamine, i-neurotransmitter ebandakanyekayo ekufundeni, imemori kunye neemvakalelo.

Umzimba uphinde uguqule i-phenylalanine ibe yi-tyrosine, i-amino acid enceda ukudibanisa iiprotheni. Ikwadlala indima ekuveliseni i-norepinephrine kunye ne-epinephrine, i-neurotransmitters ekhutshwe ngumzimba ekuphenduleni kwiimeko ezixinzelelekileyo.

Xa kukho ukunqongophala kule amino acid ibalulekileyo, uluhlu olude lweengxaki luvela, kuquka inkungu yengqondo, ukudakumba, ukulahlekelwa yinkumbulo kunye nokudinwa.

• kuphelisa ukudandatheka

Enye yeenzuzo eziphambili ze-L-phenylalanine kukukwazi ukuphucula isimo sengqondo kunye nokukhusela kuxinzelelo. Olunye uphononongo lufumene iziphumo ezinamandla zokuba iphucula ngokufanelekileyo imo.

• Ikhusela isifo sikaParkinson

Isifo sikaParkinson sichaphazela inkqubo ye-nervous central, ebangela iimpawu ezifana nokungcangcazela. Ngokutsho kophando, Isifo sika-Parkinson siphumela ekuphelelweni kwe-tyrosine, i-dopamine, kunye ne-norepinephrine, yonke into eyenziwa kwi-phenylalanine.

• Iphelisa iintlungu ezingapheliyo

Olunye uphando luye lwafumanisa ukuba i-phenylalanine yintlungu yendalo enciphisa intlungu engapheliyo.

• Ixhasa ukubhitya

Izifundo kunye ne-L-phenylalanine zifumene ukunciphisa ubungakanani besinqe. Ngenxa yokuba amanqanaba e-cholecystokinin (CCK), ihomoni enceda ukugcina ukutya phantsi kolawulo, iye yanda. 

• Inceda ukuphelisa utywala

Uphando lubonise ukuba le amino acid, kunye nezinye i-amino acids, inokunceda ukukhulula iimpawu zokuyeka utywala.

Iingozi zePhenylalanine 

Iphenylalanine ifumaneka kukutya okuninzi okuneprotheyini. Kuxelwe "njengokhuseleko ngokubanzi" yi-Food and Drug Administration (FDA). Esi sixa se-phenylalanine esifumaneka ekutyeni asibeki mngcipheko kubantu abasempilweni. Nangona kunjalo, abafazi abakhulelweyo kufuneka bakuphephe ukuthatha izongezo ze-phenylalanine.

Kukho ngaphandle okuphawulekayo kule amino acid. Abantu abane-amino acid metabolism disorder, oko kukuthi, phenylketonuria (PKU), abanakukwazi ukucubungula ngokufanelekileyo le amino acid. egazini i-phenylalanine concentrations ngamaxesha angama-400 aphezulu kunalawo angenayo i-PKU. Oku kugxila kuphezulu ngokuyingozi kunokubangela ukonakala kwengqondo kunye nokukhubazeka kwengqondo, kunye nengxaki yokuhambisa ezinye ii-amino acids ebuchotsheni.

Ngenxa yobuzaza be-phenylketonuria, iintsana zihlala zivavanyelwa i-PKU kamsinya nje emva kokuzalwa. Abantu abane-PKU badla ngokutya okukhethekileyo okuneprotheyini ephantsi egcinwa ubomi bonke.

Kokukuphi ukutya efumaneka kwiPhenylalanine?

I-Phenylalanine yenzeka ngokwemvelo kwimithombo yokutya equlethe zombini iprotheni yezityalo kunye nezilwanyana. Inyama, intlanzi kunye neenkukhu, amaqanda, amandongomane, imbewu kunye neemveliso zesoya zezinye zokutya okutyebileyo kwiphenylalanine.

I-Phenylalanine ifumaneka njengesongezo sokutya kwintlaka, isoda, kunye nezinye iimveliso zokutya. I-Aspartame sisimuncu-muncu sokwenziwa esenziwe yi-aspartic acid kunye ne-phenylalanine. Nangona ivunyiwe ukuba isetyenziswe yi-FDA, kukho imibuzo enzulu malunga nokhuseleko lwayo.

I-Phenylalanine supplements ziyafumaneka kwabo bafuna ukwandisa i-dopamine ngezongezo. Ezi zongezelelo zidla ngokufumaneka kwifom yomgubo okanye i-capsule. Ineendlela ezahlukeneyo zokusetyenziswa kodwa ngokuyintloko isetyenziselwa ukukhulisa imo kunye nobukrelekrele bengqondo.
