I-L-Methionine, i-amino acid ebalulekileyo, ibisoloko iphambili kwiingxoxo ezahlukeneyo zesayensi kunye nezoshishino. Le khemikhali imangalisayo ayibalulekanga nje kuphela kwiinkqubo zebhayoloji ezisisiseko kodwa ikwasetyenziswa kwiindawo ezininzi, ukusuka kwimpilo nesondlo ukuya kwezolimo nakwezinye iindawo.

Ukubaluleka kwiinkqubo zebhayoloji

I-L-Methionine idlala indima ebalulekileyo emzimbeni womntu. Sisitena esibalulekileyo sokwakha iiproteni, njengoko iyi-amino acid yokuqala ekuhlanganiseni iiproteni ezintsha ngaphakathi kweeseli. Emva kokuzilolonga, umzekelo, iqala ukuveliswa kweeproteni ezintsha kwimisipha ukuze kulungiswe umonakalo. Ukongeza, inegalelo kwinkqubo yomzimba yokulwa ne-antioxidant. I-Glutathione, enye yezona antioxidants zinamandla emzimbeni, yenziwe kwi-L-Methionine. Le antioxidant inceda ekunciphiseni ii-reactive oxygen species (ROS), iimolekyuli eziyingozi ezenziwe ngexesha leenkqubo zeseli eziqhelekileyo ezifana nokutya, ukulala, nokuphefumla. Ngokwenza njalo, ikhusela iiseli kwi-oxidative stress, enokukhokelela kwiingxaki ezininzi zempilo kubandakanya iintloko ezibuhlungu, izifo zentliziyo nezesibindi, umhlaza, kunye nokwaluphala kwangethuba.

Ngaphezu koko, i-L-Methionine ifundwe ngendima yayo ekulawuleni umsebenzi we-DNA. Inkqubo ye-methylation, ebalulekileyo ekulawuleni ukuba zeziphi iijini ezisebenzayo kwi-DNA yethu, ixhomekeke kule amino acid. Ukuphazamiseka kwiinkqubo ze-methylation ye-DNA ezidibeneyo, ezixhomekeke kwi-L-Methionine, kunokukhokelela kwiingxaki zempilo ezinzulu ezifana nezifo ze-metabolic, ukudakumba, umhlaza, kunye nenkqubo yokwaluphala.

Izicelo kwiCandelo lezeMpilo nelezonyango

Kwicandelo lezonyango, i-L-Methionine ibonakalise ithemba kwiindawo ezininzi. Ithathwa njengonyango lokugqithisa i-acetaminophen. Ukuthathwa kwe-L-Methionine ngomlomo kwiiyure ezili-10 emva kokugqithisa i-acetaminophen kunokuthintela iimveliso zeyeza ekonakaliseni isibindi. Nangona kunjalo, kufuneka kuqatshelwe ukuba kukho ezinye iindlela zonyango, kwaye ukusebenza kwayo kule nkalo kusajongwa.

Kukwakho nomdla okhulayo kwikhono layo lokunciphisa umngcipheko weentlobo ezithile zomhlaza. Ezinye izifundo zelebhu zibonise ukuba i-L-Methionine inokuphazamisa umjikelo wokukhula kweeseli kwiiseli zomhlaza webele, i-pancreatic, kunye ne-biver, nto leyo ekhokelela ekufeni kweeseli. Kodwa iziphumo ezivela kwizifundo ezahlukeneyo ziyaphikisana, ezinye zibonisa ukuba ukunciphisa i-L-Methionine kunokunciphisa umngcipheko womhlaza. Kufuneka uvavanyo oluninzi ebantwini ukuze kufikelelwe kwisigqibo esicacileyo ngendima yayo ekuthinteleni umhlaza.

Ngaphezu koko, i-L-Methionine inokunceda ekuthinteleni iziphene zokuzalwa kwityhubhu ye-neural. Ityhubhu ye-neural, ekhula iye kwingqondo yomntwana, entloko, emgogodleni, nakwithambo lomqolo kwisigaba sokuqala sokukhulelwa, ngamanye amaxesha ayivaleki kakuhle, nto leyo ebangela iziphene ezifana ne-spina bifida, i-anencephaly, kunye ne-encephalocele. Ubungqina obuthile, nangona busafuna uphando olongezelelekileyo, bubonisa ukuba ukutya i-L-Methionine eninzi ekutyeni kunokunciphisa amathuba okuba neziphene ezinjalo zokuzalwa.

Ukwandisa Amathuba Kwamanye Amashishini

Kwishishini lokutya, i-L-Methionine isebenza njengesongezelelo esibalulekileyo sesondlo. Njenge-amino acid ebalulekileyo umzimba womntu ongenakuyivelisa wodwa, yongezwa kwiimveliso ezahlukeneyo zokutya ukuze kuphuculwe ixabiso lazo lesondlo. Ikwabandakanyeka kwimpendulo yeMaillard, isabela ngokunciphisa iiswekile ukuze kuvele iincasa kunye namavumba afanelekileyo, ngaloo ndlela iphucula incasa yokutya okucutshungulwayo okufana nesonka, iinkozo, kunye neemveliso zenyama.

Ishishini lokutya likwaqaphele ukubaluleka kwe-L-Methionine. Ukuyifaka kwimfuyo nakwiinkukhu kuphucula umgangatho weprotheyini yokutya. Oku, kukhuthaza ukukhula nophuhliso lwezilwanyana, kwandisa imveliso yenyama, amazinga okubeka amaqanda kwiinkukhu, kunye nokuveliswa kobisi kwiinkomo zobisi. Kwizolimo zasemanzini, kuphucula ukutyeba kokutya kweentlanzi nee-shrimp, kwandisa amasosha omzimba wazo, kwaye kuphucula amazinga okusinda kunye nesivuno.

Njengoko uphando kwi-L-Methionine luqhubeka lusanda, le amino acid ibalulekileyo inokuba nendima ebaluleke ngakumbi ekuphuculeni impilo yabantu, ukuphucula umgangatho wokutya nokutya, kunye negalelo kwiinkqubo zoshishino ezizinzileyo kwixesha elizayo.
