Umahluko phakathi kwe-cystine kunye ne-cysteine

Intshayelelo

Emhlabeni Kwimichiza kunye nebhayoloji, kuqhelekile ukufumana amagama afanayo kwaye anokubangela ukudideka, njenge-cystine kunye ne-cysteine. Nangona babelana ngeempawu ezithile, ziimolekyuli ezahlukeneyo ezinemisebenzi ethile kwizinto eziphilayo.

Yintoni i-cystine?

I-Cystine yi-amino acid ene-oxidized eyenziwe kwiimolekyuli ezimbini ze-cysteine, i-amino acid enesulfure. Ngoko ke, i-molecule eyenziwe ngama-cysteines amabini adityaniswe yi-disulfide bond.

Imisebenzi ye-cystine

• Ikhusela ubume beeprotheni ngokwenza iibhulorho ze-disulfide kumatyathanga e-polypeptide.
• Igalelo ekubunjweni kweenwele eziphilileyo, ulusu kunye nezikhonkwane.
• Inceda ukugcina amanqanaba e-glutathione, i-antioxidant ekhusela iiseli kumonakalo we-oxidative.

Yintoni i-cysteine?

I-Cysteine ​​​​yisulfure equlethe i-amino acid ebalulekileyo kwaye yenye yeebhloko zokwakha iiprotheni. Kubaluleke kakhulu ekusebenzeni okufanelekileyo kwe-immune system, imveliso ye-antioxidants kunye ne-fat metabolism.

Imisebenzi ye-cysteine

• Ithatha inxaxheba kwimveliso ye-glutathione, enye yezona zinto zibalulekileyo ze-antioxidants kwiiseli.
• Ivuselela iprotein synthesis kunye nokuthuthwa kwesinyithi esinzima ngaphandle komzimba.
• Ukuphucula ukufunxwa kwezondlo eziphuma emathunjini.
• Ukubonelela umzimba ngesulfure efunekayo ekuveliseni i-keratin, inxalenye yesakhiwo sesikhumba, iinwele kunye nezipikili.

Umahluko phakathi kwe-cystine kunye ne-cysteine

Umahluko omkhulu phakathi kwe-cystine kunye ne-cysteine ​​​​yokuba i-cystine yimolekyuli ene-oxidized eyenziwe ngeeamolekyuli ezimbini ze-cysteine, ngelixa i-cysteine ​​​​yi-amino acid ebalulekileyo equlethe isulfure.

Omnye umehluko obalulekileyo kukuba i-cystine izinzile ngakumbi kune-cysteine ​​​​ngenxa yesakhiwo sebhulorho ye-disulfide, eyikhusela kwi-oxidation kunye nokubola.

I-cystine inendima ephambili yolwakhiwo kwiiprotheni, ngelixa i-cysteine ​​​​inendima ebanzi kwimetabolism yomzimba kunye nempilo iyonke.

Isiphelo

I-cystine kunye ne-cysteine ​​​​ziimolekyuli ezahlukeneyo ezinemisebenzi ethile kwizinto eziphilayo. I-Cystine yi-molecule ene-oxidized eyenziwe yimanyano ye-cysteines ezimbini kwaye inomsebenzi obalulekileyo wesakhiwo kwiiprotheni. I-cysteine, kwelinye icala, i-amino acid ebalulekileyo edlala indima ebalulekileyo kwimetabolism yomzimba kunye nempilo yonke.

Kubalulekile ukuqonda umahluko phakathi kwezi molekyuli zimbini ukuze uzisebenzise ngokufanelekileyo kwiinkqubo zebhayoloji kunye neekhemikhali, kunye nokuqonda indlela ezisebenza ngayo emzimbeni ukugcina umzimba ophilileyo. imeko entle de salud en general.
