Iipeptides zizinto ezisisiseko ezenziwe ngazo zonke iiseli emzimbeni womntu.Izinto ezisebenzayo zomzimba womntu zikwimo yeepeptides, ezithatha inxaxheba eziyimfuneko ukuze umzimba ugqibezele imisebenzi eyahlukeneyo enzima yefiziyoloji.

Iipeptides zihlala zikhankanywa kwinkulungwane yama-21, uthotho lweepeptides njengokutya okusebenzayo okutsha, okuthandwa kakhulu ngabantu.Ukuza kuthi ga ngoku, kukho amazwe angaphezu kwama-30 aqhuba uphando lwenzululwazi ye-peptide kunye nokusetyenziswa kwesondlo somntu emhlabeni.Phakathi kwazo, iJapan, iFransi, iUnited States, iSouth Korea, iTaiwan, iHongkong kunye neminye imimandla enemiqondo ephambili ithengise iimveliso zepeptide.Ngombono oqinileyo wempilo yentlalo kule minyaka yakutsha nje, abantu bebesazi ngokubaluleka kweepeptides, ke ithemba lokuthengisa lokutya okunesondlo okunempilo kunye neepeptides njengesiseko eTshayina linethemba elikhulu.

Yintoni i-peptide?

I-Peptide luhlobo lwe-biochemical substance phakathi kwe-amino acid kunye neprotheni, ubunzima bayo bemolekyuli buncinci kuneprotheni, kodwa inkulu kune-amino acid, ngoko ke yinxalenye yeprotheni.Ii-amino acids ezimbini nangaphezulu zidityaniswe ngamabhondi e-peptide, kwaye “ikhonkco le-amino acid” okanye “umtya we-amino acid” owenziweyo ubizwa ngokuba yipeptide.Phakathi kwazo, iipeptides ezenziwe ngaphezu kwe-10 amino acid zibizwa ngokuba yi-polypeptides, kwaye ezo zenziwe nge-2 ukuya kwi-9 amino acids zibizwa ngokuba yi-oligopeptides, kwaye ezo zenziwe nge-2 ukuya kwi-4 amino acids zibizwa ngokuba yi-peptides encinci.

I-Peptide ingcono kuneprotheyini ephezulu.Yenziwe nge-amino acid, kodwa ingcono kune-amino acids.Iiprotheyini ezifakwe ngabantu zifunxwa kakhulu ngohlobo lweepeptides emva kokusebenza kwee-enzymes kwindlela yokugaya.

1.Ukwandisa ukukhuseleka komntu

I-peptide esebenzayo ine-amino acids eyandisa i-immunity, apho abameli be-arginine kunye ne-glutamate.I-Arginine inokuphucula ukusebenza kwe-immune ye-macrophages kwiiseli zokuzivikela, ngelixa ihlasela iintsholongwane ezihlaselayo emzimbeni.Intoni'Ngaphezu koko, i-glutamate ivelisa iiseli zokuzivikela ezilwa inani elikhulu leentsholongwane xa zihlasela umzimba.Ngoko ke, i-peptides esebenzayo inokuphucula ukugonywa kweeseli kunye nokukhuthaza ukwanda kwe-T lymphocytes, ukuphucula umsebenzi we-macrophages kunye nokuphucula umsebenzi weeseli ze-NK.Izifundo ziye zaxela ukuba i-peptide esebenzayo inokukhuthaza ukuveliswa kwe-tumor necrosis factor.Ukuba uziva ungakhululekanga, ukutya i-peptide esebenzayo kuya kudlala ngokukhawuleza umphumo wokuzivikela.

2.Iipeptides zinokunciphisa ubunzima kwaye zinciphise amafutha-ngokwezonyango okubizwa ngokuba kukuncitshiswa kwamafutha

(1)Khuthaza ukutshiswa kwamafutha, kwaye ujike ube namandla adingwa ngumzimba.

(2)Zonke iiseli emzimbeni zine-hormone receptor, xa iipeptides ziqhagamshelwe kwi-receptor yeeseli ezinamafutha, uthotho lwe-enzyme reaction yenzeke, ibangele ukuba amanqatha aguqulwe, ebizwa ngokuba yi-lipolysis.

(3) Iipeptide zinefuthe elichasayo kwi-insulin.I-insulin inokukhuthaza ukufunxwa kwamafutha, iswekile kunye ne-amino acids ngeeseli ezibizwa ngokuba yi-fat synthesis.Umphumo we-HGH uchasene nayo, ngoko unokuthintela ukuqokelela kwamafutha emzimbeni.I-HGH iyaziwa ngokuiiyeza elisebenzayo lelahleko lobunzimanjengoi-protagonist yeenkqubo ezahlukeneyo zokunciphisa umzimba.Uninzi lwamafutha ancitshiswe ziipeptides akwisisu, iimpundu kunye necala elingaphakathi leengalo ezingaphezulu.. Ngoko ke, i-peptide kuphela kwendlela elula yokunciphisa umzimba engafuni ukuba isigulane sibale iikhalori okanye sinikele ingqalelo kuhlobo lokutya.

3.Susa imibimbi kwaye uhlaziye iinwele

I-Peptides inokukhuthaza ukuhlanganiswa kwe-collagen kunye nezinye iiprotheni, ngoko inokulusulela ulusu kwaye isuse imibimbi.Intoni's ngakumbi, i-peptide inokukhuthaza ukukhula kweenwele, kwaye yenza umgangatho weenwele zayo ube ngcono.

4.Ukuthintela isifo senhliziyo kunye ne-stroke, ukunciphisa uxinzelelo lwegazi

I-cholesterol ephezulu kunye noxinzelelo lwegazi ngunobangela wesifo sentliziyo kunye ne-stroke.ICholesterol yahlulahlulwe yaba yiHDL kunye neLDL.Iipeptide zinokunciphisa i-LDL, kwaye zandise iHDL, kunye nokunciphisa uxinzelelo lwegazi.Kwixesha elidlulileyo, i-atherosclerosis yayicatshangelwa ukuba ibangelwa yi-cholesterol clot eqhotyoshelwe kwisitya segazi, nangona kunjalo, ingcamango entsha yakutshanje ikholelwa ukuba i-atherosclerosis ngokwenene sisifo se-metabolic.Ilungu eliphambili elingundoqo sisibindi.Indima yesibindi kukuguqula i-cholesterol ibe yi-bile acids, idlule kwi-bile duct kunye ne-gallbladder, emva koko idlule emathunjini.Umsebenzi wepeptide kukwandisa inani le-LDL receptors kwiiseli zesibindi.Ngoko ke, le metabolism inokuphuculwa, kwaye i-LDL iguqulwa ibe yinyongo, ekhutshwe egazini.
