I-peptide ye-molecule encane yakhiwe ngama-amino acid angu-2 ~ 9, futhi isisindo sayo se-molecule singaphansi kwe-1000 Da, inemisebenzi ehlukahlukene ye-physiological kanye nenani eliphezulu lezakhi.

Umehluko phakathi kwe-molecule encane ye-peptide namaprotheni

1.Ukumuncwa okulula futhi akukho antigenicity.

2.Umsebenzi oqinile webhayoloji kanye nomsebenzi obanzi.

3.Isakhiwo se-peptide ye-molecule encane kulula ukusishintsha futhi sihlanganise kabusha.

4.I-peptide ye-molecule encane ngeke ibangele ukondleka ngokweqile.

Umehluko phakathi kwe-molecule encane ye-peptide ne-amino acid

1.Ukumuncwa kanye nemetabolism ye-peptide ye-molecule encane kuyashesha kune-amino acid yamahhala, futhi amathuba okusebenzisa i-molecule encane ye-peptide ukuze kuhlanganiswe amaprotheni emzimbeni womuntu aphezulu ngo-25% kunokusetshenziswa kwe-amino acid.

2.Kunomehluko ngokuphelele phakathi kwendlela yokumunca ye-molecule encane ye-peptide ne-amino acid.I-peptide ye-molecule encane inezici zejubane eliphezulu lokugijima, ukusetshenziswa kwamandla okuphansi, ukungaqhudelana kanye nokuvinjelwa.

3.Kunezinhlobo ezingama-20 kuphela zama-amino acid ezingamuncwa futhi zisetshenziswe umzimba womuntu, nokho, ama-amino acid anezinhlobo ezahlukene nezinombolo ezihlukene angakha izinkulungwane ze-molecule encane ye-peptide ngokuvumela nokuhlanganiswa.

I-4.I-peptide ye-molecule encane inomsebenzi oyingqayizivele wokuphila, ingabandakanyeka ngokuqondile ekusetshenzisweni kwamangqamuzana egazi, ubuchopho, amangqamuzana ezinzwa, amangqamuzana emisipha, amangqamuzana egciwane, amangqamuzana e-endocrine kanye nesikhumba, yini'Ngaphezu kwalokho, ingabamba iqhaza emisebenzini ehlukahlukene yokuphila komzimba.

1. I-peptide ye-molecule encane inesakhiwo esilula nesisindo se-molecule encane, engadlula ngokushesha ekumunceni kwe-mucosal yamathumbu ngaphandle kokugaya noma ukusetshenziswa kwamandla.Ngakho-ke, ukumuncwa, ukuguqula kanye nokusetshenziswa kwe-molecule encane ye-peptide esebenzayo kusebenza kahle kakhulu.

2. Iqiniso lokuthi i-molecule encane yama-peptide asebenzayo ingangena ngokuqondile kumaseli kuwukubonakaliswa okubalulekile komsebenzi wawo wezinto eziphilayo.Ama-peptide ama-molecule amancane angangena ngokuqondile kumaseli ngokusebenzisa umgoqo wesikhumba, umgoqo wegazi nobuchopho, umgoqo we-placental, kanye nomgoqo we-mucosal wamathumbu.

3. Ama-peptide ama-molecule amancane anemisebenzi ebalulekile ye-physiological, ehlanganisa umzimba womuntu'amahomoni, izinzwa, ukukhula kwamaseli kanye nokuzala.Ingalawula imisebenzi yezemvelo yezinhlelo namaseli ahlukahlukene emzimbeni, futhi igcine umzimba womuntu'umsebenzi ojwayelekile wokuphila wemizwa, ukugaya, ukuzala, ukukhula, ukuvivinya umzimba, imetabolism, njll.

4. I-peptide ye-molecule encane ayinawo nje kuphela izakhi ezidingekayo ekukhuleni nasekuthuthukisweni komuntu, kodwa futhi inomsebenzi othize wezinto eziphilayo, ongavimbela futhi welaphe i-thrombosis, ukukhuluphala ngokweqile, umfutho wegazi ophakeme, ukubambezeleka ukuguga, ukulwa nokukhathala, futhi kuthuthukise amasosha omzimba. .
