Ingahlukaniswa kanjani i-peptide emihlanu neyisithupha?
Ama-peptide amahlanu: abhekisela ekushukumiseni umzimba ukuba ukhiqize impendulo engaqondile yokuzivikela komzimba, amasosha omzimba kanye nemikhiqizo yokusabela kokuzivikela komzimba kanye nokuzwela kwe-lymphocyte ukuze kuhlanganiswe, umphumela wokuzivikela komzimba (okucacile) wezinto ezibonakalayo.I-Hexapeptide: Ukulandelana kwama-amino acid axhunywe yi-amide bond, ehlanganisa ama-amin ayisithupha...Funda kabanzi -
Uyini umumo wama-peptide enziwe ngokwezifiso?Lawa maphuzu uyawazi?
I-Peptide chain synthesis isetshenziswe kabanzi emikhakheni eminingi, ikakhulukazi ekuthuthukisweni kwezidakamizwa, ucwaningo lwebhayoloji kanye ne-biotechnology.Ama-peptide anobude obuhlukahlukene nokulandelana kwawo angahlanganiswa ngokusebenzisa i-peptide chain synthesis yokulungiswa kwezidakamizwa, umthwali wezidakamizwa, ukuhlaziya amaprotheni, ucwaningo olusebenzayo...Funda kabanzi -
Ukuhlaziywa kwezindlela zokuhlanganisa ezifana ne-peptide
Ubuchwepheshe bokuhlanganisa obufana ne-peptide Ucwaningo nokuthuthukiswa kwemithi ye-peptide lukhula ngokushesha kwezokwelapha.Kodwa-ke, ukuthuthukiswa kwezidakamizwa ze-peptide kunqunyelwe izici zabo siqu.Isibonelo, ngenxa yokuzwela okukhethekile kwe-enzymatic hydrolysis, ukuzinza kuyancipha, futhi ...Funda kabanzi -
Isingeniso esifushane se-tidulutide
Indlela yokusebenza ye-tidulutide Gattex (teduglutide) I-Teduglutide iyi-analogue yomuntu yemvelo ye-glucagon-like peptide-2 (GLP-2), i-peptide efihliwe ngamaseli e-L ku-distal gut.I-GLP-2 yaziwa ngokuthuthukisa ukugeleza kwegazi emathunjini kanye ne-portal futhi ivimbele ukukhishwa kwe-asidi esiswini.Okweziqu ze-lu pept...Funda kabanzi -
Umehluko phakathi kwamaketanga e-peptide namaketanga e-peptide
Umehluko phakathi kwama-peptide namaketango e-peptide yile: 1.imvelo ehlukile.2.Izici ezihlukene.3.inani lama-amino acid ahlukene.Yakhiwa ama-amino acid amathathu noma ngaphezulu i-peptide yamangqamuzana i-polypeptide, isisindo sayo samangqamuzana angaphansi kwe-10000 Da, ingadlula endaweni engenakunyakaziswa ...Funda kabanzi -
Ukuguqulwa kwe-methylation
I-Methylation-modified peptides, eyaziwa nangokuthi i-methylation-recognized peptides, ayimihlobiso yangemuva kokuhumusha yamaprotheni (PTMs) futhi idlala indima ebalulekile yokulawula cishe yonke imisebenzi yempilo kumaseli.Amaprotheni acutshungulwa yi-methyltransferase ukuze adlulisele amaqembu e-hydroxyl ezindaweni ezithile ze-amino acid...Funda kabanzi -
Leli phepha lichaza kafushane i-mezlocillin kanye nokusebenza kwayo
I-Mezlocillin ine-spectrum ye-antibacterial efanayo ne-piperacillin, inomsebenzi ongcono wokulwa namagciwane ngokumelene namagciwane e-Enterobacteriaceae, futhi ayisebenzi kahle ngokumelene ne-Pseudomonas aeruginosa kune-azlocillin.Isetshenziswa ekwelapheni ukutheleleka komgudu wokuphefumula kanye nokutheleleka komgudu womchamo okubangelwa ...Funda kabanzi -
