Iyini indima ye-phosphorylation kuma-peptides?
I-phosphorylation ithinta zonke izici zokuphila kwamaselula, futhi amaprotheni kinases athinta zonke izici zemisebenzi yokuxhumana ye-intracellular ngokulawula izindlela zokubonisa izimpawu kanye nezinqubo zamaselula.Nokho, i-phosphorylation engafanele futhi iyimbangela yezifo eziningi;ikakhulukazi, amaprotheni kinas ashintshiwe...Funda kabanzi -
Ucwaningo oluningana nobuchwepheshe bokukhiqiza kwama-peptide asebenzayo
Indlela yokukhipha Ngeminyaka yawo-1950 kanye nawo-1960, amazwe amaningi emhlabeni, kuhlanganise neShayina, ayekhipha ama-peptide ezithweni zezilwane.Isibonelo, umjovo we-thymosin ulungiswa ngokuhlaba ithole elisanda kuzalwa, ukususa i-thymus yalo, bese usebenzisa i-biotechnology yokwehlukanisa oscillating ukuhlukanisa...Funda kabanzi -
Chaza kafushane i-glycine ne-alanine
Kuleli phepha, kwethulwa ama-amino acid amabili ayisisekelo, i-glycine (Gly) ne-alanine (Ala).Lokhu kungenxa yokuthi bangasebenza njengama-amino acid ayisisekelo futhi ukwengeza amaqembu kuwo kungakhiqiza ezinye izinhlobo zama-amino acid.I-Glycine inokunambitheka okumnandi okukhethekile, ngakho-ke igama layo lesiNgisi livela kwelesiGreek glykys(swee...Funda kabanzi -
Umhloli wezinto eziphilayo wakwaGutuo ukufundise ukuthi ungasebenzisa kanjani i-chromatograph ewuketshezi
I-Liquid chromatograph iyichromatograph ehlakaniphile egxile kumsebenzisi, enokusebenza okuyisisekelo kwe-HPLC evamile, futhi inweba imisebenzi ehlakaniphe kakhulu.Ingakwazi ukuhlangabezana nezidingo ezahlukene zohlelo lwabasebenzisi, ukuze abasebenzisi bakwazi ukuyisebenzisa kalula futhi bathole idatha yokuhlaziya enembile...Funda kabanzi -

Ingabe i-trifluoroacetyl tripeptide-2 ibambezela ukuguga?
Mayelana nathi: I-peptide iwuchungechunge lwama-amino acid axhunywe amabhondi e-peptide.Ama-peptide ahileleke kakhulu ekulawuleni amaprotheni, i-angiogenesis, ukwanda kwamaseli, i-melanogenesis, ukufuduka kwamangqamuzana, nokuvuvukala.Ama-peptide e-Bioactive asetshenziswe kabanzi embonini yezimonyo emashumini eminyaka amuva nje.I-Peptid...Funda kabanzi -
Inkinga yamabhondi e-disulfide ngaphakathi kwama-peptides
Amabhondi e-disulfide ayingxenye ebalulekile yesakhiwo esinezinhlangothi ezintathu samaprotheni amaningi.Lezi zibopho eziqinile zingatholakala cishe kuwo wonke ama-peptide angaphandle kwamaseli nama-molecule wamaprotheni.Isibopho se-disulfide senziwa lapho i-athomu yesulfure ye-cysteine yakha isibopho esisodwa esihlangene nenye ingxenye ye-t...Funda kabanzi -
isigqoko okudingeka ukwazi nge-arginine?
I-Arginine i-α-amino acid eyingxenye ye-protein synthesis.I-Arginine ihlanganiswa imizimba yethu futhi siyithola enyameni, amaqanda nemikhiqizo yobisi kanye nemithombo ethile yezitshalo.Njenge-ejenti yangaphandle, i-arginine inemiphumela eminingi yokunakekelwa kwesikhumba.Nazi ezinye zezinzuzo eziyinhloko ze-arginine ...Funda kabanzi -
Indlela yokwenziwa kwe-L-isoleucine
I-L-isoleucine ingenye yama-amino acid ayisishiyagalombili abalulekile emzimbeni womuntu.Kubalulekile ukwengeza ukukhula okuvamile kosana kanye nebhalansi ye-nitrogen yomuntu omdala.Kungakhuthaza ukwakheka kwamaprotheni, kwandise i-hormone yokukhula namazinga e-insulin, kugcine ibhalansi yomzimba, futhi kwandise ...Funda kabanzi -
Isikimu sokuklama nesisombululo seketango le-polypeptide peptide
I. Isifinyezo Ama-Peptides ama-macromolecules akhethekile kangangokuthi ukulandelana kwawo akujwayelekile kumakhemikhali awo kanye nezici zomzimba.Amanye ama-peptide anzima ukuwahlanganisa, kuyilapho amanye kulula ukuwahlanganisa kodwa kunzima ukuwahlanza.Inkinga engokoqobo ukuthi ama-peptides amaningi athe ...Funda kabanzi -
Ingabe i-palmitoyl tetrapeptide-7 ingawulungisa umonakalo we-UV?
I-Palmitoyl tetrapeptide-7 iyisithombe se-immunoglobulin IgG yomuntu, enemisebenzi eminingi ye-bioactive, ikakhulukazi imiphumela ye-immunosuppressive.Ukukhanya kwe-ultraviolet kunomthelela omkhulu esikhumbeni.Imiphumela emibi evamile yokukhanya kwe-ultraviolet ebusweni imi kanje: 1, ukuguga kwesikhumba: imisebe ye-ultraviolet ...Funda kabanzi -
Iyini i-conotoxin?Ungakwazi yini ukususa imibimbi?
i-conotoxin (i-conopeptide, noma i-CTX), i-cocktail yama-peptide amaningi anobuthi akhiqizwe amashubhu anobuthi nezindlala ze-Marine gastropod invertebrate Conus (Conus).Izingxenye eziyinhloko ngamakhemikhali e-polypeptide asebenzayo acaciswe kakhulu eziteshini ezithile ze-calcium nesistimu yezinzwa ...Funda kabanzi
