Yiyiphi impembelelo i-pentapeptide ibe nayo esikhumbeni
Kubantu abaninzi, uxinzelelo lukhawulezisa ukuguga kwesikhumba.Esona sizathu siphambili kukuhla kwe-coenzyme NAD+.Inxalenye, ikhuthaza umonakalo omkhulu wamahhala kwi-"fibroblasts," uhlobo lweeseli ezinoxanduva lokwenza i-collagen.Enye yezona zinto zidumileyo zokuchasana nokuguga yi-peptide, evuselela ...Funda ngokugqithisileyo -
Iingxaki kunye nezisombululo ze-peptide synthesis ende
Kuphando lwebhayoloji, iipolypeptides ezinolandelelwano olude zihlala zisetyenziswa.Kwiipeptides ezingaphezulu kwe-60 amino acids kulandelelwano, i-gene expression kunye ne-SDS-PAGE zisetyenziswa ngokubanzi ukuzifumana.Nangona kunjalo, le ndlela ithatha ixesha elide kwaye umphumo wokugqibela wokuhlukana kwemveliso awulungile.Umceli-mngeni...Funda ngokugqithisileyo -
IiPeptides zokwenziwa kunye neeProtheyini eziHlanganisiweyo zisebenza ngokwahlukileyo njengeAntigens
Ii-antigens zeprotheyini eziphinda zihlangane zihlala zineepitopes ezininzi ezahlukeneyo, ezinye zazo zii-epitopes ezilandelelanayo kwaye ezinye zii-epitopes zesakhiwo.Izilwa-buhlungu zePolyclonal ezifunyenwe ngogonyo lwezilwanyana ngee-antigens ze-denatured ziyimixube yee-antibodies ezikhethekileyo kwi-epitop nganye...Funda ngokugqithisileyo -
Ukuhlelwa kweepeptides ezisetyenziswa kwishishini lezobuhle
Ishishini lobuhle belisenza konke okusemandleni ukwanelisa umnqweno wabasetyhini wokubonakala bebadala.Kwiminyaka yakutshanje, iipeptide ezishushu ezisebenzayo bezisetyenziswa kakhulu kwishishini lezithambiso.Okwangoku, ziphantse zibe ngama-50 iintlobo zezinto ezisetyenziswayo eziye zaphehlelelwa ngumenzi wezithambiso owaziwayo...Funda ngokugqithisileyo -
Umahluko phakathi kwee-amino acids kunye neeprotheni
I-amino acids kunye neeprotheni zihluke kwindalo, inani le-amino acids, kunye nokusetyenziswa.Enye, Indalo eyahlukileyo 1. I-amino acids: i-carboxylic acid carbon atom kwi-athomu ye-hydrogen ithathelwa indawo yi-amino compounds.2.Khusela...Funda ngokugqithisileyo -
Isishwankathelo sokuguqulwa kweekhemikhali zeepeptides
Iipeptides luhlobo lweekhompawundi ezenziwe ngokudityaniswa kwee-amino acids ezininzi ngeebhondi zepeptide.Zikho kuyo yonke indawo kwizinto eziphilayo.Ukuza kuthi ga ngoku, amashumi amawaka eepeptides afunyenwe kwizinto eziphilayo.Iipeptides zidlala indima ebalulekileyo ekulawuleni ...Funda ngokugqithisileyo -
Iimpawu zesakhiwo kunye nokuhlelwa kweepeptide ze-transmembrane
Kukho iintlobo ezininzi ze-peptides ze-transmembrane, kwaye ukuhlelwa kwazo kusekelwe kwiipropati zomzimba kunye neekhemikhali, imithombo, iindlela zokungena, kunye nokusetyenziswa kwe-biomedical.Ngokweempawu zabo zomzimba kunye neekhemikhali, i-membrane engena kwi-peptides inoku ...Funda ngokugqithisileyo
