Tertomothide othandizira / 922174-60-5 / pokonzekera

Kaonekeswe

Tertomotide ndi katemera wa peputide zopangidwa ndi polypeptide yopangidwa ndi ma amino acid, omwe amaphatikizapo kutsatira magulu ochokera kwa anthu a telomathet resurm discrem (TERT). Imakhala ndi zotsatira zamitsempha ndipo zitha kugwiritsidwa ntchito pofufuza zokhudzana ndi matenda a ukalamba ndi Alzheimer's.

FAQ：

Kodi Peptides ndi chiyani?

Peptides ndi mamolekyulu ofupikira opangidwa ndi amino acid olumikizidwa pamodzi ndi zomangira zokopa pangozi. Nthawi zambiri amakhala ndi 2 mpaka 70 amino acid.

Kodi gawo la Peptides ku skincare ndi chiyani?

 Ma Peptudes ali ndi ntchito zosiyanasiyana pa skincare zinthu, kuphatikiza:

Kunyowa: Pepsides amatha kuthandiza khungu kusunga chinyezi ndikuwonjezera hydration.

Anting-ukalamba: Pepside amatha kulimbikitsa kupanga Contragen, kuchepetsa makwinya, ndikusintha khungu.

Zoyera: Ma Peptides ena amatha kuyika kupanga melalanin ndikuwalitsa mawanga.

Kukonza: Pepside amatha kulimbikitsa ma cell metabolism ndikuthandizira kukonza khungu lowonongeka.

Kodi ma peptides okhala ndi cys amachepetsedwa?

Ngati peptide sanapezeke kukhala oxidized, sitikuchepetsa ma cys. Onse a polypeptides onse amapezeka kuchokera ku mtundu wopanda pake kuyeretsedwa ndi lyophilized pansi pa PH2, zomwe mwina mwina zimalepheretsa ma okosi a CYJ. Peptides okhala ndi ziphuphu zimayeretsedwa ku Ph2 pokhapokha ngati pali chifukwa china choyeretsera pa Ph6.8. Ngati kuyeretsa kumachitika pa Ph6.8, chinthu choyeretsedwa kuyenera kuthandizidwa ndi acidi nthawi yomweyo kupewa maxianation. Mu gawo lomaliza lolamulira, chifukwa cha ma cys, ngati kukhalapo kwa zolemera za madokotala (2p + h) pamapu a MS, zikuwonetsa kuti kuchepa kwapangidwa. Ngati palibe vuto ndi ms ndi hplc, tidzapereka mwachindunji ndi kutumiza katunduyo popanda kukonzanso kwina. Tiyenera kudziwa kuti peptides okhala ndi ma cys oxidation osakhalitsa nthawi yayitali, ndipo kuchuluka kwa makutidwe ndi peptide motsatizana ndi malo osungira.

Ndikufuna peptide wa cyclica, yomwe ili ndi tryptophan, kodi idzakhala oxidid?

Makutidwenation a tryptophan ndi chinthu wamba ku Peptide makutidwe, ndipo ma peptides nthawi zambiri amasambira musanayeretsedwe. Ngati makutidwe otsatsa a tryptophan amapezeka, nthawi yosungayisa ya peputiyi pa HPLC Column isintha, ndipo makutidwewo amatha kuchotsedwa ndikuyeretsa. Kuphatikiza apo, ma peptiddid amapezekanso amatha kupezekanso ndi ms.

Kodi mungasankhe bwanji mawonekedwe amchere?

Kusankhidwa kwa mawonekedwe amchere amafunika kuona zinthu zosiyanasiyana, kuphatikizapo kutsatira njira ya peptide, kukhazikika, kusinthika, biothexity, ndi zofunikira komanso zoyeserera. Mwa kusasinthika, ma peptides nthawi zambiri amatumizidwa ngati trifluohric asidi (TFA) mchere; Kuphatikiza apo, ma peptides amathanso kumafomu monga acetate, ammonium, ndi mchere wa sodium.
