L-Tyrosine Ethyl Ester Hydrochloride (H-Tyr-OEt · HCl) (CAS: 4089-07-0) imagwiritsidwa ntchito ngati mankhwala ndi organic wapakatikati komanso ngati wothandizira wofunikira wa amino.Amagwiritsidwanso ntchito poyambitsa t-Boc kuteteza jini.Amino zidulo zotumphukira, ntchito peptide kaphatikizidwe, organic synthesis intermediates, mankhwala intermediates, zamchere zamchere reagents, mankhwala reagents.
Mau Oyamba: L-Tyrosine ndi imodzi mwa ma amino acid 20 omwe amapanga mapuloteni ndipo ndi amino acid wofunikira kwa zinyama.L-Tyrosine Ethyl Ester Hydrochloride ndiye chinthu chachikulu chopangira kaphatikizidwe ka mahomoni osiyanasiyana a peptide, maantibayotiki ndi mankhwala ena.
Ntchito: L-Tyrosine Ethyl Ester Hydrochloride ndiye chinthu chachikulu chopangira kupanga mahomoni osiyanasiyana a peptide, maantibayotiki ndi mankhwala ena.M'makampani azakudya, L-Tyrosine Ethyl Ester Hydrochloride imagwiritsidwa ntchito m'malo mwa amino acid monga zowonjezera zakudya, zomwe zimatha kusintha kukoma ndi kukoma kwa chakudya ndikuwonjezera moyo wa alumali wa chakudya.Ma amino acid ester omwe amagwiritsidwa ntchito pazakudya amawonjezeranso kusungunuka kwa ma amino acid komanso kutsimikizika kwa enzyme catalysis, yomwe imapindulitsa pakugaya ndi kuyamwa kwa thupi ndipo imagwira ntchito ziwiri pazakudya komanso chisamaliro chaumoyo.
Njira yokonzekera: Onjezani 19 mL wa anhydrous ethanol mu 250 ml ya 250 ml ya pakamwa patatu botolo yokhala ndi chovundikira, fungulo logwetsa ndi thermometer, muziziziritsa mpaka -8 ℃ mu madzi osambira amchere kuti mugwiritse ntchito kunja, pang'onopang'ono onjezerani 2.4 ml ya Sulfoxide kolorayidi pansi kusonkhezera (kutsika mathamangitsidwe ndi malire anachita kutentha osapitirira 0 ℃), pambuyo kugwetsa, kusonkhezera pa kutentha 1 h, kuwonjezera 4.5g L-Tyrosine pansi kuzirala, kwezani kutentha kwa firiji ndi kusonkhezera kwa. 2 h, ndiye kutentha ndi reflux pa 65 ℃ kwa 2 h, distill pambuyo anachita nthunzi zambiri methanol ndi owonjezera thionyl kolorayidi, kusamutsa zotsalira kwa beaker kuziziritsa, kuwonjezera 125 mL ethyl acetate kuti mpweya wochuluka wa makhiristo, vacuum. kusefera, ndi kusonkhanitsa makhiristo, L-Tyrosine Ethyl Ester Hydrochloride anapezedwa.
