I-Glycine

I-Glycine(i-Gly efinyeziweyo), ekwaziwa ngokuba yi-acetic acid, yi-amino acid engabalulekanga, ifomula yayo yekhemikhali yi-C2H5NO2. I-Glycine yi-amino acid ye-antioxidant engapheliyo encitshisiweyo yi-glutathione, edla ngokuncediswa zimithombo zangaphandle xa umzimba uphantsi koxinzelelo olukhulu, kwaye ngamanye amaxesha ibizwa ngokuba yi-amino acid engabalulekanga kangako. I-Glycine yenye yezona amino acid zilula.

Iimpawu zekhemikhali:

I-crystal emhlophe okanye i-crystal enesiqingatha, okanye umgubo omhlophe wekristale. Ayinavumba, inencasa emnandi ekhethekileyo. Inyibilika lula emanzini, inyibilika emanzini: 25g/100ml kwi-25℃; Kwi-50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml kwi-75℃; Kwi-100℃, yi-67.2g/100ml. Ayinyibiliki kakhulu kwi-ethanol, malunga ne-0.06g inyibilike kwi-100g ye-ethanol engenamanzi. Phantse ayinyibiliki kwi-acetone kunye ne-ether.

Indlela yokuvelisa:

Indlela yeStrecker kunye nendlela ye-chloro-acetic acid ammonification zezona ndlela ziphambili zokulungiselela.

Indlela yeStrecker:i-formaldehyde, i-sodium cyanide, i-ammonium chloride reaction kunye, emva koko yongeza i-glacial acetic acid, i-precipitate ye-methylene aminoacetonitrile; I-Amino acetonitrile sulfate ifunyenwe ngokongeza i-methylene acetonitrile kwi-ethanol xa kukho i-sulfuric acid. I-sulfate iboliswa yi-barium hydroxide ukuze kufunyanwe ityuwa ye-glycine barium; Emva koko i-sulfuric acid yongezwa ukuze i-barium ikhawuleze, iyihluze, igxininise i-filtrate, kwaye emva kokuba ipholile ikhawuleze iikristale ze-glycine. Uvavanyo [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Indlela ye-ammoniation ye-chloro-acetic acid:amanzi e-ammonia kunye ne-ammonium bicarbonate exutyiweyo yokufudumeza ukuya kuma-55℃, kongezwa isisombululo samanzi se-chloro-acetic acid, impendulo kangangeeyure ezi-2, emva koko kufudunyezwe ukuya kuma-80℃ ukususa i-ammonia eseleyo, ukususwa kombala nge-activated carbon, ukuhluzwa. Isisombululo sokususa umbala songezwe nge-95% ye-ethanol ukwenza i-glycine ikhanye, ihluzwe, ihlanjwe nge-ethanol kwaye yomiswe ukuze kufumaneke imveliso ekrwada. Yinyibilikise emanzini ashushu kwaye uphinde uyivuselele nge-ethanol ukuze ufumane i-glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Ukongeza, i-glycine ikwakhutshwa kwi-silk hydrolyzate ize ifakwe i-hydrolyzed nge-gelatin njengezinto eziluhlaza.
