Glycine

Glycine(oo loo soo gaabiyo Gly), oo sidoo kale loo yaqaano acetic acid, waa amino acid aan muhiim ahayn, qaacidadeeda kiimikaad waa C2H5NO2.Glycine waa amino acid of endogenous antioxidant la dhimay glutathione, kaas oo inta badan lagu kabo ilo dibadda ah marka jidhku ku jiro cadaadis daran. , waxaana mararka qaarkood loo yaqaannaa amino acids-ka muhiimka ah.Glycine waa mid ka mid ah asiidhyada amino-ka ugu fudud.

Waxyaabaha kiimikaad:

Karistan monoclinic cad ama laba geesood ah, ama budada crystalline cad.Aan ur lahayn, oo leh dhadhan macaan oo gaar ah.Si fudud ugu milmay biyaha, milmida biyaha: 25g/100ml at 25℃;At 50℃, 39.1g/10Chemicalbook0ml;54.4g / 100ml at 75 ℃;100 ℃, waa 67.2g/100ml.Aad ayaan ugu milmi karin ethanol, qiyaastii 0.06g oo lagu milmay 100g ethanol anhydrous ah.Ku dhawaad ​​aan lagu milmi karin acetone iyo ether.

Habka wax soo saarka:

Habka Strecker iyo habka ammonification chloro-acetic acid ayaa ah hababka ugu muhiimsan ee diyaarinta.

Habka Strecker:formaldehyde, sodium cyanide, falcelinta ammonium chloride wadajir, ka dibna ku dar glacial acetic acid, roobab methylene aminoacetonitrile;Amino acetonitrile sulfate waxaa lagu helay iyadoo lagu daray methylene acetonitrile ethanol iyadoo ay jirto sulfuric acid.Sulfate-ku waxa uu burburiyaa barium hydroxide si loo helo cusbada barium glycine;Kadibna sulfuric acid ayaa lagu daraa si ay u soo dedejiso barium-ka, sifeyso, xoojiso sifeynta, ka dib marka la qaboojiyo waxay soo saartaa crystals glycine.Tijaabo [NaCN] -> [NH4Cl] CH2 = N - CH2CNCH2 = N - CH2CN [- H2SO4] -> [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, - H2SO4 [BChemicalbooka (OH) 2] - (NH2CH2CH2CON) 2 ba [- H2SO4] -> H2NCH2COOH

Habka chloro-acetic acid ammoation:biyaha ammonia iyo ammonium bicarbonate kululaynta isku qasan ilaa 55 ℃, ku daray chloro-acetic acid xal aqueous, falcelinta 2h, ka dibna kululaynta ilaa 80 ℃ si ay meesha uga saarto ammonia haraaga, decolorization leh carbon firfircoon, sifaynta.Xalka midabaynta ayaa lagu daray 95% ethanol si ay glycine-ka u soo baxdo, la sifeeyo, lagu dhaqo ethanol oo la qalajiyo si loo helo alaabta ceeriin.Ku milmi biyo kulul oo dib ugu celi ethanol si aad u hesho glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] -> [NH4OH]

Intaa waxaa dheer, glycine sidoo kale waxaa laga soo saaraa silk hydrolyzate iyo hydrolyzed leh gelatin sida alaabta ceeriin.

Beerta cuntada

1, loo isticmaalo sida reagents biochemical, sidoo kale waxaa loo isticmaali karaa daawada, quudinta iyo cuntada lagu daro, warshadaha bacriminta nitrogen loo isticmaalo sida wakiilka decarbonizing non-sun;

2, loo isticmaalo kab nafaqo ahaan, inta badan loo isticmaalo xawaashyada iyo dhinacyo kale;

3, waxay leedahay saameyn xaddidan oo gaar ah oo ku saabsan taranka subtilis iyo Escherichia coli, sidaas darteed waxaa loo isticmaali karaa sidii ilaalinta alaabta surimi, subagga lawska, iwm, ku dar 1% ~ 2%;

4, waxay leedahay saameynta antioxidant (iyadoo la adeegsanayo iskaashiga birta chelate), oo lagu daray kareemka, jiiska, margarine waxay kordhin kartaa nolosha kaydinta 3 ~ 4 jeer;

5. Si loo xasiliyo subaga ku jira alaabta la dubay, gulukoos 2.5% iyo glycine 0.5% ayaa lagu dari karaa;

6. Ku dar 0.1% ~ 0.5% burka sarreenka si aad u karisid baasto degdeg ah, kaas oo isla markaa door ka qaadan kara xawaash;

7, dhadhanka milixda iyo khalka ayaa door ka ciyaari kara, qadarka alaabta milixda lagu daray 0.3% ~ 0.7%, alaabta acid 0.05% ~ 0.5%;

8, sida waafaqsan xeerarkeena GB2760-96 waxaa loo isticmaali karaa uunsi ahaan.

Beeraha beeraha

1. Waxaa inta badan loo isticmaalaa wax lagu daro iyo soo jiidasho si loo kordhiyo amino acids ee quudinta digaaga, xoolaha, gaar ahaan xayawaanka rabaayada ah.Loo isticmaalo sida wax lagu daro borotiinka hydrolyzed, sida wakiilka isku-dhafka ah ee borotiinka hydrolyzed;

2, in wax soo saarka ee sunta cayayaanka loo isticmaalo in synthesis of pyrethroid insecticide dhexdhexaad ah glycine ethyl ester hydrochloride, sidoo kale waxaa lagu farsamayn karaa fungicide isobiurea iyo herbicide adag glyphosate.

Beerta warshadaha

1, oo loo isticmaalo sida wax lagu daro xalinta;

2, loo isticmaalo warshadaha dawooyinka, tijaabooyinka biochemical iyo synthesis organic;

3, loo isticmaalo sida cephalosporin alaabta ceeriin, sulfoxamycin dhexdhexaad ah, imidazolacetic acid synthesis dhexdhexaad ah, iwm.;

4, loo isticmaalo sidii alaabta ceeriin ee la isku qurxiyo.
