Glycine

Glycine(nke a na-akpọ Gly), nke a makwaara dị ka acetic acid, bụ amino acid na-adịghị mkpa, usoro kemịkal ya bụ C2H5NO2.Glycine bụ amino acid nke endogenous antioxidant belatara glutathione, nke a na-agbakwunyekarị site na isi mmalite ndị dịpụrụ adịpụ mgbe ahụ nọ n'oké nrụgide. , na mgbe ụfọdụ a na-akpọ amino acid ọkara dị mkpa. Glycine bụ otu n'ime amino acid dị mfe.

Njirimara kemịkalụ:

kristal ọcha monoclinic ma ọ bụ hexagonal, ma ọ bụ kristal ọcha ntụ ntụ.Enweghị isi, nwere ụtọ ụtọ pụrụ iche.Dị mfe soluble na mmiri, solubility na mmiri: 25g / 100ml na 25 ℃;Na 50 ℃, 39.1g/10Chemicalbook0ml;54.4g / 100ml na 75 ℃;Na 100 ℃, ọ bụ 67.2g / 100ml.Na ethanol, ihe dị ka 0.06g gbazere na 100g ethanol anhydrous.Ọ fọrọ nke nta ka ọ ghara ịsacha ya na acetone na ether.

Usoro mmepụta:

Usoro strecker na usoro chloro-acetic acid ammonification bụ ụzọ nkwadebe bụ isi.

Usoro strecker:formaldehyde, sodium cyanide, ammonium chloride mmeghachi omume ọnụ, wee tinye glacial acetic acid, ọdịda nke methylene aminoacetonitrile;A nwetara Amino acetonitrile sulfate site n'ịgbakwunye methylene acetonitrile na ethanol na ọnụnọ sulfuric acid.A na-emebi sulfate site na barium hydroxide iji nweta glycine barium nnu;Mgbe ahụ, a na-agbakwunye sulfuric acid ka ọ na-ebuli barium ahụ, nyochaa ya, tinye uche na filtrate, na mgbe ọ jụrụ oyi, ọ na-ebuli kristal glycine.Nnwale [NaCN] -> [NH4Cl] CH2 = N - CH2CNCH2 = N - CH2CN [- H2SO4] -> [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, - H2SO4 [BChemicalbooka (OH) 2] - (NH2CH2CH2CON) 2 ba [- H2SO4] -> H2NCH2COOH

Usoro amoniation nke chloro-acetic acid:mmiri ammonia na ammonium bicarbonate agwakọta kpo oku na 55 ℃, na-agbakwunye chloro-acetic acid aqueous solution, mmeghachi omume maka 2h, wee kpo oku ka 80 ℃ wepụ amonia fọdụrụnụ, decolorization na carbon arụ ọrụ, filtration.Eji 95% ethanol gbakwunyere ihe ngwọta na-eme ka ọ bụrụ ihe na-eme ka glycine dị ọcha, kpochaa, saa ya na ethanol ma kpoo ya iji nweta ngwaahịa ahụ.Igbari na mmiri ọkụ na recrystalize na ethanol iji nweta glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] -> [NH4OH]

Na mgbakwunye, a na-ewepụtakwa glycine na silk hydrolyzate na hydrolyzed na gelatin dị ka akụrụngwa.
