Glycine

Glycine(a na-akpọ Gly), nke a makwaara dị ka acetic acid, bụ amino acid na-adịghị mkpa, usoro kemịkalụ ya bụ C2H5NO2. Glycine bụ amino acid nke glutathione antioxidant dị n'ime ahụ, nke a na-ejikarị ihe ndị sitere na mpụga eme ihe mgbe ahụ nọ n'ọnọdụ nrụgide siri ike, a na-akpọkwa ya amino acid semi-essential mgbe ụfọdụ. Glycine bụ otu n'ime amino acid kachasị mfe.

Njirimara kemịkalụ:

Ọcha kristal monoclinic ma ọ bụ hexagonal, ma ọ bụ ntụ ntụ kristal ọcha. Enweghị isi, nwere ụtọ pụrụ iche. Ọ na-agbaze ngwa ngwa na mmiri, ọ na-agbaze na mmiri: 25g/100ml na 25℃; Na 50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml na 75℃; Na 100℃, ọ bụ 67.2g/100ml. Ọ naghị agbaze nke ukwuu na ethanol, ihe dị ka 0.06g agbaze na 100g ethanol anhydrous. Ọ fọrọ nke nta ka ọ ghara ịgbaze na acetone na ether.

Usoro mmepụta:

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

Usoro Strecker:formaldehyde, sodium cyanide, mmeghachi omume ammonium chloride ọnụ, wee tinye glacial acetic acid, mmiri ozuzo nke methylene aminoacetonitrile; E nwetara amino acetonitrile sulfate site na itinye methylene acetonitrile na ethanol n'ihu sulfuric acid. A na-agbaze sulfate ahụ site na barium hydroxide iji nweta nnu glycine barium; E mesịa, a na-agbakwunye sulfuric acid iji mee ka barium ahụ dị ọhụrụ, na-enyocha ya, na-etinye ihe nzacha ahụ n'ime ya, mgbe ọ jụrụ oyi, ọ na-eme ka kristal glycine dị ọhụrụ.

Usoro ammonia nke Chloro-acetic acid:Mmiri ammonia na ammonium bicarbonate ngwakọta ọkụ ruo 55℃, na-agbakwunye mmiri mmiri chloro-acetic acid chloro-acetic acid, mmeghachi omume maka awa 2, wee kpoo ọkụ ruo 80℃ iji wepụ ammonia fọdụrụ, na-agbanwe agba site na iji carbon arụ ọrụ, na-eme ka nzacha dị. Agbakwunyere ngwọta decolorizing na 95% ethanol iji mee ka glycine dị ka kristal, na-eme ka ọ pụta ìhè, na-asa ya na ethanol ma kpọọ nkụ iji nweta ngwaahịa ahụ. Gbazee na mmiri ọkụ ma jiri ethanol megharịa ya iji nweta glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Tinyere nke ahụ, a na-ewepụtakwa glycine site na silk hydrolysate ma jiri gelatin mee ka ọ dị ọcha dị ka ihe e ji arụ ọrụ.
