Glycine

Glycine(e khutsufalitsoeng ka Gly), e tsejoang hape e le acetic acid, ke amino acid e seng ea bohlokoa, mokhoa oa eona oa lik'hemik'hale ke C2H5NO2. Glycine ke amino acid ea glutathione e fokolitsoeng ke antioxidant ea tlhaho, eo hangata e tlatsetsoang ke mehloli ea kantle ha 'mele o le tlas'a khatello e matla,' me ka linako tse ling e bitsoa amino acid e semi-essential. Glycine ke e 'ngoe ea li-amino acid tse bonolo ka ho fetisisa.

Litšobotsi tsa lik'hemik'hale:

Kristaro e tšoeu e le 'ngoe kapa e nang le mahlakore a tšeletseng, kapa phofo e tšoeu e nang le kristale. Ha e na monko, e na le tatso e monate e ikhethang. E qhibiliha habonolo metsing, e qhibiliha ka metsing: 25g/100ml ho 25℃; Ho 50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml ho 75℃; Ho 100℃, ke 67.2g/100ml. Ha e qhibilihe haholo ka har'a ethanol, hoo e ka bang 0.06g e qhibilihisitsoeng ka har'a ethanol e nang le metsi a 100g. E batla e sa qhibilihe ka har'a acetone le ether.

Mokhoa oa tlhahiso:

Mokhoa oa Strecker le mokhoa oa chloro-acetic acid ammonification ke mekhoa e meholo ea ho lokisa.

Mokhoa oa Strecker:formaldehyde, sodium cyanide, ammonium chloride reaction hammoho, ebe o eketsa glacial acetic acid, ho namela ha methylene aminoacetonitrile; Amino acetonitrile sulfate e fumanoe ka ho eketsa methylene acetonitrile ho ethanol moo ho nang le sulfuric acid. Sulfate e bolisoa ke barium hydroxide ho fumana letsoai la glycine barium; Ebe sulfuric acid e eketsoa ho namela barium, ho e sefa, ho tsepamisa filtrate, mme ka mora ho e phodisa e namela likristale tsa glycine. Teko [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Mokhoa oa ho tlosa chloro-acetic acid ammoniation:metsi a ammonia le ammonium bicarbonate e futhumatsoang ho fihlela ho 55℃, ho eketsoa tharollo ea metsi ea chloro-acetic acid, karabelo ea lihora tse 2, ebe e futhumatsoa ho fihlela ho 80℃ ho tlosa ammonia e setseng, ho tlosa 'mala ka khabone e sebetsang, ho sefa. Tharollo ea ho tlosa 'mala e ile ea eketsoa ka 95% ethanol ho etsa hore glycine e khanye, e sefshoe, e hlatsuoe ka ethanol 'me e ome ho fumana sehlahisoa se tala. Qhibiliha ka metsing a chesang 'me u boele u e sebelise ka ethanol ho fumana glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Ho phaella moo, glycine e boetse e ntšoa ho silika hydrolysate mme e hydrolyzed ka gelatin e le thepa e tala.
