Glycine(whakapotohia ko Gly), e mohiotia ana ko te waikawa acetic, he waikawa amino kore-tino, ko tana tauira matū ko C2H5NO2. Ko te Glycine he waikawa amino o te antioxidant endogenous glutathione whakaitihia, he maha nga wa ka taapirihia e nga puna o waho i te wa e tino taumaha ana te tinana. , a i etahi wa ka kiia ko te waikawa amino ahua-nui. Ko te Glycine tetahi o nga waikawa amino ngawari.
Ma te monoclinic ma, he hexagonal karaihe ranei, he paura tioata ma ranei.He kakara, he reka reka motuhake.He ngawari te whakarewa ki te wai, te whakarewatanga ki te wai: 25g/100ml i te 25℃;I te 50 ℃, 39.1g/10Chemicalbook0ml;54.4g/100ml i te 75 ℃;I te 100 ℃, he 67.2g/100ml.Tino korekore ki te waiwaro, tata ki te 0.06g ka rewa ki te 100g waiwaro anhydrous.Tata korekore ki te acetone me te ether.
Tikanga whakaputa:
Ko te tikanga Strecker me te chloro-acetic acid ammonification tikanga nga tikanga whakareri matua.
Tikanga Strecker:formaldehyde, konutai cyanide, haukinia pūhaumāota tauhohenga tahi, ka tāpiri i te waikawa acetic glacial, rerenga o te methylene aminoacetonitrile;I whiwhi te Amino acetonitrile sulfate ma te taapiri i te methylene acetonitrile ki te waihano i te aroaro o te waikawa sulfuric.Ka tihorea te pūkawa e te barium hydroxide kia whiwhi ai i te tote barium glycine;Kātahi ka tāpirihia te waikawa pungatara hei whakaheke i te barium, ka tātarihia, ka whakakorikori i te filtrate, a, i muri i te whakamatao ka tohe nga tioata glycine.He whakamatautau [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2COO ba (NH2CH 2 ba [- H2SO4] – > H2NCH2COOH
Tikanga haukini waikawa Chloro-acetic:te wai haukinia me te haukinia bicarbonate whakawera whakawera ki te 55 ℃, tāpiri wairewa wai waikawa chloro-acetic, tauhohenga mo te 2h, ka whakamahana ki te 80℃ ki te tango i te haukinia toenga, te whakahekenga tae me te waro whakahohe, te tātari.I tapirihia te wairewa whakaheke tae ki te 95% ewaro kia whakapatia ai te glycine, ka tātarihia, ka horoia ki te waihano ka whakamaroke kia whiwhi ai i te hua parakore.Whakarewa i roto i te wai wera ka whakamahana ki te waihano kia whiwhi ai te glycine.H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]
I tua atu, ka tangohia ano te glycine mai i te hiraka hydrolyzate me te hydrolyzed ki te gelatin hei rauemi mata.
