Glycine

Glycine(whakarāpopototanga Gly), e mōhiotia ana ko te waikawa acetic, he waikawa amino kore-tino nui, ko tōna tauira matū ko C2H5NO2. Ko te Glycine he waikawa amino o te glutathione whakaheke-aukati-roto, e tāpirihia ana e ngā pūtake o waho ina pāngia te tinana e te ahotea nui, ā, i ētahi wā ka kiia ko te waikawa amino haurua-tino nui. Ko te Glycine tētahi o ngā waikawa amino tino māmā.

Ngā āhuatanga matū:

He tioata mā kotahi-whakamārama, he tioata hexagonal rānei, he paura tioata mā rānei. Kāore he kakara, he reka motuhake. He ngāwari te wairewa ki te wai, te wairewa 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. Kāore e wairewa i roto i te etanoru, tata ki te 0.06g ka wairewa ki roto i te 100g etanoru waikore. Tata kore e wairewa ki roto i te acetone me te ether.

Tikanga whakaputa:

Ko te tikanga Strecker me te tikanga ammonification waikawa chloro-acetic ngā tikanga matua mō te whakarite.

Tikanga Strecker:Te tauhohenga o te formaldehyde, te konutai cyanide, te ammonium chloride, kātahi ka tāpirihia te waikawa acetic glacial, ka whakapūtā te methylene aminoacetonitrile; I whiwhihia te amino acetonitrile sulfate mā te tāpiri i te methylene acetonitrile ki te etanoru i te aroaro o te waikawa whanariki. Ka whakapōreareahia te sulfate e te barium hydroxide hei whiwhi i te tote glycine barium; Kātahi ka tāpirihia te waikawa whanariki hei whakapūtā i te barium, tātarihia, whakakōkīhia te tātari, ā, i muri i te whakamatao ka whakapūtā ngā tioata glycine. He whakamātautau [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Tikanga whakaamonia waikawa chloro-acetic:I konatunatua te wai haukini me te haukini paikāpōnate, ka whakamahanahia ki te 55℃, ka tāpirihia he wai waikawa chloro-acetic, ka tauhohe mō te 2 hāora, kātahi ka whakamahanahia ki te 80℃ hei tango i te haukini toenga, ka tangohia te tae ki te waro whakahohe, ka tātarihia. I tāpirihia te wai tango tae ki te 95% etanoru kia puta te glycine, ka tātarihia, ka horoia ki te etanoru, ka whakamarokehia kia puta te hua mata. Ka rewa ki te wai wera, ka tāpirihia anō ki te etanoru kia puta te glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Hei tāpiritanga, ka tangohia mai hoki te glycine mai i te hiraka hydrolyzate, ā, ka hydrolyzed ki te gelatin hei rauemi mata.
