ʻO Glycine

ʻO Glycine(ʻo Gly i hoʻopōkole ʻia), i ʻike ʻia hoʻi ʻo acetic acid, he amino acid ʻaʻole pono, ʻo kona ʻano kemika ʻo C2H5NO2. ʻO Glycine kahi amino acid o ka endogenous antioxidant reduced glutathione, kahi i hoʻohui pinepine ʻia e nā kumu exogenous ke kaumaha nui ke kino, a i kekahi manawa i kapa ʻia ʻo semi-essential amino acid. ʻO Glycine kekahi o nā amino acid maʻalahi loa.

Nā waiwai kemika:

He kristal keʻokeʻo monoclinic a hexagonal paha, a he pauka kristal keʻokeʻo paha. ʻAʻohe ʻala, me ka ʻono ʻono kūikawā. Maʻalahi ka hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka wai: 25g/100ml ma 25℃; Ma 50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml ma 75℃; Ma 100℃, he 67.2g/100ml. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka ethanol, ma kahi o 0.06g i hoʻoheheʻe ʻia i loko o 100g ethanol anhydrous. Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka acetone a me ka ether.

ʻAno hana:

ʻO ke ʻano hana Strecker a me ke ʻano ammonification chloro-acetic acid nā ʻano hana hoʻomākaukau nui.

ʻAno hana Strecker:formaldehyde, sodium cyanide, ammonium chloride reaction pū, a laila hoʻohui i ka glacial acetic acid, ka ua ʻana o ka methylene aminoacetonitrile; Ua loaʻa ka amino acetonitrile sulfate ma ka hoʻohui ʻana i ka methylene acetonitrile i ka ethanol i ke alo o ka sulfuric acid. Hoʻopau ʻia ka sulfate e ka barium hydroxide e loaʻa ai ka paʻakai glycine barium; A laila hoʻohui ʻia ka sulfuric acid e hoʻoheheʻe i ka barium, kānana iā ia, hoʻohui i ka filtrate, a ma hope o ka hoʻomaʻalili ʻana e hoʻoheheʻe i nā kristal glycine. He hoʻokolohua [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Ke ʻano ammoniation waikawa chloro-acetic:Ua hui pū ʻia ka wai ammonia a me ka ammonium bicarbonate i ka hoʻomehana ʻana i 55 ℃, me ka hoʻohui ʻana i ka hopena wai waikawa chloro-acetic, ka hopena no 2h, a laila hoʻomehana i 80 ℃ e wehe i ke koena ammonia, decolorization me ke kalapona i hoʻāla ʻia, kānana. Ua hoʻohui ʻia ka hopena decolorizing me 95% ethanol e hoʻoheheʻe i ka glycine, kānana ʻia, holoi ʻia me ka ethanol a hoʻomaloʻo ʻia e loaʻa ka huahana maka. E hoʻoheheʻe i ka wai wela a hoʻoheheʻe hou me ka ethanol e loaʻa ai ka glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Eia kekahi, ua unuhi ʻia ka glycine mai ka silika hydrolysate a ua hydrolyzed me ka gelatin ma ke ʻano he mea maka.

Kahua ʻai

1, hoʻohana ʻia e like me nā reagents biochemical, hiki ke hoʻohana ʻia i ka lāʻau lapaʻau, ka hānai a me nā mea hoʻohui meaʻai, ka ʻoihana hoʻouluulu naikokene i hoʻohana ʻia e like me ka mea hoʻopau ʻawahia ʻole;

2, hoʻohana ʻia ma ke ʻano he mea hoʻohui meaʻai, hoʻohana nui ʻia no ka mea ʻala a me nā ʻano ʻē aʻe;

3, loaʻa iā ia kekahi hopena inhibitory i ka hana hou ʻana o subtilis a me Escherichia coli, no laila hiki ke hoʻohana ʻia ma ke ʻano he mea mālama no nā huahana surimi, ka pata pīnati, a pēlā aku, e hoʻohui i ka 1% ~ 2%;

4, loaʻa ka hopena antioxidant (me ka hoʻohana ʻana i kona hui pū ʻana o ka metala chelate), i hoʻohui ʻia i ka kirīmi, ka tīhi, a me ka margarine hiki ke hoʻolōʻihi i ke ola mālama o 3 ~ 4 mau manawa;

5. No ka hoʻopaʻa ʻana i ka ʻaila poni i loko o nā mea i hoʻomoʻa ʻia, hiki ke hoʻohui ʻia ka glucose 2.5% a me ka glycine 0.5%;

6. E hoʻohui i ka 0.1% ~ 0.5% i ka palaoa huita no ka kuke wikiwiki ʻana i nā noodles, hiki ke hoʻokani i kahi hana ʻala i ka manawa like;

7, hiki i ka ʻono o ka paʻakai a me ka vīnega ke pāʻani i kahi kuleana buffer, ʻo ka nui o nā huahana paʻakai i hoʻohui ʻia he 0.3% ~ 0.7%, nā huahana waikawa 0.05% ~ 0.5%;

8, e like me kā mākou mau lula GB2760-96 hiki ke hoʻohana ʻia e like me nā mea ʻala.

Kahua mahiʻai

1. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻohui a me ka mea hoʻowalewale e hoʻonui i nā waikawa amino i ka hānai no nā manu, nā holoholona, ​​​​ʻoi aku hoʻi nā holoholona. Hoʻohana ʻia ma ke ʻano he mea hoʻohui protein hydrolyzed, ma ke ʻano he mea synergistic o ka protein hydrolyzed;

2, i ka hana ʻana o nā pesticides i hoʻohana ʻia i ka synthesis o ka pyrethroid insecticide waena glycine ethyl ester hydrochloride, hiki ke synthesized ʻia me ka fungicide isobiurea a me ka herbicide solid glyphosate.

Kahua ʻoihana

1, hoʻohana ʻia e like me ka mea hoʻohui hoʻonā plating;

2, hoʻohana ʻia i ka ʻoihana lāʻau lapaʻau, nā hoʻokolohua biochemical a me ka synthesis organik;

3, hoʻohana ʻia e like me nā mea maka cephalosporin, sulfoxamycin waena, imidazolacetic acid synthesis waena, a pēlā aku;

4, hoʻohana ʻia e like me nā mea hoʻonani maka.
