ʻO Glycine

ʻO Glycine(ʻO Gly i hoʻopau ʻia), i ʻike ʻia ʻo ka acetic acid, he amino acid ʻaʻole pono, ʻo kona ʻano kemika ʻo C2H5NO2. ʻO Glycine kahi amino acid o ka endogenous antioxidant emi glutathione, i hoʻohui pinepine ʻia e nā kumu exogenous i ka wā o ke kino ma lalo o ke koʻikoʻi koʻikoʻi, a i kekahi manawa i kapa ʻia ʻo ka amino acid semi-essential.

Nā waiwai kemika:

Keʻokeʻo monoclinic a i ʻole hexagonal crystal, a i ʻole ka pauka crystalline keʻokeʻo. ʻAʻala ʻole, me ka ʻono ʻono kūikawā. Hiki ke 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 100g anhydrous ethanol. Aneane hiki ʻole ke hoʻoheheʻe ʻia i ka acetone a me ka ether.

Hana hana:

ʻO ke ala Strecker a me ka chloro-acetic acid ammonification kaʻina hana nui.

Ke ala Strecker:formaldehyde, sodium cyanide, ammonium chloride reaction together, a laila hoʻohui i ka glacial acetic acid, precipitation o ka methylene aminoacetonitrile; Ua loaʻa iā Amino acetonitrile sulfate ma ka hoʻohui ʻana i ka methylene acetonitrile i ka ethanol ma ke alo o ka sulfuric acid. Hoʻopau ʻia ka sulfate e ka barium hydroxide e loaʻa ai ka paʻakai barium glycine; A laila hoʻohui ʻia ka ʻakika sulfuric e hoʻoheheʻe i ka barium, kānana iā ia, hoʻopaʻa i ka filtrate, a ma hope o ka hoʻomaloʻo ʻana e hoʻoheheʻe ʻia 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 (NH2CH2COO) 2 ba (NH2CH2COO) H2NCH2COOH

Chloro-acetic acid ammoniation ala:ʻO ka wai ammonia a me ka ammonium bicarbonate i hui pū ʻia i ka 55 ℃, e hoʻohui i ka chloro-acetic acid aqueous solution, pane no 2h, a laila hoʻomehana i 80 ℃ e wehe i ke koena amonia, decolorization me ka carbon activated, kānana. Hoʻohui ʻia ka solution decolorizing me 95% ethanol e hoʻoheheʻe ʻia ka glycine, kānana, holoi ʻia me ka ethanol a maloʻo no ka loaʻa ʻana o ka huahana pala. E hoʻoheheʻe ʻia i loko o ka wai wela a e hana hou me ka ethanol e loaʻa ai ka glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Eia kekahi, lawe ʻia ka glycine mai ka hydrolyzate silika a hydrolyzed me ka gelatin ma ke ʻano he kumu.

Kihapai meaʻai

1, hoʻohana ʻia e like me ka biochemical reagents, hiki ke hoʻohana ʻia i ka lāʻau lapaʻau, hānai a me nā mea hoʻohui meaʻai, ʻoihana hoʻomoʻa nitrogen i hoʻohana ʻia e like me ka mea hoʻohana ʻole decarbonizing;

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

3, loaʻa iā ia kekahi hopena inhibitory i ka hana hou ʻana o nā subtilis a me Escherichia coli, no laila hiki ke hoʻohana ʻia e like me ka preservative no nā huahana surimi, pīkī pīni, etc., hoʻohui i 1% ~ 2%;

4, loaʻa ka hopena antioxidant (me ka hoʻohana ʻana i kāna hui metala chelate), i hoʻohui ʻia i ka ʻaila, cheese, margarine hiki ke hoʻonui i ke ola mālama o 3 ~ 4 mau manawa;

5. No ka hoʻopaʻa ʻana i ka momona i loko o nā meaʻai i kālua 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 palaoa no ka hoʻomoʻa wikiwiki ʻana i nā noodles, hiki ke pāʻani i kahi hana hoʻolāʻau i ka manawa like;

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

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

Kahua mahiai

1. Hoʻohana nui ʻia ia e like me ka additive a me ka mea hoihoi e hoʻonui i nā waikawa amino i ka hānai no ka moa, nā holoholona, ​​​​ʻoi aku nā holoholona. Hoʻohana ʻia e like me ka hydrolyzed protein additive, ma ke ʻano he synergistic agent o hydrolyzed protein;

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

Kahua hana

1, hoʻohana ʻia e like me ka 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 ka cephalosporin maka, sulfoxamycin intermediate, imidazolacetic acid synthesis intermediate, etc.;

4, hoʻohana ʻia e like me nā mea hoʻonaninani.
