Glycine

Glycine(mu magambo ahinnye Gly), izwi kandi nka aside asetiki, ni aside amine itari ngombwa, formula yayo ya shimi ni C2H5NO2. Glycine ni aside amine ya glutathione igabanya antioxydant, akenshi ikongerwamo n'ibintu biva hanze iyo umubiri uri mu stress ikomeye, kandi rimwe na rimwe yitwa aside amine y'ingenzi. Glycine ni imwe muri aside amine zoroshye cyane.

Imiterere y'ibinyabutabire:

Ifu y'umweru y'ivuriro rimwe cyangwa iy'umweru, cyangwa ifu y'umweru y'ivuriro. Nta mpumuro, ifite uburyohe bwihariye. Yoroshye gushonga mu mazi, ishonga mu mazi: 25g/100ml kuri 25℃; Kuri 50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml kuri 75℃; Kuri 100℃, ni 67.2g/100ml. Ntishongera cyane muri ethanol, hafi 0.06g ishongera muri 100g ethanol y'amazi. Hafi cyane ntishongera muri acetone na ether.

Uburyo bwo gukora:

Uburyo bwa Strecker n'uburyo bwa aside chloro-acetic ammonization ni bwo buryo bw'ingenzi bwo gutegura.

Uburyo bwa Strecker:formaldehyde, sodium cyanide, ammonium chloride reaction hamwe, hanyuma hongerwamo aside glacial acetic, methylene aminoacetonitrile; Amino acetonitrile sulfate yabonetse hashyizweho methylene acetonitrile muri ethanol mu gihe aside sulfurike irimo. Sulfate irabozwa na barium hydroxide kugira ngo haboneke umunyu wa glycine barium; Hanyuma aside sulfurike yongerwamo kugira ngo barium itere imbere, iyiyungurure, ihuze filtrate, hanyuma nyuma yo gukonjesha igatuma kristu za glycine zitera imbere. Igerageza [NaCN] – > [NH4Cl] CH2 = N – CH2CNCH2 = N – CH2CN [- H2SO4] – > [C2H5OH] H2NCH2CN, H1SO4H2NCH2CN, – H2SO4 [BChemicalbooka (OH) 2] – (NH2CH2COO) 2 ba (NH2CH2COO) 2 ba [- H2SO4] – > H2NCH2COOH

Uburyo bwo guteranya aside ya Chloro-acetic:Amazi ya amoniya na bicarbonate ya ammoniya bivanze bishyushya kugeza kuri 55°C, bongeramo umuti w'amazi wa aside chloro-acetic, bagakora amasaha 2, hanyuma bashyushya kugeza kuri 80°C kugira ngo bakureho amoniya isigaye, bahindure ibara hakoreshejwe karubone ikora, bayungurure. Umuti uhindura ibara wongewemo 95% bya ethanol kugira ngo glycine ihinduke, iyungururwe, yozwe na ethanol hanyuma yumuke kugira ngo umusaruro uvanwemo. Shyiramo mu mazi ashyushye hanyuma wongere uhindure ethanol kugira ngo ubone glycine. H2NCH2COOH ClCH2COOH [NH4HCO3] – > [NH4OH]

Byongeye kandi, glycine ivanwa muri hydrolyzate ya silk hanyuma igashyirwamo gelatin nk'ibikoresho fatizo.

Porogaramu:

Umurima w'ibiribwa

1, ikoreshwa nk'ibinyabutabire bya biochemical, ishobora no gukoreshwa mu buvuzi, mu biryo no mu nganda z'ifumbire ya azote ikoreshwa nk'ikintu kidahumanya ikirere;

2, ikoreshwa nk'inyongeramusaruro, ikoreshwa cyane cyane mu guteka ibirungo n'ibindi bintu;

3, ifite ingaruka zimwe na zimwe ku kugabanya ikwirakwira rya subtilis na Escherichia coli, bityo ishobora gukoreshwa nk'ikintu kirinda ubushyuhe ku bicuruzwa bya surimi, amavuta y'ubunyobwa, nibindi, wongereho 1% ~ 2%;

4, ifite ingaruka zo kurwanya antioxydant (ikoresheje ubufatanye bwayo na chelate y'icyuma), yongewe muri crème, foromaje, margarine ishobora kongera igihe cyo kubika inshuro 3 ~ 4;

5. Kugira ngo amavuta akomere mu biryo bitetse, isukari 2.5% na glycine 0.5% birashobora kongerwamo;

6. Ongeraho 0.1% ~ 0.5% ku ifu y'ingano kugira ngo uteke vuba, ibi bikaba bishobora kugira uruhare mu guteka icyarimwe;

7, uburyohe bw'umunyu na vinegere bishobora kugira uruhare mu gukurura, ingano y'ibikomoka ku munyu byongewemo 0.3% ~ 0.7%, ibikomoka kuri aside 0.05% ~ 0.5%;

8, dukurikije amabwiriza yacu ya GB2760-96, ishobora gukoreshwa nk'ibirungo.

Ubuhinzi

1. Ikoreshwa cyane cyane nk'inyongeramusaruro no gukurura aside amine mu biryo by'inkoko, amatungo, cyane cyane amatungo. Ikoreshwa nk'inyongeramusaruro ya poroteyine ya hydrolyzed, nk'umusemburo w'ubufatanye bwa poroteyine ya hydrolyzed;

2, mu gukora imiti yica udukoko ikoreshwa mu gukora imiti yica udukoko ya pyrethroid insecticide intermediate glycine ethyl ester hydrochloride, ishobora kandi gukorwamo fungicide isobiurea na herbicide solid glyphosate.

Urugaga rw'inganda

1, ikoreshwa nk'inyongeramusaruro yo gutwikira;

2, ikoreshwa mu nganda zikora imiti, ibizamini bya biokemike no mu gukora organic synthesis;

3, ikoreshwa nk'ibikoresho fatizo bya cephalosporin, sulfoxamycin intermediate, imidazolacetic aside synthesis intermediate, nibindi;

4, ikoreshwa nk'ibikoresho fatizo byo kwisiga.
