Glycine

Glycine(i-gly efushanisiwe), eyaziwa nangokuthi i-acetic acid, i-acidi acid engabalulekile, ifomula yayo ebalulekile yi-C2h5no2.Glycine yi-amino acid ye-amioxious antioxidant encishisiwe i-glutathione, okuvame ukwenziwa yingcindezi enkulu , futhi kwesinye isikhathi ibizwa nge-amino acid.Glycine ingenye yama-amino acid alula.

Izakhiwo zamakhemikhali:

I-mhlophe monoclinic noma i-hexagonal crystal, noma i-white crystalline powder. I-Odorless, ngokunambitheka okuningana okumnandi. Ukuncibilika kalula emanzini, i-solubility emanzini: 25g / 100ml ngo-25 ℃; Kwa-50 ℃, 39.1g / 10chemicalbook0ml; 54.4g / 100ml ngo-75 ℃; Ku-100 ℃, kungu-67.2g / 100ml. I-insoluble ngokweqile e-ethanol, cishe ngo-0.06g inciphisiwe e-100g anhydrous ethanol. Cishe insoluble e-acetone naku-ether.

Indlela yokukhiqiza:

Indlela ye-Streeker ne-Chloro-acetic acetic abmonfication indlela yizindlela eziphambili zokulungiselela.

Indlela ye-Streeker:I-OrganDehyde, i-Sodium Cyanide, i-ammonium chloride ukusabela ndawonye, ​​bese wengeza i-glacial acetic acid, izulu le-methylene aminocetonitrite; I-Amino Acetonitrile Sulfate itholwe ngokungeza i-methylene acetonitrile ku-ethanol phambi kwe-sulfuric acid. I-sulfate ibolile nge-barium hydroxide ukuthola usawoti we-glycine barium; Ngemuva kwalokho kufakwa i-sulfuric acid ukuze uhlanganise i-barium, ukuhlunga, gxila ukugxila kwe-filtrate, futhi ngemuva kokupholisa amakristalu e-glycine. Ukuhlolwa [i-NACN] -> [NH4CL] CH2 = N - CH2CNCH2 = N - CH2CNCH2 - H2HS4] - - [C2HH4OH] - 2 BA [- H2SO4] -> H2nch2Cooh

Indlela ye-Chloro-acetic acid amobiation:I-Ammonia Water ne-Ammonia Amanzi eBicarbonate exubile ukufudumala ku-55 ℃, engeza ikhambi elinamanzi we-chloro, ukusabela kwe-2h, bese kufudumeza ku-80 ℃ ukususa ikhabhoni eyakhiwe ngensalela, ukugcotshwa. Isixazululo esihlubukayo sengezelwe nge-95% ethanol ukwenza i-glycine ikhiphe i-glycine ikhiphe, ihlanjululwe, igezwe nge-ethanol futhi yomiswe ukuthola umkhiqizo ongahluziwe. Chaza emanzini ashisayo bese uphinda uphinde nge-ethanol ukuthola i-glycine. H2nch2cooh clch2coh [nh4hco3] -> [nh4oh]

Ngaphezu kwalokho, i-glycine nayo ikhishwe kusuka ku-silk hydrolyzate kanye ne-hydrolyzed nge-gelatin njengento eluhlaza.

Isicelo:

Insimu yokudla

1, esetshenziswe njenge-reagents ye-biochemical, nayo ingasetshenziswa kwezokwelapha, okuphakelayo kanye nezithasiselo zokudla, imboni yomanyolo ye-nitrogen isetshenziswa njenge-ejenti ye-decarbonising enobuthi;

2, isetshenziswe njengesengezo sokudla okunempilo, esetshenziselwa ikakhulukazi ukuthosa nezinye izici;

I-3, inomphumela othile wokuvimbela ekukhiqizweni kwe-subtilis ne-escherhia Coli, ngakho-ke ingasetshenziswa njengokulondolozwa kwemikhiqizo ye-surimi, ibhotela lamantongomane, engeza i-1% ~ 2%;

I-4, inomphumela we-antioxidant (isebenzisa ukusebenzisana kwayo kwensimbi ye-chelate), ingezwe ku-ayisikhilimu, ushizi, imajarini kunganwebeka impilo yokugcina yezikhathi ezi-3 ~ 4;

5. Ukuqinisa i-lard ezimpahleni ezibhakiwe, u-glucose u-2,5% kanye ne-glycine 0.5% zingangezwa;

6. Faka u-0.1% ~ 0.5% ufulawa kakolweni wama-noodle wokupheka osheshayo, ongadlala indima yokuthona ngasikhathi sinye;

7, ukunambitheka kukasawoti noviniga kungadlala indima ye-buffer, inani lemikhiqizo kasawoti engezekile 0.3% ~ 0.7%, imikhiqizo ye-acid 0.5%;

8, ngokwemithetho yethu ye-GB2760-96 ingasetshenziswa njengezinongo.

Inkambu yezolimo

1. Isetshenziswa ikakhulukazi njengesengezo futhi iheha ukukhulisa ama-amino acid ekudleni izinkukhu, imfuyo, ikakhulukazi izilwane ezifuywayo. Isetshenziswa njengesengezo samaprotheni e-hydrolyzed, njenge-ejenti ye-synergistic yamaprotheni ahlotshisiwe;

2, ekukhiqizweni kwezibulala-zinambuzane ezisetshenziswa ekuhlanganiseni kwePyrethroid Insecticide Insecticide Intermedine Glycel Ether hydrochloride, nayo ingahlaziywa i-fungicide isobiurea kanye ne-herbicide glyphoteate.

Inkambu yezimboni

1, esetshenziswa njenge-platiating solution additive;

2, esetshenziswe embonini yezemithi, izivivinyo ze-biochemical kanye nokuhlanganiswa kwe-organic;

I-3, esetshenziswe njengezinto zokwakha ze-cephalosporin, sulfoxamycin Intermediate, IMIDAPOLACETIC Synthesis Intermeliate, njll;

I-4, isetshenziswa njengezinto zokudla eziluhlaza.

Ukuhlanganiswa Komkhiqizo: I-25KG / BAG

Isitoreji kufanele sibe sepholile, somile futhi umoya.
