Glycine

Glycine(Hais luv gly), tseem hu ua acetic acid, yog qhov tsis muaj amino acid, nws feem ntau muab cov tshuaj lom neeg thaum lub cev tsis muaj kev ntxhov siab heev , thiab qee zaum hu ua semi-tseem ceeb amino acid.glycine yog ib qho yooj yim aminoids.

Tshuaj lom neeg cov khoom:

Dawb monoclinic lossis hexagonal lead ua, lossis cov hmoov dawb dawb. Tsis meej, nrog tshwj xeeb qab saj. Yooj yim soluble hauv dej, solubility hauv dej: 25G / 100ml ntawm 25 ℃; Ntawm 50 ℃, 39.1g / 10chemicalBook0ml; 54.4g / 100ml ntawm 75 ℃; Ntawm 100 ℃, nws yog 67.2g / 100ml. Tsis tshua muaj neeg nyob insoluble hauv ethanol, txog 0.our yaj nyob rau hauv 100g anhydrous ethanol. Yuav luag Insoluble hauv acetone thiab ether.

Txujcial Ntau Lawm:

Strecker txoj kev thiab chloro-acetic acid ammonification qauv yog qhov kev npaj loj.

Strecker Txuj Ci:formaldehyde, sodium cyanide, ammonium chloride cov tshuaj tiv thaiv ua ke, ntxiv cov hmoov av acetic acid, nag lossis daus ntawm methylene aminoacetrile; Amino Acetonitrile sulfate tau txais los ntawm kev ntxiv methylene acetonitrile rau ethanol nyob rau hauv muaj sulfuric acid. Sulfate yog decomposed los ntawm barium hydroxide kom tau glycine barium ntsev; Tom qab ntawd sulfuric acid ntxiv rau nag lossis daus siv, mloog zoo li cas lim, thiab tom qab nws ua kom txias dua glycine muaju. Kev sim [NACN ]-> [NH4CL] CH2 = n - CH2CNTH] -> h2so4] - h2so4] -> h2so4] - (nh2ch2coo) 2 ba (nh2ch2coo) 2 BA [- H2SO4] -> H2Nch2Cooh

Chloro-acetic acid ammonivers txoj kev:Cov dej cua sov thiab ammonium bicarbonate xyaw cua sov rau 55 ℃, ntxiv chloro-accet acid aqueous daws, kev txiav txim siab nrog rau cov pa roj carbon, lim. Cov kev daws teeb meem tau ntxiv nrog 95% ethanol los ua rau glycine crystallize tawm, lim, ntxuav, ntxuav nrog ethanol thiab ziab kom tau txais cov khoom nyoos. Dissolve nyob rau hauv dej kub thiab recrystallize nrog ethanol kom tau glycine. H2Nch2Cooh Clch2Cooh [NH4HCO3 ]->> [NH4OH]

Ib qho ntxiv, Glycine kuj tau muab rho tawm los ntawm silk hydrolyzate thiab hydrolyzed nrog gelatin ua cov khoom siv raw.

Daim Ntawv Thov:

Khoom Noj Khoom Haus

1, siv los ua cov tshuaj lom zem biochemical, tseem siv tau rau hauv tshuaj, pub thiab khoom noj ntxiv thiab khoom noj khoom haus cov neeg tsis muaj tshuaj lom neeg siv cov neeg saib xyuas tsis zoo;

2, siv los ua cov zaub mov noj muaj txiaj ntsig, tsuas yog siv rau seasoning thiab lwm yam;

3, Nws muaj qee yam kev txwv tsis pub muaj kev sib deev ntawm subtilis thiab escherichia coli, yog li nws tuaj yeem siv los ua cov khoom lag luam surimi, yog li nws cov txiv laum huab xeeb, ntxiv 1% ~ 2%;

4, muaj cov nyhuv antioxidant (siv nws txoj kev sib koom tes hlau), ntxiv rau cream, cheese, margarine yuav txuas ntxiv lub neej ntawm 3 ~ 4 zaug;

5. Txhawm rau ruaj khov lard nyob rau hauv cov khoom ci, flucose 2.5% thiab glycine 0.5% tuaj yeem ntxiv;

6. Ntxiv 0.1% ~ 0.5% mus rau cov hmoov nplej hmoov rau cov mij ua noj sai, uas tuaj yeem ua lub luag haujlwm raws caij nyoog tib lub sijhawm;

7, cov saj ntawm ntsev thiab vinegar tuaj yeem ua lub luag haujlwm tsis tau, tus nqi ntawm cov khoom ntsev 0.3% ~ 0.5% ~ 0.5%;

8, raws li peb cov kev cai GB2760-96 tuaj yeem siv raws li cov txuj lom.

Agricultural teb

1. Nws tsuas yog siv los ua tus ntxiv thiab nyiam ua kom cov amino acids nyob rau hauv pub rau nqaij qaib, tsiaj txhu, tshwj xeeb yog tsiaj. Siv ua cov protein hydrolyzed ntxiv, raws li tus neeg sawv cev ntawm hydrolyzed protein;

2, Hauv kev tsim cov tshuaj tua kab uas siv nyob rau hauv cov hluavtaws kab mob sib kis glycine ethloride, kuj tseem yog synthesized fungicide etobiurea thiab herbicide cov khoom glyphosate.

Muaj Daim Teb

1, siv raws li plating cov tshuaj ntxiv;

2, siv hauv kev lag luam muag tshuaj, kev ntsuam xyuas biochemical thiab synthes synthesis;

3, Siv los ua Cephaposporin Raw cov ntaub ntawv, sulfoxamycin nruab nrab, imidazolacetic acid saptthesis Qib, thiab lwm yam;

4, siv los ua kom zoo nkauj cov khoom siv.
