Khoom Description
DL-alpha-Hydroxymethionine Calcium yog dab tsi?
DL-alpha-Hydroxymethionine Calcium, nws lub npe tshuaj yog Calcium 2-hydroxy-4-methylthiobutanoate, nws tus lej CAS yog 4857-44-7, nws cov mis molecular yog C10H18CaO6S2, thiab nws cov txheeb ze molecular hnyav yog 338.45. Nws yog ib qho amino acid nyob rau hauv daim ntawv ntawm calcium ntsev uas muaj cov organic sulfur, thiab cov khoom no yog ib tug dawb los yog yuav luag dawb crystalline hmoov. Nws muaj ib tug peculiar tsw thiab iab saj; Nws muaj hygroscopicity. Nws yog tsim los ntawm DL methionine, sodium nitrite, thiab concentrated sulfuric acid ua raw khoom.
Nws qhov kev tshawb pom hnub rov qab mus rau thaum ntxov xyoo pua 20th. Xyoo 1902, Swedish biochemist Kub tau tshawb pom cov amino acid tshiab, hydroxylmethionine (Hydroxylysine), tsim los ntawm hydroxylation ntawm lysine hauv collagen synthesis. Ib txoj kev tshawb fawb tom qab pom tias racemic Hydroxymethionine yog ib qho sib xyaw ntawm hydroxy-methionine, nws muaj cov qauv sib txawv thiab stereoisomers.
Xyoo 1960, cov kws tshawb fawb tau pib kawm txog nws txoj haujlwm lom neeg. Thaum pib, lawv tsuas yog xav tias racemic hydroxymethionine yog ib qho me me amino acid, tab sis nrog kev tshawb fawb ntxiv, nws tau pom tias nws tuaj yeem txhim kho kev ruaj ntseg ntawm collagen thiab calcium ion binding peev xwm, uas yog ib qho tseem ceeb rau kev noj qab haus huv ntawm lub cev pob txha thiab cov ntaub so ntswg.
Tam sim no, nws tau dhau los ua ib qho ntawm cov khoom xyaw tseem ceeb hauv kev ua haujlwm ntawm Cov Khoom Noj Qab Haus Huv, cov khoom noj khoom haus thiab cov tshuaj, Nws ua lub luag haujlwm zoo hauv kev txhawb nqa kev noj qab haus huv.
