L-Serine muaj cov khoom nram qab no:
1. Cov tsos: cov xim tsis muaj xim lossis dawb crystalline hmoov;
2. Solubility: soluble nyob rau hauv dej, me ntsis soluble nyob rau hauv cawv, yuav luag insoluble nyob rau hauv ether thiab ether solvents;
3. melting point: txog 228-232 ℃;
4. saj: nrog me ntsis qab zib saj.
L-Serine ua lub luag haujlwm tseem ceeb hauv biology, xws li:
1. protein synthesis: raws li ib yam ntawm cov amino acid, L-Serine yog ib feem tseem ceeb ntawm cov protein synthesis, koom tes hauv cell loj hlob, kho thiab metabolism;
2. Biocatalyst: L-Serine yog ib hom biocatalyst, uas tuaj yeem siv los tsim cov tshuaj bioactive, xws li enzymes thiab tshuaj.
L-Serine tuaj yeem npaj tau los ntawm ob txoj hauv kev: synthesis thiab extraction:
1. Txoj kev sib xyaw ua ke: L-Serine tuaj yeem tsim los ntawm cov tshuaj tiv thaiv hluavtaws. Cov txheej txheem synthesis feem ntau suav nrog cov tshuaj synthesis thiab enzyme catalysis;
2. Txoj kev rho tawm: L-Serine tuaj yeem muab rho tawm los ntawm cov khoom siv ntuj, xws li cov kab mob, fungi lossis cov nroj tsuag los ntawm fermentation.
Hais txog cov ntaub ntawv kev nyab xeeb, L-Serine yog ib qho tseem ceeb amino acid rau tib neeg lub cev thiab feem ntau suav hais tias muaj kev nyab xeeb. Txawm li cas los xij, kev noj ntau dhau tuaj yeem ua rau qee qhov kev mob tshwm sim, xws li mob plab hnyuv thiab ua xua. Hauv cov neeg uas muaj kev fab tshuaj hnyav, kev raug L-Serine tuaj yeem ua rau muaj kev fab tshuaj. Thaum siv L-Serine, nws raug nquahu kom siv raws li cov lus qhia ntawm cov kws kho mob lossis cov kws tshaj lij, thiab tswj hwm cov tshuaj kom nruj.
