L-Serine (H-Ser-OH; Chidule cha Ser kapena S) (CAS: 56-45-1) ndi amino acid, ndi imodzi mwa ma proteinogenic amino acid.Ma codons ake mu genetic code ndi UCU, UCC, UCA, UCG, AGU ndi AGC.Chifukwa cha gulu la hydroxyl, serine imayikidwa ngati polar amino acid.
Ntchito ndi Kugwiritsa ntchito L-Serine Cas 56-45-1
1. L-Serine amagwiritsidwa ntchito ngati reagent biochemical ndi zowonjezera chakudya;Amagwiritsidwa ntchito mu kafukufuku wa zamankhwala, bungwe la chikhalidwe chapakati kukonzekera, mankhwala omwe amagwiritsidwa ntchito popanga ma amino acid pazakudya zopatsa thanzi.
2. L-Serine ntchito kumunda mankhwala, L-Serine chimagwiritsidwa ntchito sintha thirdgeneration pawiri amino asidi kulowetsedwa ndi nutritionalbsupplements, ndi synthesis zosiyanasiyana silika amino acid zotumphukira, monga mtima, khansa, AIDS ndi majini. uinjiniya wa mankhwala atsopano ndi ma amino acid ena otetezedwa.Chakudya ndi chakumwa Field, L-Serine angagwiritsidwe ntchito zakumwa masewera, amino zidulo zakudya zakumwa.Kudyetsa munda, L-Serine angagwiritsidwe ntchito kudyetsa nyama, kulimbikitsa nyama kukula ndi chitukuko;
3. L-Serine imagwiritsidwa ntchito ngati chakudya chowonjezera, muzodzoladzola monga chowonjezera pakhungu.
4. Imapezeka pazofufuza zamankhwala komanso zakudya, komanso itha kugwiritsidwa ntchito ngati mphete yopangira serine.
5. L-Serine ili ndi ntchito zambiri zamankhwala.Serine imathandizira kagayidwe ka mafuta ndi mafuta acids ndikuthandizira chitetezo chamthupi.
6. L-Serine imagwiritsidwanso ntchito ngati chowonjezera cha zakudya komwe chingathandize kupititsa patsogolo kukumbukira ntchito komanso muzinthu zosamalira anthu kumene zimathandiza kupanga maselo atsopano a khungu.
7. L-Serine yakhala ikugwiritsidwa ntchito pokonzekera Tris-BSAN bafa kwa homogenization.Amagwiritsidwanso ntchito pakuwunika kuchuluka kwa ma polypeptides mumkodzo wabwinobwino.
8. L-Serine imagwiritsidwa ntchito popanga purines ndi pyrimidines monga antibacterial / antifungal agents, komanso kukhala ngati mapuloteni a proteinogenic.
9. L-Serine imayikidwa ngati amino acid osafunikira.Imagwiritsidwa ntchito ngati gawo lazofalitsa zama cell komanso zopangira zopangira zamalonda zamapuloteni ophatikizananso ndi ma antibodies a monoclonal.
10. L-Serine kupyolera mu phosphorylation-hydroxy derivative ikhoza kuperekedwa pambuyo pa ntchito zofunika za thupi za P serine ndi gawo lalikulu la phospholipids;
11. L-Serine yokhala ndi pH yokhazikika ya ntchito ya madontho a maso, madontho a maso ndi osakwiyitsa;
12. L-Serine ndi chinthu chofunika kwambiri chachilengedwe (NMF) ndi chimodzi mwa stratum corneum kuti ikhalebe ndi udindo waukulu wa madzi, L-Serine ndiyo chinsinsi cha zowonjezera zowonjezera zodzikongoletsera.
