Hydroxyethylpiperazine Ethane Sulfonic Acid

Hydroxyethylpiperazine ethane sulfonic acid (HEPES) yog zwitterionic buffering compound nquag siv hauv kev tshawb fawb lom neeg thiab biochemical. Nws yog feem ntau siv los tswj cov pH stability ntawm cell kab lis kev cai xov xwm, cov ntsiab lus protein, thiab ntau yam lom buffers.

HEPES yog ib qho derivative ntawm piperazine, cyclic organic compound. Nws muaj lub nplhaib piperazine nrog ob pawg ethyl thiab ib pawg hydroxyethyl txuas rau nws, nrog rau sulfonic acid pawg (-SO3H) tom kawg ntawm cov molecule. Cov pab pawg sulfonic acid muab cov dej solubility thiab ua rau nws muaj qhov tsis zoo ntawm lub cev pH.

Ib qho laj thawj tseem ceeb ntawm kev siv HEPES ua qhov tsis yog nws tus nqi pKa, uas yog nyob ib puag ncig 7.5 ntawm chav tsev kub. Qhov no txhais tau hais tias HEPES tuaj yeem tswj hwm qhov pH ruaj khov hauv lub cev muaj zog, ua rau nws tsim nyog rau ntau yam kev siv roj ntsha. Nws yog dav siv hauv kab lis kev cai ntawm tes, tshuaj ntsuam enzyme, electrophoresis, thiab molecular biology cov txheej txheem.

Nws dav siv nyob rau hauv tshuaj pleev ib ce khoom.

Txoj Cai ntawm Exfoliation:

Tib neeg daim tawv nqaij tau muab faib ua epidermis, dermis thiab cov ntaub so ntswg subcutaneous. Lub epidermis yog tsim los ntawm sab nrauv

Inwardly, nws yuav muab faib ua stratum corneum, pob tshab txheej, granular txheej, spinous txheej, thiab basal txheej. Exfoliation yog hais txog kev tshem tawm ntawm txheej txheej ntawm daim tawv nqaij - lub stratum corneum nyob rau hauv lub epidermis qub tuag horny.

Thaum daim tawv nqaij metabolism tsis ua hauj lwm zoo, lub stratum corneum tsis tuaj yeem raug tshem tawm ib txwm, thiab lub npe hu ua cov tawv nqaij laus tuag lawm. Thaum cov laus tuag ntawm daim tawv nqaij sib sau ua ke ntev, nws yooj yim rau txhaws qhov pores thiab tiv thaiv cov khoom tu tawv nqaij los ntawm kev nqus.

Hydroxyethylpiperazine ethane sulfonic acid muaj cov nyhuv ntawm loosening cuticles, uas muaj peev xwm pab tshem tawm cov laus cuticles ntawm daim tawv nqaij nto, thiab tom qab hydroxyethylpiperazineethanesulfonic acid softens los yog tshem tawm cov stratum corneum, lwm yam active khoom xyaw yuav nkag tau yooj yim rau hauv daim tawv nqaij.

Hydroxyethylpiperazine Ethane Sulfonic Acid hauv Kev Kho Hniav:
