CAS 156-57-0 cysteamine Hydrochloride

1. Taw qhia

Cysteamine hydrochloride yog ib qho siv lead ua kua mis, uas tuaj yeem yaj dej thiab cawv, yog tus neeg sawv cev ntawm ntau cov ntaub ntawv hlau, thiab yuav pom emerald ntsuab thaum nws los rau hauv kev sib cuag nrog hlau. Nws yog tsis ruaj tsis khov nyob rau hauv tshav ntuj thiab yog heev yooj yim rau huab cua oxidation. Txawm li cas los xij, nws txoj kev ua tau zoo yog nplua nuj thiab muaj yeeb yuj, thiab nws txoj kev siv tseem ceeb yog ntau heev. Nws yog ib qho mercaptoethylamine hydrochloride ntsev reductant uas tsim nyob rau hauv cov tsiaj nyeg los ntawm pantetheine tsim los ntawm degrading Coenzyme A. Nws tau raug siv los ua cystine depleting tus neeg sawv cev nrog rau cov tshuaj somatostatin inhibitor.

2. Muaj nuj nqi

2.1 Cysteamine hydrochloride siv rau kev tshawb fawb biochemical. Kev kho mob thiab tiv thaiv kev mob hluav taws xob.
2.2 Volumetric titration ntawm cobalt, npib tsib xee, tooj liab, zinc, cadmium thiab mercury. Masking tus neeg sawv cev.
2.3 Nws muaj ntau yam physiological teebmeem, xws li prolactin inhibitors, uas yuav induce duodenal rwj nyob rau hauv nas.
2.4 Qhov nruab nrab ntawm ranitidine thiab cimetidine tuaj yeem siv los ua tshuaj tua kab mob paracetamol lom.

2.5 Cov saw hloov cov neeg sawv cev hauv cov organic polymer synthesis.

2.6 Nws yog cov tshuaj hormones tseem ceeb hauv cov tsiaj, nws muaj cov txiaj ntsig ntawm kev txhawb nqa cov protein synthesis, txhawb kev loj hlob, nce rog decomposition, thiab txhim kho kev tiv thaiv.

Cov nyhuv ntawm cysteamine hydrochloride (CSH) thiab porcine somatotropin (pST)
