Lub cev thiab tshuaj muaj zog ntawm L-leucine
Melting point 286-288 ° C Sublimation point 145-148 ° C Specific optical rotation 15.4 ° (c = 4, 6N HCl) Dej solubility 22.4 g / L (20 C)
Dawb glossy hexahedral siv lead ua los yog dawb crystalline hmoov.iab me ntsis (DL-leucine qab zib).Sublimation ntawm 145 ~ 148 ℃.Melting point 293 ~ 295 ℃ (decomposition).Nyob rau hauv lub xub ntiag ntawm hydrocarbons, qhov kev ua tau zoo yog ruaj khov nyob rau hauv cov ntxhia acid aqueous daws.Txhua g yog yaj nyob rau hauv txog 40 ml ntawm dej thiab txog 100 ml ntawm acetic acid.Me ntsis soluble hauv ethanol (0.07%), soluble hauv dilute hydrochloric acid thiab alkaline hydroxide thiab carbonate daws.Insoluble hauv ether.
Nws yog ib qho tseem ceeb amino acid, thiab cov txiv neej laus xav tau 2.2g / d (151 daim ntawv).Tsim nyog rau kev loj hlob ntawm cov me nyuam mos thiab kev saib xyuas ntawm ib txwm nitrogen tshuav nyiaj li cas rau cov neeg laus.
L-Leucine khoom siv
Khoom noj khoom haus ntxiv;flavoring thiab flavoring agent.
Kev npaj cov amino acid infusion thiab kev npaj cov amino acid ntau, cov neeg ua haujlwm hypoglycemic, cog kev loj hlob txhawb nqa.
Rau kev tshawb fawb biochemical, biochemical reagents, tshuaj amino acid.
Lub luag haujlwm ntawm L-leucine
Nws yog siv nyob rau hauv cov tshuaj rau kev kho mob thiab kev kuaj mob ntawm idiopathic hyperglycemia nyob rau hauv cov me nyuam, thiab rau kev kho mob ntawm anemia, lom, muscular dystrophy, sequelae ntawm poliomyelitis, neuritis thiab mob hlwb.
Nws yog siv rau kev kuaj mob thiab kev kho mob ntawm idiopathic hyperglycemia hauv cov menyuam yaus, kev cuam tshuam ntawm cov piam thaj metabolism, kab mob siab nrog txo cov kua tsib, ntshav tsis txaus, lom, cov leeg nqaij dystrophy, sequelae ntawm poliomyelitis, neuritis thiab mob hlwb.Mob ntshav qab zib, cerebrovascular sclerosis thiab mob raum cov neeg mob uas muaj proteinuria thiab hematuria raug kaw.Cov neeg mob uas mob plab thiab duodenal rwj yuav tsum tsis txhob noj.
Feem ntau raws li kev noj haus ntxiv, nws muaj cov txiaj ntsig ntawm kev txo cov ntshav qab zib thiab txhawb kev loj hlob.
