I-L-leucine iyi-crystalline emhlophe noma i-crystalline powder.I-amino acid engeyona i-polar, ibaba kancane ngokunambitheka, inyibilika emanzini, 23.7g/l kanye no-24.26g/l ku-20 ℃ no-25 ℃, i-acetic acid (10.9g / L), i-dilute hydrochloric acid, isixazululo se-alkali kanye isixazululo se-carbonate, esincibilika kancane otshwaleni (0.72g / L), asincibiliki ku-ether, sancibilika ku-145 ^ R 148 ℃, sonakala ngo-293-2950c, amandla adonsela phansi athi 1.29 (180C), ukuzungezisa okuthile [a] ]D20 kungu-+ 14.5 ^ ^ - + 16.0 (6mo1 / L HCl, C = 1), iphoyinti le-isoelectric ngu-5.98.:
Ikhwalithi Yomkhiqizo ihlangabezana: Ibanga lokuvutshelwa, ikhwalithi ihlangabezana ne-AJI92, USP38.
Isimo sesitoko: Ngokuvamile gcina ama-7000-8000KG esitokweni.
Isicelo: Izithako zokudla okunomsoco.Ngokuvamile esetshenziselwa isinkwa, imikhiqizo kafulawa.Yakhiwa umgqugquzeli wokukhula kwezitshalo, i-amino acid nokulungiselela ukumnika.
Ingasetshenziswa njengamakha ukuthuthukisa ukunambitheka kokudla.
Iphakheji: 25kg / umgqomo
Ingasetshenziswa ngokuphepha ekudleni.
[iphakheji]: ingapakishwa esikhwameni sephepha se-kraft noma ebhakedeni lephepha, elinenetha engama-25kg esikhwameni ngasinye (ibhakede).Ingabuye ipakishwe ngokwezidingo zomsebenzisi.
[Ezokuthutha]: ukulayisha okulula kanye nokwehliswa okulula ukuze kuvinjelwe umonakalo wephakheji, ilanga nemvula, hhayi ngezinto ezinobuthi neziyingozi.Akuyona impahla eyingozi.
[isitoreji]: Lo mkhiqizo kufanele ugcinwe endaweni epholile, eyomile, ehlanzekile futhi enomthunzi.Kwenqatshelwe ngokuphelele ukuxuba nezinto ezinobuthi neziyingozi ukugwema ukungcola.
Ikristalu ecwebezelayo eyi-hexahedral emhlophe noma i-crystalline powder emhlophe.Ibaba kancane.I-Sublimate ku-145 ~ 148 ℃.Iphuzu elincibilikayo 293 ~ 295 ℃ (ukubola).Lapho kukhona ama-hydrocarbons, izinzile kusisombululo se-aqueous acid ye-inorganic.Igramu ngayinye ichithwa emanzini angu-40 ml kanye ne-acetic acid engaba ngu-100 ml.Incibilika kancane ku-ethanol, i-dilute hydrochloric acid, i-alkaline hydroxide nesisombululo se-carbonate.Ayincibiliki ku-ether.
1. Kuyi-amino acid ebalulekile.Isidingo samadoda amadala singu-2.2g/d, okudingekayo ekukhuleni okuvamile kwezinsana kanye nebhalansi evamile ye-nitrogen yabantu abadala.Njengesengezo sokudla okunempilo, isetshenziselwa ukulungisa ukumnika kwe-amino acid kanye nokulungiswa okuphelele kwe-amino acid, i-ejenti ye-hypoglycemic kanye nomgqugquzeli wokukhula kwezitshalo.Ngokusho kwe-GB 2760-86, ingasetshenziswa njengamakha.
2. Njengoba ukumnika amino acid kanye olunzulu amino acid ukulungiselela.Isetshenziselwa ukuxilongwa nokwelashwa kwe-idiopathic hyperglycemia ezinganeni.Ibuye ilungele ukuphazamiseka kwe-glucose metabolism, izifo zesibindi ngokuncipha kwe-bile secretion, i-anemia, ubuthi, i-muscular atrophy, i-sequelae ye-poliomyelitis, i-neuritis kanye ne-psychosis.
