I-L-leucine yikristale emhlophe okanye i-crystalline powder.Yi-amino acid engeyiyo-polar, ikrakra kancinci kwincasa, inyibilika emanzini, 23.7g/l kunye ne-24.26g/l ku-20 ℃ kunye ne-25 ℃, i-acetic acid (10.9g / L), i-dilute hydrochloric acid, isisombululo sealkali kunye isisombululo carbonate, i-soluble kancinane etywaleni (0.72g / L), enganyibilikiyo kwi-ether, i-sublimated kwi-145 ^ R 148 ℃, ibole ngo-293-2950c, ubunzima obuthile 1.29 (180C), ukujikeleza okuthe ngqo [a] ]D20 yi + 14.5 ^ ^ 14.5 ^ ^ - + 16.0 (6mo1 / L HCl, C = 1), indawo ye-isoelectric yi-5.98.:
Umgangatho weMveliso udibana: Ibakala lokuvuthela, umgangatho udibana ne-AJI92, USP38.
Ubume besitokhwe: Ngokuqhelekileyo gcina i-7000-8000KGs kwisitokhwe.
Isicelo: izongezo zesondlo.Ngokuqhelekileyo isetyenziselwa isonka, iimveliso zomgubo.Iqulethwe ngumgqugquzeli wokukhula kwezityalo, i-amino acid kunye nokulungiswa kwe-infusion.
Ingasetyenziswa njengesiqholo ukuphucula incasa yokutya.
Iphakheji: 25kg / umgqomo
Ingasetyenziswa ngokukhuselekileyo ekutyeni.
[iphakheji]: inokupakishwa kwi-kraft paper bag okanye kwibhakethi yephepha, kunye nomxholo we-net we-25kg kwisikhwama ngasinye (ibhakethi).Isenokupakishwa ngokweemfuno zabasebenzisi.
[Uthutho]: ukulayishwa okulula kunye nokukhulula ukukhanya ukukhusela umonakalo wephakheji, ilanga nemvula, kungekhona ngezinto ezinetyhefu neziyingozi.Ayizompahla ezingenabungozi.
[Ukugcinwa]: Le mveliso kufuneka igcinwe kwindawo epholileyo, eyomileyo, ecocekileyo kunye ne-shading.Akuvumelekanga ngokungqongqo ukuxuba izinto ezinobuthi kunye neziyingozi ukuphepha ukungcola.
Ikristale emhlophe ecwebezelayo eyihexahedral okanye umgubo omhlophe wekristale.Ikrakra kancinci.I-Sublimate kwi-145 ~ 148 ℃.Indawo yokunyibilika 293 ~ 295 ℃ (ukubola).Phambi kwee-hydrocarbons, izinzile kwisisombululo esinamanzi se-asidi ye-inorganic.Igram nganye ichithwa kwi-40 ml yamanzi kunye ne-100 ml ye-acetic acid.I-soluble kancinane kwi-ethanol, i-dilute hydrochloric acid, i-alkaline hydroxide kunye nesisombululo se-carbonate.Ayinyibiliki kwi-ether.
1. Yi-amino acid ebalulekileyo.Imfuno yamadoda amadala yi-2.2g / d, eyimfuneko ekukhuleni okuqhelekileyo kweentsana kunye ne-nitrogen balance balance of abadala.Njengesongezelelo sesondlo, sisetyenziselwa ukulungiselela ukunyuswa kwe-amino acid kunye nokulungiswa kwe-amino acid ebanzi, i-agent ye-hypoglycemic kunye nomgqugquzeli wokukhula kwezityalo.Ngokutsho kwe-GB 2760-86, inokusetyenziswa njenge-perfume.
2. Njengoko i-amino acid infusion kunye nokulungiswa kwe-amino acid ebanzi.Isetyenziselwa ukuxilongwa kunye nonyango lwe-idiopathic hyperglycemia ebantwaneni.Kwakhona ifanelekile ukuphazamiseka kwe-glucose metabolism, izifo zesibindi kunye nokunciphisa i-bile secretion, i-anemia, ityhefu, i-muscular atrophy, i-sequelae ye-poliomyelitis, i-neuritis kunye ne-psychosis.
