I-D-Calcium Pantothenate
Ngenisa kafushane
I-calcium pantothenate uhlobo lwe-vitamin B futhi ingenye yezakhamzimba ezibalulekile ekukhuleni okuvamile kwezinto eziphilayo. I-calcium pantothenate ikhona ngezindlela ezintathu ngoba inama-athomu e-chiral carbon: i-D L-body (hybrate), i-D-body (umzimba wesokudla) kanye ne-L-body (umzimba wesobunxele). I-D-calcium pantothenate kuphela enomsebenzi webhayoloji, enekristalu noma i-powder emhlophe noma ephuzi kancane efana nenaliti ebonakala, kanye nendawo yokuncibilika engu-195 ~ 196 ℃ (ukubola), Incibilika emanzini, i-methanol, i-glycerine, incibilika kancane ku-ethanol kanye ne-acetone, ene-hygroscopicity, imnandi kancane, kodwa ibaba kancane. Ngokuphathelene nokuzinza kwamakhemikhali, iyona ezinzile kakhulu ezixazululweni zamanzi ene-pH ephakathi kuka-5 no-7. Izinzile kakhulu emoyeni naselangeni, futhi ayizinzile kangako kuma-acid nama-alkali. Ngenisa kafushane i-calcium pantothenate uhlobo lwe-vitamin B futhi ingenye yezakhamzimba ezibalulekile ekukhuleni okuvamile kwezinto eziphilayo.
Izakhiwo zamakhemikhali
Amakristalu amhlophe, a-hygroscopic. Ayakwazi ukukhanya nomoya, kanye nesisombululo samanzi si-alkaline ebuthakathaka. Incwadi yamakhemikhali - 196°C, ukujikeleza okukhethekile. Ancibilika emanzini kanye ne-glycerin, i-acetone kanye ne-ethanol encibilikayo kancane.
SEBENZISA
Isetshenziswa kakhulu kwezokwelapha, ukudla kanye nezithasiselo zokudla. Iyingxenye ye-coenzyme A, ehlanganyela ekugayweni kwama-carbohydrate, amafutha kanye namaprotheni. Iyinto ebalulekile emzimbeni womuntu nasezilwaneni ukuze kugcinwe imisebenzi evamile yomzimba. Ngaphezu kwama-70% asetshenziswa njengezithasiselo zokudla.
Isetshenziswa ngokwezokwelapha ukwelapha ukuntuleka kwevithamini B, i-peripheral neuritis, kanye ne-intestinal colic ngemuva kokuhlinzwa. Bamba iqhaza ekugayweni kwamaprotheni, amafutha kanye noshukela emzimbeni.
