I-D-calcium PANTOTHENATE
Yazisa ngokufutshane
I-calcium pantothenate luhlobo lwe-vitamin B kwaye yenye yezona zinto zibalulekileyo ekukhuleni okuqhelekileyo kwezinto eziphilayo. I-calcium pantothenate ikhona kwiindlela ezintathu kuba inee-athomu ze-chiral carbon: i-D L-body (hybrate), i-D-body (umzimba wasekunene) kunye ne-L-body (umzimba wasekhohlo). Yi-D-calcium pantothenate kuphela enomsebenzi webhayoloji, enekristale emhlophe okanye emthubi kancinci okanye umgubo ofana nenaliti, kunye nendawo yokunyibilika ye-195 ~ 196 ℃ (ukubola), Inyibilika emanzini, i-methanol, i-glycerine, inyibilika kancinci kwi-ethanol kunye ne-acetone, ene-hygroscopicity, imnandi kancinci, kodwa ikrakra kancinci. Ngokuphathelele uzinzo lweekhemikhali, yeyona izinzileyo kwizisombululo zamanzi ene-pH ephakathi kwe-5 kunye ne-7. Izinzile ngakumbi emoyeni naselangeni, kwaye ayizinzile kangako kwi-asidi kunye ne-alkalis. Ngenisa ngokufutshane i-calcium pantothenate luhlobo lwe-B vitamin kwaye yenye yezona zinto zibalulekileyo ekukhuleni okuqhelekileyo kwezinto eziphilayo.
Iipropati zekhemikhali
Iikristale ezimhlophe, ezithambileyo. Ziyakwazi ukukhanya nomoya, kwaye isisombululo samanzi sinyibilika kwi-alkaline. Incwadi yekhemikhali-196°C, ukujikeleza okukhethekileyo. Inyibilika emanzini nakwi-glycerin, inyibilika kancinci kwi-acetone nakwi-ethanol.
SEBENZISA
Isetyenziswa kakhulu kumayeza, ukutya kunye nezongezo zokutya. Liyinxalenye ye-coenzyme A, ethatha inxaxheba kwi-metabolism yee-carbohydrate, amafutha kunye neeproteni. Liyinto efunekayo emzimbeni womntu nakwizilwanyana ukugcina imisebenzi eqhelekileyo yomzimba. Ngaphezulu kwe-70% isetyenziswa njengezongezo zokutya.
Isetyenziselwa ezonyango ukunyanga ukungabikho kwevithamini B, i-peripheral neuritis, kunye ne-postoperative intestinal colic. Ithatha inxaxheba kwi-metabolism yeproteni, amafutha kunye neswekile emzimbeni.
