I-Creatine
Intshayelelo
I-Creatine, ekwaziwa ngokuba yi-α-methylmethyl acetic acid, sisondlo sendalo esikhoyo emzimbeni womntu. Ingadalwa kwi-arginine, i-glycine kunye ne-methionine kwisibindi, kwizintso nakwi-pancreas: phantsi kwe-catalysis ye-renal arginine glycine trans-benzyme, iqela le-benzyl le-arginine lidluliselwa kwi-glycine. Kwiqela le-amino, kuveliswa i-acetic acid. Emva koko isibindi sishukunyiswa yi-methyltransferase ye-acetic acid, kwaye i-methyl ye-S-adenosine methionine idluliselwa kwi-acetic acid ukuvelisa i-creatine.
Iimpawu zekhemikhali
Iikristale zePrismatic. Iqondo lokunyibilika yi-303℃ kwaye uxinano oluhambelanayo yi-1.33. Iyanyibilika emanzini abilayo kunye ne-98% ye-acetic acid, inyibilika kancinci kwi-ethanol, ayinyibiliki kwi-ether kunye ne-butyric acid.Ikwisisombululo samanzi, sifunyanwa nge-mercury acetate kubushushu begumbi ukuze kufunyanwe i-methyl acethyde, kwaye ekugqibeleni kwenziwa i-methylamine kunye ne-oxalic acid.
SEBENZISA
I-Creatine inemisebenzi esisiseko yokwandisa umthamo wamanzi kwiiseli zemisipha, ukunceda iiseli zemisipha ukugcina amandla, kunye nokwandisa ukwenziwa kweproteni. Phakathi kwazo, i-creatine eyenziwe ngokwenziwa ingasetyenziselwa ukukhuthaza ukulungelelaniswa kwemisipha yamathambo ukuze ikwazi ukwenza umthambo onzima kunye nokulwa nokudinwa kwabantu ababuthathaka. Ingasetyenziselwa nokulungiselela amayeza okunyanga isifo sentliziyo kunye nokungakwazi ukuphefumla; ukulungiselela amalungiselelo amayeza aqulethe i-hormone yokukhula komntu; kwaye ingasetyenziselwa ukuhlanganisa ukutya okutsha okunempilo, okunefuthe lokulwa nokwaluphala kunye nokuchacha emzimbeni.
