I-Creatine
Isingeniso
I-Creatine, eyaziwa nangokuthi i-α-methylmethyl acetic acid, iyisakhi semvelo esikhona emzimbeni womuntu. Ingaphinde yenziwe kusukela ku-arginine, i-glycine kanye ne-methionine esibindini, ezinso kanye nakuma-pancreas: ngaphansi kwe-catalysis ye-renal arginine glycine trans-benzyme, iqembu le-benzyl le-arginine lidluliselwa ku-glycine. Eqenjini lama-amino, kukhiqizwa i-acetic acid. Ngemuva kwalokho isibindi siqhutshwa yi-methyltransferase ye-acetic acid, bese i-methyl ye-S-adenosine methionine idluliselwa ku-acetic acid ukukhiqiza i-creatine.
Izakhiwo zamakhemikhali
Amakristalu e-Prismatic. Iphuzu lokuncibilika lingu-303℃ kanti ubuningi obuhlobene bungu-1.33. Incibilika emanzini abilayo kanye ne-98% acetic acid, incibilika kancane ku-ethanol, ayincibiliki ku-ether kanye ne-butyric acid.IIsixazululo samanzi, sitholakala nge-mercury acetate ekamelweni lokushisa ukuze kutholakale i-methyl acethyde, bese ekugcineni kwakheka i-methylamine ne-oxalic acid.
SEBENZISA
I-Creatine inemisebenzi eyisisekelo yokwandisa okuqukethwe kwamanzi kwamaseli emisipha, ukusiza amaseli emisipha ukugcina amandla, nokwandisa ukwakheka kwamaprotheni. Phakathi kwayo, i-creatine eyenziwe ngokwenziwa ingasetshenziswa ukukhuthaza ukuzivumelanisa kwemisipha yamathambo nokuzivocavoca okunzima nokulwa nokukhathala kwabantu ababuthakathaka. Ingasetshenziswa futhi ukulungiselela imithi yokwelapha izifo zenhliziyo kanye nokwehluleka kokuphefumula; ukulungiselela amalungiselelo emithi aqukethe i-hormone yokukhula komuntu; futhi ingasetshenziswa ukuhlanganisa ukudla okusha okunempilo, okunomphumela wokulwa nokuguga kanye nokululama ngokomzimba.
