I-Glucose-6-Phosphate Dehydrogenase CAS:9001-40-5

I-Cellular Metabolism: I-G6PD ibandakanyeka kwindlela ye-glucose metabolism, ngakumbi indlela ye-pentose phosphate. Ikhuthaza ukuguqulwa kwe-glucose-6-phosphate ibe yi-6-phosphogluconolactone, ivelisa i-NADPH kule nkqubo. I-NADPH yimolekyuli ebalulekileyo kwiinkqubo ezahlukeneyo zeseli, kubandakanya ukuzikhusela kwi-antioxidant, i-biosynthesis ye-fatty acids kunye ne-cholesterol, kunye nokugcina ibhalansi ye-redox yeseli.

Ukhuselo lwe-Antioxidant: I-NADPH eveliswa yi-G6PD ibalulekile kwimveliso ye-glutathione enciphileyo (GSH), imolekyuli ebalulekileyo ye-antioxidant. I-GSH ikhusela iiseli kwi-oxidative stress ngokunciphisa ii-free radicals kunye ne-reactive oxygen species (ROS). Ukunqongophala kwe-G6PD kunokubeka emngciphekweni ukufumaneka kwe-NADPH kwaye kunciphise ukusebenza kakuhle kokhuselo lwe-antioxidant, okukhokelela ekwandeni kokuchaphazeleka kumonakalo we-oxidative.

I-Hemolytic Anemia: Ukunqongophala kwe-G6PD yeyona nto ixhaphakileyo kwihlabathi liphela. Ichaphazela kakhulu amadoda kwaye inokukhokelela kwi-hemolytic anemia, imeko ebonakaliswa kukutshatyalaliswa kweeseli ezibomvu zegazi. Izinto ezithile ezibangela oku, ezifana nosulelo, amayeza athile (umz., amayeza okulwa nemalariya, amayeza e-sulfa), kunye nokutya okuthile (umz., iimbotyi ze-fava), zinokubangela i-hemolysis kubantu abane-G6PD deficiency. Ukunqongophala kubangela ukungakwazi ukulawula uxinzelelo lwe-oxidative olubangelwa zezi zinto ezibangela oku, okubangela ukuqhekeka kweeseli ezibomvu zegazi.

I-Clinical Pharmacology: Ukuhlolwa kwe-G6PD kubalulekile kwi-clinical pharmacology ukuthintela iziphumo ezibi zamayeza. Amanye amayeza, anjenge-antimalarials ezithile (umz., i-primaquine) kunye ne-antibiotics (umz., i-sulfonamides), anokubangela i-hemolysis kubantu abane-G6PD deficiency. Ukuhlolwa kwangaphambili kwe-G6PD deficiency kunceda ekuchongeni abantu abasengozini kwaye kunokukhokela ukhetho lwamayeza okanye ukusetyenziswa kwezinye iindlela zonyango ukuthintela iziganeko ezinzima ze-hemolytic.
