I-Glycogen i-carbohydrate eyinkimbinkimbi equkethe iimluleksi ze-glucose ezixhunywe ngethungelwano.
I-synthetic ye-glycogen (glycogenesis) iyenzeka ngaphakathi kweeyure ezingama-1-2 emva kokungeniswa kokutya kwe-carbohydrate. I-synthesisly intensive glycogen yenzeka kwisibindi. Ukongeza, i-glycogen ihlanganiswa kwimisipha yamathambo.
Elinye i-molecule ye-glycogen iquka i-residues yezigidi ze-glucose. Le nyaniso ibonisa ukuba umzimba uchitha amandla amaninzi kwimveliso ye-glycogen.
Ukutshabalalisa i-glycogen
Ukuqhekeka kwe-glycogen (glycogenolysis) kwenzeka ngexesha lokutya. Ngeli xesha, isibindi sifaka i-glycogen kuyo ngezinga elithile, elivumela umzimba ukuba ugcine i-glucose egazini ngezinga elingatshintshiyo.
Indima ye-biology ye glycogen
I-glucose yindlela ebonakalayo yamandla emzimbeni, exhasa imisebenzi yayo eyintloko. Isibindi sigcina i-glucose ngendlela ye-glycogen, kungekhona kakhulu kwiimfuno zayo, ukunikezela kwe-glucose kwezinye iishubhu-ikakhulukazi iiseli zegazi ezibomvu kunye nengqondo.
Njengoko kuchazwe ngentla, iiseli zeemfuyo, njengeeseli zesibindi, nazo ziyakwazi ukuguqula i-glucose ibe yi-glycogen. Nangona kunjalo, i-glycogen, equkethwe kwiimisipha, isetyenziswe kuphela kwimisebenzi ye-muscle. Ngamanye amazwi, i-glycogen kwiimisipha ihlala ingumthombo we-glucose kuphela kwiseli ngokwayo, ngelixa i-glycogen igcinwe kwisibindi, emva kokuqhutyelwa kwi-glucose, isetyenziswe kwisondlo senyama yonke, kwaye kubaluleke kakhulu ukugcina ingxube yeglucose efanelekileyo egazini.
I-synthesis kunye nokuchithwa kwe-glycogen
I-synthesis kunye nokuchithwa kwe-glycogen zilawulwa yinkqubo yeentlanzi kunye namahomoni. Ezi ziinkqubo ezimbini ezizimeleyo ezenzeka ngeendlela ezahlukeneyo. Njengoko sele sibonile, indima ephambili ye-glycogen ngumgaqo wokuxinwa kwe-glucose egazini, kunye nokudalwa kweso sikhokhelo se-glucose, nto leyo eyimfuneko yokwenza umsebenzi omkhulu we-muscular.
