'Ibhanki yamandla' yomzimba wethu: Masifunde nje ngeGlycogen

Ngaba wakha wazibuza ukuba imizimba yethu ifumana njani amandla ewadingayo xa singatyi okwethutyana, okanye xa sizilolonga nzima? Njengokuba sigcina ibhanki yamandla kwifowuni yethu ukuze siyisebenzise xa ibhetri iphela, imizimba yethu ikwanawo amandla esiwagcinayo esinokuwasebenzisa xa kukho imeko engxamisekileyo. Yiloo nto siyibiza ngokuba yi-glycogen ngokwezonyango. Le yinxalenye ebaluleke kakhulu yokulawula amandla emizimba yethu.

Ngokulula nje, yintoni i-glycogen?

Ngamafutshane, i-glycogen luhlobo lwe -glucose egcinwe emizimbeni yethu. Ngoku usenokuba uzibuza ukuba yintoni i-glucose. I-glucose luhlobo lweswekile . Umzimba wethu ufumana i-glucose ekutyeni esikutyayo, ingakumbi ukutya okunee -carbohydrate ( istatshi ) (njengerayisi, isonka, iitapile). Le glucose yeyona fuel iphambili enika amandla kwiiseli emizimbeni yethu.

Khawuthelekelele, emva kokutya, igazi lethu lineglucose engaphezulu kunaleyo liyifunayo. Ngoko ke umzimba wenza ntoni? Uthatha le glucose ingaphezulu uze uyigcine kwiphakheji engasetyenziswa kamva. Loo phakheji inkulu, eyenziwe ngamawaka eemolekyuli zeglucose ezidityaniswe kunye, ibizwa ngokuba yiglycogen.

Le nkqubo yenzeka ngeendlela ezimbini:

1. I-Glycogenesis: Inkqubo yokuthatha i-glucose engaphezulu egazini uze uyigcine njenge-glycogen.

2. I-Glycogenolysis : Xa umzimba wethu ufuna amandla, uyaphula i-glycogen egciniweyo, uyiguqulele kwi-glucose, uze uyikhuphele egazini.

Kungenxa yokuba ezi nkqubo zimbini zenzeka kanye kanye apho umzimba wethu ufumana amandla xa uwadinga kwaye ukhuselwe ekonyukeni okungeyomfuneko kwamanqanaba eswekile egazini.

Iphi le ndawo yokugcina amandla?

I-Glycogen igcinwa ikakhulu kwimisipha yesibindi kunye nemisipha yamathambo , kwaye inani elincinci ligcinwa engqondweni nakwezinye izicubu.

Cinga ngale ndlela, isibindi sinokugcina ipesenti ephezulu ye-glycogen xa kuthelekiswa nobukhulu bayo. Kodwa ngenxa yokuba sinezihlunu ezininzi emizimbeni yethu, uninzi (malunga nesithathu kwisine) se-glycogen iyonke lugcinwa kwimisipha.

Ubungakanani be-glycogen egcinwe emzimbeni wakho buxhomekeke kwizinto ezininzi:

• Ubungakanani beecarbohydrate ozityayo.
• Uzilolonga kangakanani kwaye unamandla kangakanani.
• Ixesha eliphakathi kokutya.
• Umsebenzi wee-enzyme zesibindi.

Le nkqubo yokugcina, ebizwa ngokuba yi-glycogenesis, ilawulwa yi-hormone ebizwa ngokuba yi-insulin . Xa sisitya, amanqanaba ethu eglucose egazini ayanyuka. Emva koko, i-pancreas yethu ivelisa i-insulin, enika iiseli zethu imiqondiso yokugcina iglucose egqithisileyo njenge-glycogen.

I-Glycogen, i-glucose, kunye ne-glucagon - yintoni umahluko phakathi kwezi zinto zintathu?

Nangona la magama mathathu evakala efana, imisebenzi yawo yahlukile. Ukuze uwuqonde kakuhle lo mahluko, jonga itheyibhile engasezantsi.

Kukho umahluko omncinci kwindlela i-glycogen eqhekeka ngayo esibindini nakwimisipha. Isibindi siyaphula i-glycogen ukuze senze i-glucose ukuze umzimba wonke uyisebenzise. Kodwa i-glucose eyenziwa yi-glycogen yemisipha inokusetyenziswa kuphela zezo zihlunu . Isizathu soku kukuba izihlunu zifuna amandla amaninzi ngexesha lokuzilolonga. Ukuba zitsala i-glucose egazini emzimbeni wonke, amalungu abalulekileyo anje ngengqondo akayi kuba ne-glucose eyaneleyo. Ngoko ke izihlunu zigcina iindawo zazo zokugcina amandla.

Ndingakwazi ukujonga amanqanaba am e-glycogen?

Enyanisweni, ukulinganisa amanqanaba e-glycogen ngokuthe ngqo kunzima kancinci kwaye akuyonto idla ngokwenziwa. Kuba eli nqanaba litshintsha rhoqo imini yonke kuxhomekeke kwinto esiyityayo nesiyiselayo kunye nokuba siwenza kangakanani umthambo. Kwiimeko ezikhethekileyo, ukuba kuyimfuneko, ugqirha unokuthatha iqhekeza elincinci lesicwili kwisibindi okanye kwimisipha aze alihlole (oku kubizwa ngokuba yi- biopsy ) ukujonga amanqanaba e-glycogen.

Kodwa ngokwesiqhelo, oogqirha benza uvavanyo olulula ukuze babone ukuba kukho ingxaki enxulumene neglucose.

• Uvavanyo lwegazi ukujonga amanqanaba eglucose egazini kunye nokusebenza kwesibindi kunye nemisipha.
• Iskeni yesibindi nge-ultrasound ukujonga ukuba asikho na isibindi esikhulu.
• Uvavanyo lwemfuza lwenziwa ukuba kukho ukurhanelwa kwesifo esizuzwe njengelifa.

Ngokomndilili, umntu omdala osempilweni une-glycogen emalunga ne-600 grams egcinwe emzimbeni wakhe. Oku kunokwahluka ngokuxhomekeke kubukhulu bomzimba womntu, ukutya, kunye nenqanaba lokuzilolonga.

Izifo ezinxulumene neGlycogen

Isifo Sokugcinwa KweGlycogen (GSD) sisifo esingaqhelekanga, esizuzwe njengelifa esithintela amandla okuvelisa okanye ukuqhekeza i-glycogen. Sibangelwa sisiphene semfuza. Senzeka xa umzimba ungenazo ii-enzymes ezifunekayo kwi-metabolism ye-glycogen.

Oku kunokukhokelela ekuqokeleleni okuyingozi kwe-glycogen kwizitho ezifana nesibindi, okanye kwabanye abantu, umzimba awukwazi ukwenza i-glycogen kwaphela. Oku kunokukhokelela kwiimpawu ezahlukeneyo, ezinje ngobuthathaka bemisipha.

Nangona kungekho nyango lwe-GSD, unyango lunokulawula iimpawu. Kukho unyango lokutshintsha ii-enzyme kwezinye iintlobo kunye nonyango lwe-cornstarch kwiintlobo ezininzi.

Ukuba unenkxalabo malunga namanqanaba eswekile egazini lakho, ukungabikho kwamandla, okanye ukuqaqamba rhoqo kwemisipha, qiniseka ukuba uthetha nogqirha wakho ngayo loo nto.Thetha nogqirha wakho. Kubaluleke ngakumbi ukufumana ingcebiso echanekileyo yezonyango kunokukhangela ulwazi kwi-intanethi.
