Glycogen. Waa maxay? Aan u ogaato!

Glycogen waa adag ah, carbohydrate ah oo adag, taas oo la aasaasay in geeddi-socodka of glucose glycogenesis wada daama cunto. Laga soo bilaabo barta kiimikada ee aragtida la go'aamiyo by C6H10O5 formula iyo wakiil ka polysaccharide Kolloidol isagoo silsilad heer sare ah jahaysteen ku harta glucose. In this article, waxaan sheegi doonaa dhammaan ku saabsan glycogen ah: waxa ay tahay, waxa ay tahay hawsha ay yihiin, halkaas oo ay kor u kaydsato. Sidoo kale, waxaan ku tilmaami doonaa waxa ay tahay leexashooyinkaasi ee geedi socodka of synthesizing.

Glycogen: waxa uu yahay iyo sida ay ku dhexsameeysmo jirka?

Glycogen waa jirku u baahan yahay kaydka glucose. In aadanuhu waxa uu ku dhexsameeysmo sida soo socota. carbohydrates cuntada (oo ay ku jiraan noqde iyo disaccharides - lactose, maltose iyo sucrose) hoos tallaabada of enzyme (amylase) waxaa loo kala qaybiyey taagoo yar. Markaas, ee falgalka xiidmaha yar-yar sida sucrase, maltase iyo amylase ganaca hydrolyzing ku harta carbohydrate in monosaccharides, oo ay ku jiraan glucose. Mid ka mid ah qayb ka mid ah la sii daayo glucose, galaan dhiigga, beerka, iyo kuwa kale ee la qaado galay unugyada xubnaha kale. Si toos ah unugyada, oo ay ku jiraan muruqa, waxaa jira suuska a xiga ee glucose monosaccharide ah, oo la yidhaahdo glycolysis. In geeddi-socodka of glycolysis, taas oo dhacda leh ama aan lahayn ka qaybgalka (laylinta iyo anaerobic) oxygen yihiin dhexsameeysmo Britain ATP, kuwaas oo ah il tamar in noolaha oo dhan. Laakiin ma glucose oo dhan galo cuntada ee jidhka bini'aadamka, wada baabbi'iyey ee ereygu wuxuu ahaa ee ATP. Qayb ka mid ah waxa lagu kaydiyaa foomka of glycogen. Geedi socodka ku lug polymerization ee glycogenesis, i.e. dheer ee isku xig xiga ee glucose si kasta oo kale oo la xirrira monomers polysaccharide ah jahaysteen silsilad sarkhaansan yihiin falgalka gaar ah.

Meeday glycogen?

glycogen kaydiyaa helay qaab dhagaxyada gaar ah cytoplasm (cytosol) unugyada badan oo jidhka ah. content Gaar sare ee glycogen ee beerka iyo murqaha unugyada. Oo Murqo glycogen - il of stock glucose unugyada muruqa badan (in ay dhacdo load culus), iyo sii wadida fiirsashada gulukooska ee dhiigga ee caadiga ah, cagaarshowga. Sida sahayda oo ka mid ah carbohydrates adag laga heli karaa unugyada dareenka, wadnaha, quseyo, epithelium, nudaha connective, xuub-axaleedka of ilmo galeenka iyo unugyada uurjiifka. Sidaas daraaddeed, waxaan eegay waxa loola jeedo ereyga "glycogen" ah. Waa maxay, hadda waxaa cad. Next, aan ka hadalno ay xilkooda u gutaan.

Maxaa jirku u baahan yahay glycogen?

In glycogen jidhka waxaa loo isticmaalaa sida reserve tamarta ah. In xaaladaha degdegga ah jidhka ka bixi karin waxaa ka mid ah ka maqan glucose. Sidee tani u dhici? burburka Glycogen dhacdaa inta u dhexeysa cuntooyinka, laakiin sidoo kale si weyn u dadajinaya inta lagu jiro shaqada jirka u daran. Marxaladani waxay dhacdaa by cholesterol ku harta glucose sarkhaansan yihiin falgalka gaar ah. Sidaas darteed, glycogen decomposes in glucose xor iyo glucose-6-phosphate ee ATP oo aan kharashka.

Maxaad ugu baahan tahay glycogen ee beerka?

Beerku waa mid ka mid ah xubnaha gudaha ugu muhiimsan ee jirka aadanaha. Waxaa qabata kala duwan oo laga maarmin. Ku jiraan bixisaa heerka sonkorta dhiigga caadiga ah, waa lagama maarmaan u ah hawlaha maskaxda. The hababka ugu muhiimsan ee ay u ilaaliyaan glucose gudahood kala duwan ee caadiga ah - laga bilaabo 80 ilaa 120 mg / dL la raacay by daatay ee gluconeogenesis glycogen lipogenesis iyo Isbadal sonkor kale in sonkorta. By hoos heerka sonkorta dhiigga shidaa phosphorylase ka dibna glycogen beerka waxaa ku dhegay. From cytoplasm unugyada baaba'aan idihiisa, iyo glucose galo dhiigga, jidhka siiyo tamarta loo baahan yahay. At heer sare ah oo sonkor ah, tusaale ahaan cuntada ka dib, unugyada beerka ay bilaabaan in ay si firfircoon uga synthesize glycogen oo loo aamino. Gluconeogenesis waa geedi socod lagu synthesizing glucose laga soo gooyay beerkii in walxaha kale, oo ay ku jiraan acids amino. The sharciyeed shaqada beerka ka dhigaysa mid adag lagama maarmaanka u ah hawlaha jidhka ee caadiga ah. Weecasho - a koror / hoos u dhac weyn oo heerka sonkorta dhiigga - khatar halis ku ah caafimaadka dadka.

Ku xadgudubka Avv glycogen

cudurada dheefshiidka waa koox ka mid ah glycogen glycogen cudurada la iska dhaxlo. Sababaha ay yihiin falgalka cilladaha kala duwan toos ah ugu lug sharciyeynta formation glycogen ama cholesterol. Ka mid ah cudurada glycogen iyo glycogenoses go'doon aglikogenozy. Ka hore waa cudur dhif ah dhaxlay sababa raasamaal xad dhaaf ah polysaccharide ee unugyada C6H10O5. Avv Glycogen iyo joogitaanka xad-dhaaf ah ku xiga ee beerka, sambabada, kelyaha, murqaha lafaha iyo cilladaha wadnaha sababa enzyme (tus, glucose-6-phosphatase) oo ku lug leh burburkii of glycogen. Inta badan, marka jirkooda glycogen arkay xadgudubyada horumarinta, dhimaal psychomotor, gobolka hypoglycemic daran, ilaa bilawga kooma. Si loo xaqiijiyo cudurka iyo loo ogaado nooca glycogenosis qaadeen beerka biopsy iyo muruqyada, ka dibna soo dir wax ka dhalanaya baadhitaan histochemical. Intii uu content glycogen set ee unugyada, iyo waxqabad ee ensaymes in ay gacan ay Avv iyo nabaadguurka.

Haddii jidhka oo ka mid ah meelaha aan glycogen, maxay ka dhigan tahay?

Aglikogenozy wakiil cudur la iska dhaxlo dhab ah waxaa keeno la'aanta enzyme awood si ay u fuliyaan ereygu wuxuu ahaa ee glycogen (glycogen). In jiritaanka cudurkan ku glycogen beerka oo gebi ahaanba maqan. daliilka Clinical cudurka waa: gulukooska ee dhiigga aad u hooseeya, dheehan - qalal hypoglycemic joogto ah. Xaaladda bukaanka waxaa lagu qeexaa sida aad u halis ah. aglikogenoza Joogitaanka baaro by fulinta xinjirta beerka ah.
