Phosphoglucomutase (EC 5.4. 2.2) yog ib qho enzyme uas hloov pauv pawg phosphate ntawm α-D-glucose monomer los ntawm 1 'mus rau 6' txoj haujlwm nyob rau pem hauv ntej lossis 6 'rau 1' txoj haujlwm nyob rau hauv txoj kev rov qab. Qhov tseeb dua, nws pab txhawb kev sib hloov ntawm cov piam thaj 1-phosphate thiab qabzib 6-phosphate.
Ntawm qhov no, dab tsi yog cov metabolism hauv glycogen?
Tshooj 21 Metabolism ntawm glycogen . Glycogen yog ib daim ntawv npaj tau yooj yim khaws cia ntawm cov piam thaj. Nws yog qhov loj heev, cov ceg ntoo polymer ntawm cov piam thaj seem (Daim duab 21.1) uas tuaj yeem tawg ua kom cov piam thaj hauv cov piam thaj thaum xav tau lub zog. Feem ntau ntawm cov piam thaj seem hauv cov glycogen tau txuas los ntawm s-1, 4-glycosidic bonds.
Tom qab ntawd, lo lus nug yog, Puas yog Phosphoglucomutase thim rov qab? Phosphoglucomutase (PGM) yuav hloov pauv 1- thiab 6-phosphate isomers ntawm a-D-glucose. Txawm hais tias nws yog a thim rov qab cov tshuaj tiv thaiv, tsim cov piam thaj-6-phosphate tau pom zoo.
Ib yam li ntawd, insulin tswj cov metabolism hauv glycogen li cas?
Cov tshuaj insulin stimulates lub siab kom khaws cov piam thaj hauv daim ntawv ntawm cov glycogen . Zoo sib xws, cov tshuaj insulin ua los tiv thaiv kev ua haujlwm ntawm qabzib-6-phosphatase. Cov tshuaj insulin tseem ua rau ntau qhov ntawm cov enzymes uas koom nrog ncaj qha rau synthesis ntawm glycogen , suav nrog phosphofructokinase thiab cov glycogen synthase.
Dab tsi enzyme tawg glycogen?
Thaum nws xav tau rau lub zog, glycogen tau tawg thiab hloov dua mus rau qabzib . Glycogen phosphorylase yog thawj qhov enzyme ntawm glycogen zom zaws. Rau 8-12 teev tom ntej, qabzib tau los ntawm daim siab glycogen yog lub hauv paus tseem ceeb ntawm cov ntshav qabzib siv los ntawm lub cev tas rau roj.

Dab tsi yog cov metabolism hauv qab thiab nws cuam tshuam nrog calories li cas?
Basal Metabolic Rate yog tus naj npawb ntawm cov calories uas yuav tsum tau ua kom koj lub cev ua haujlwm ntawm so. BMR tseem paub tias yog koj lub cev metabolism; yog li ntawd, txhua qhov nce rau koj qhov hnyav hnyav, xws li kev tawm dag zog, yuav nce koj li BMR. Txhawm rau kom tau txais koj li BMR, tsuas yog nkag siab koj qhov siab, poj niam txiv neej, hnub nyoog thiab qhov hnyav hauv qab no
Cov tshuaj twg qhia txog kev tawg ntawm glycogen hauv lub siab ua rau cov piam thaj hauv cov ntshav?
Glucagon ua rau lub siab hloov pauv glycogen khaws cia rau hauv cov piam thaj, uas tau tso tawm rau hauv cov hlab ntshav. Cov ntshav qab zib ntau ntau, ntawm qhov tod tes, txhawb kev tso tawm cov tshuaj insulin. Cov tshuaj insulin tso cai rau siv cov piam thaj thiab siv los ntawm cov ntaub so ntswg-insulin
Yam dab tsi tuaj yeem cuam tshuam cov tshuaj metabolism hauv cov neeg laus?
Cov no suav nrog kev hloov pauv loj hauv lub cev muaj pes tsawg leeg thiab txo qis hauv lub raum ua haujlwm, ob qho tib si tuaj yeem cuam tshuam rau cov tshuaj pharmacokinetics thiab pharmacodynamics ntawm cov tshuaj siv hauv cov neeg laus (1,2).

Dab tsi yog cov teeb meem ntawm cov metabolism hauv carbohydrate?
Cov teeb meem ntawm carbohydrate metabolism tshwm sim hauv ntau hom. Cov kev mob tshwm sim feem ntau tau txais. Tau txais los yog theem nrab derangements hauv carbohydrate metabolism, xws li ntshav qab zib ketoacidosis, hyperosmolar coma, thiab hypoglycemia, tag nrho cov cuam tshuam rau hauv nruab nrab paj hlwb
Lub luag haujlwm ntawm tus kws saib xyuas mob plawv tsis ua haujlwm yog dab tsi hauv kev saib xyuas cov neeg mob plawv tsis ua haujlwm?
Raws li ib feem ntawm pab pawg, tus kws kho mob lub plawv tsis ua haujlwm tau zoo muab rau muab kev pabcuam rau cov neeg mob thoob plaws txoj kev mob plawv tsis ua haujlwm thiab qhov no yuav tsum muaj kev koom tes ze nrog kws saib xyuas mob hauv thaj chaw tshwj xeeb tshwj xeeb xws li chav kho mob xwm txheej ceev thiab kev kho mob dav/ saib xyuas-ntawm-tus-neeg laus
