Aldolase B yog lub luag haujlwm rau theem thib ob hauv metabolism fructose, uas rhuav tshem cov molecule fructose-1-phosphate rau glyceraldehyde thiab dihydroxyacetone phosphate. Rau qhov tsawg dua, aldolase B tseem koom nrog hauv kev ua kom cov piam thaj yooj yim.

Raws li, qhov ua haujlwm ntawm aldolase yog dab tsi?

Aldolase yog glycolytic enzyme uas catalyzes hloov dua siab tshiab ntawm fructose 1-6-diphosphate rau glyceraldehyde 3-phosphate thiab dihydroxy-acetone phosphate ntawm glycolysis metabolic txoj kev. Hauv cell, aldolase ua yog nyob rau hauv ob qho tib si cytoplasm thiab nucleus.

Ib tus kuj yuav nug, qhov twg pom aldolase hauv lub cell? Aldolase yog pom hauv cytoplasm thiab nucleus ntawm hlwb . Txog tam sim no, muaj tag nrho peb aldolase ua isoenzymes nrhiav pom . Cov no yog hu ua Aldolase A, B, thiab C. Hom A yog suav tias yog hom nqaij leeg thiab tsis tu ncua pom txuas nrog cytoskeleton.

Hauv qhov no, aldolase ua dab tsi hauv glycolysis?

Aldolase yog ib qho ntawm cov enzymes koom nrog glycolysis cov , txhawm rau zom cov piam thaj rau hauv lub zog. Nws tshwm sim raws li qib 4 hauv glycolysis cov , rhuav tshem fructose 1, 6-biphosphate rau hauv dihydroxyacetone phosphate thiab glyceraldehyde 3-phosphate. Muaj 6 kauj ruam hauv cov txheej txheem tshuaj tiv thaiv: Qhib fructose khi rau lysine.

Yuav ua li cas ntau npaum li cas hereditary fructose intolerance?

Qhov tshwm sim ntawm hereditary fructose intolerance kwv yees yog 1 ntawm 20, 000 txog 30, 000 tus tib neeg txhua xyoo thoob ntiaj teb.
