Is thiamine important for DNA synthesis?

Is thiamine important for DNA synthesis?

Thses data indicate that the thiamine deficiency state interferes with the synthesis ofsome discrete DNA pool(s) in the brain. This effect may be due to thiamine deficiency per se and /or some thiamine-induced impaired food assimilation or utilization.

What are thiamine dependent enzymes?

Thiamine diphosphate-dependent enzymes play a role in photosynthesis in chloroplasts (TK, DXPS), pentose phosphate pathway (TK), and alcoholic fermentation (PDC) in cytoplasm as well as in ATP synthesis by participation in oxidative decarboxylation of pyruvate (PDH) and Krebs cycle (OGDH) in mitochondria.

How is thiamine synthesized?

Thiamin is synthesized by most prokaryotes and by eukaryotes such as yeast and plants. In all cases, the thiazole and pyrimidine moieties are synthesized in separate branches of the pathway and coupled to form thiamin phosphate. A final phosphorylation gives thiamin pyrophosphate, the active form of the cofactor.

Which of these vitamins has a methylated pyrimidine ring bonded thru a methylene linkage to a thiazole ring?

Thiamine deficiency principally damages the nervous system (dry beriberi) and the cardiovascular system (wet beriberi). The vitamin is a highly water soluble nutrient, comprising a substituted pyrimidine linked to a substituted thiazole by a methylene bridge.

Does magnesium deplete thiamine?

It can be presumed that thiamine deficiency inhibits magnesium depletion and, consequently, the influence of magnesium deficiency is less significant in the thiamine- and magnesium-deficient animals.

How does thiamine deficiency cause neurological problems?

Thiamine deficiency might cause brain tissue injury by inhibiting brain energy utilization given the critical role of thiamine-dependent enzymes associated within glucose utilization (27).

Does thiamine have side effects?

Side effects of thiamine include: warmth. severe allergic reaction (anaphylaxis) skin discoloration.

Can I take thiamine and magnesium together?

Thiamine and Magnesium Should Be Supplemented Together The same study showed a lower levels of thiamine in nerve, liver, and kidney of magnesium deficient animal, providing further support for magnesium’s role in thiamine retention.

How do you know if you are low in thiamine?

Early symptoms of thiamin deficiency are vague. They include fatigue, irritability, poor memory, loss of appetite, sleep disturbances, abdominal discomfort, and weight loss. Eventually, a severe thiamin deficiency (beriberi) may develop, characterized by nerve, heart, and brain abnormalities.

Is it safe to take thiamine supplement?

Thiamine is generally safe. Very high doses may cause stomach upset. Taking any one of the B vitamins for a long period of time can result in an imbalance of other important B vitamins. For this reason, you may want to take a B-complex vitamin, which includes all the B vitamins.
