MMA is a four-carbon molecule that is a product of the metabolic break-down of valine, isoleucine, and propionic acid. 1 Vitamin B12 is a critical cofactor for the conversion of MMA to succinate. 1 As a result, vitamin B 12 deficiency causes an accumulation of MMA in the serum. 1 MMA concentrations will often become elevated in the early stages of vitamin B 12 while serum vitamin B 12 levels

Chronic administration of methylmalonate on young rats alters neuroinflammatory markers and spatial memory Immunobiology . 2013 Sep;218(9):1175-83. doi: 10.1016/j.imbio.2013.04.008.

Cell death was attenuated in a medium containing antioxidants. Further characterization revealed that DNA laddering could be detected after 3 h of treatment. A blood test to detect high levels of MMA is a decisive test for MMA. It may also be detected via a urine test for abnormally high levels of the chemical methylmalonate. Prenatally, MMA may be diagnosed by measuring the activity of the apoenzyme methylmalonyl-CoA mutase in cultured cells grown from the cells obtained during an amniocentesis . Methylmalonate (MMA, Isosuccinic Acid, NSC 25201) is a dicarboxylic acid that can be derived from methylmalonyl-coenzyme A (methylmalonyl-CoA).

This child had 3-hydroxyisobutyric aciduria, and finally MMA (in blood or urine specimens) can be measured using high performance sensitivities of serum cobalamin, methylmalonic acid, and total homocysteine 1 Oct 2020 Although higher cumulative exposure to mutagens, reduction of immune efficiency, and greater numbers of cell divisions with age are partially Patients with elevated baseline levels of tHcy alone, or of both tHcy and. MMA, were found to have a high risk of severe toxicity that led us to postulate that At the time of diagnosis urinary methylmalonate had risen to 4280. µmol/mmol see levels of methylmalonic acid:creatinine ratios as high as 4890 μmol/l in This deficiency is caused by mutations in the MUT gene (6p21). Diagnostic methods. Diagnosis is based on the finding of increased methylmalonic acid in blood Our MyB12 vitamin B12 blood test.

Methylmalonate (10 mM) caused >90% mortality of neurons although cortical cells were unexpectedly more vulnerable. Cell death was attenuated in a medium containing antioxidants. Further characterization revealed that DNA laddering could be detected after 3 h of treatment.

Methylmalonic acid (MMA) is a substance produced in very small amounts and is necessary for human metabolism and energy production. In one step of metabolism, vitamin B12 promotes the conversion of methylmalonyl CoA (a form of MMA) to succinyl Coenzyme A. 2003-07-01 Methylmalonic acid is a dicarboxylic acid that is malonic acid in which one of the methylene hydrogens is substituted by a methyl group.

Excessive sodium can cause an unhealthy amount of fluid retention and may result in high blood pressure. Both of these issues could result in high creatinine levels. Maintain a low-sodium diet. Stay away from salty foods and drinks, and opt for low-sodium versions of common food products (canned soup, bottled sauces, etc.) when available.

Excretion of methylmalonate is not affected by folic acid, vitamin E, or selenium, but is markedly decreased by small amounts of vitamin B(12) added to the diet.

When low results are discovered, the most common recommendation is to increase the amount of green, leafy vegetables that are being added. 2021-01-19 · High Methylmalonic Acid Causes. Causes of high MMA include: B12 deficiency, most often due to a B12-poor diet, issues with nutrient absorption, or drugs that deplete B12 levels (e.g.

When low results are discovered, the most common recommendation is to increase the amount of green, leafy vegetables that are being added. Beans, fruit, and other vegetables are also highly recommended on a regular basis. Methylmalonic Acid (MMA) Test: Normal & High Levels Methylmalonic acid (MMA) is normally made in the body in tiny amounts. It builds up only in the absence of vitamin B12 and can be used as a functional indicator of vitamin B12 status. However, testing MMA is still controversial and has some limitations.
