Malic acid, an alpha-hydroxy organic acid, is sometimes referred to as a fruit acid. This is because malic acid is found in apples and other fruits. It is also found in plants and animals, including humans. In fact, malic acid, in the form of its anion malate, is a key intermediate in the major biochemical energy-producing cycle in cells known as the citric acid or Krebs cycle located in the cells' mitochondria. Malic acid, also known as apple acid, hydroxybutanedioic acid and hydroxysuccinic acid, is a chiral molecule. The naturally occurring stereoisomer is the L-form. The L-form is also the biologically active one. There is some preliminary evidence that malic acid, in combination with magnesium, may be helpful for some with fibromyalgia. Malic Acid has an oxygen sparing effect and there are a number of indications that malic acid is very critical molecule in controlling mitochonddrial function. Malate is a source of energy from the Krebs cycle and is the only metabolite of the cycle which falls in concentration during exhaustive physical activity. Depletion of malate has also been linked to physical exhaustion. By giving malic acid and magnesium as dietary supplements, flexibility to use aerobic and anaerobic energy sources can be enhanced and energy production can be boosted. Malic Acid ma$15.00 Search for:
