malic acid

1. Malic acid (Pomalus acid) did reduce populations of L. monocytogenes on poultry. 2. Malic acid supplementation may be useful for conservative treatment of calcium renal stone disease by virtue of its capacity to induce these effects.

Malic acid disodium hydrate is commonly used as a food additive, buffering agent and nutritional supplement with the ability to enhance food flavor, improve texture and regulate acidity. Hydroxybutanedioic acid disodium hydrate can also be used as a dietary supplement to help increase energy production, reduce fatigue and enhance athletic performance.

(S)-Malic acid ((S)-2-Hydroxysuccinic acid) is a tart-tasting organic dicarboxylic acid found in many sour foods, such as apples, and contributes to the sourness of green apples and tartness of wine, although its concentration decreases with fruit ripeness (wikipedia). In its ionized form, it is called malate, an intermediate in the TCA cycle alongside fumarate, and can be formed from pyruvate through anaplerotic reactions. In humans, malic acid is derived from food sources and synthesized in the body via the citric acid cycle in mitochondria, playing a crucial role in energy production under both aerobic and anaerobic conditions. Under aerobic conditions, malate is oxidized to oxaloacetate, providing reducing equivalents via the malate-aspartate redox shuttle, while during anaerobic conditions, its simultaneous reduction to succinate and oxidation to oxaloacetate removes excess reducing equivalents, reversing hypoxia's inhibition of glycolysis and energy production. Studies on rats have shown that tissue malate depletes following exhaustive physical activity, suggesting that malic acid deficiency may cause physical exhaustion. Administering malic acid to rats has been shown to elevate mitochondrial malate, increasing mitochondrial respiration and energy production.

Malic acid 4-Me ester is a natural product for research related to life sciences. The catalog number is TN4487 and the CAS number is 66178-02-7.

D-(+)-Malic acid ((R)-Malic acid) is a dicarboxylic acid that is made by all living organisms. Malic acid has two stereoisomeric forms (L- and D-enantiomers). The malate anion is an intermediate in the citric acid cycle.

Coumalic acid (Cumalic Acid) can be prepared from malic acid. It can be used in the industrial production of spices, flavorings, and cosmetics. It serves as a polymer component as well as an active molecular scaffold with anti-bronchial and malarial activity.

2-Isopropylmalic acid (α-Isopropylmalate) inhibits excess reactive oxygen species (ROS) production and stress kinase activation in PM2. 5-treated dermal fibroblasts, promotes primary ciliogenesis and restores PM2. 5-induced primary ciliogenesis hypoplasia in dermal fibroblasts.

Benzoylmalic acid is a useful organic compound for research related to life sciences. The catalog number is T125309 and the CAS number is 22138-51-8.

Caffeoylmalic acid is a useful organic compound for research related to life sciences and the catalog number is T124908.

L-Tartaric acid ((2R,3R)-(+)-Tartaric acid) occurs naturally in many plants, particularly grapes and tamarinds, and is one of the main acids found in wine. It is used as an antioxidant. Salts of tartaric acid are known as tartrates. L-Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death.

rel-(2R,3S)-2,3-Dihydroxysuccinic acid hydrate (meso-Tartaric acid monohydrate) occurs naturally in many plants, particularly grapes and tamarinds, and is one of the main acids found in wine. It is used as an antioxidant. Salts of tartaric acid are known as tartrates. Tartaric acid is a muscle toxin that inhibits the production of malic acid and, in high doses, causes paralysis and death.
