:L-Malinsäure
Beschreibung:
L-Malinsäure, mit der CAS-Nummer 97-67-6, ist eine natürlich vorkommende organische Verbindung, die als Dicarbonsäure klassifiziert wird. Es handelt sich um einen farblosen, geruchlosen kristallinen Feststoff, der in Wasser löslich ist und einen leicht säuerlichen Geschmack hat, der häufig in verschiedenen Früchten, insbesondere Äpfeln, vorkommt. L-Malinsäure spielt eine entscheidende Rolle im Krebs-Zyklus, einem wichtigen Stoffwechselweg zur Energieproduktion in lebenden Organismen. Seine chemische Formel ist C4H6O5, und es weist zwei Carboxylgruppen (-COOH) auf, die zu seiner Säure und Reaktivität beitragen. L-Malinsäure wird in der Lebensmittelindustrie als Aromastoff und Säuerungsmittel verwendet, um den Geschmack von Getränken und Süßigkeiten zu verbessern. Darüber hinaus hat es Anwendungen in der Kosmetik- und Pharmaindustrie aufgrund seiner Fähigkeit, als pH-Regulator und Chelatbildner zu wirken. Die Verbindung wird allgemein als sicher (GRAS) anerkannt, wenn sie in Lebensmittelprodukten verwendet wird, und ihre biologisch abbaubare Natur macht sie zu einer umweltfreundlichen Option in verschiedenen Anwendungen.

CAS:(S)-Malic acid (Standard) is the standard substance of (S)-Malic acid, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. (S)-Malic acid ((S)-2-Hydroxysuccinic acid) is a tart-tasting organic dicarboxylic acid that plays a role in many sour or tart foods. Apples contain malic acid, which contributes to the sourness of a green apple. Malic acid can make a wine taste tart, although the amount decreases with increasing fruit ripeness. (wikipedia). In its ionized form malic acid is called malate. Malate is an intermediate of the TCA cycle along with fumarate. It can also be formed from pyruvate as one of the anaplerotic reactions. In humans, malic acid is both derived from food sources and synthesized in the body through the citric acid cycle or Krebs cycle which takes place in the mitochondria. Malate's importance to the production of energy in the body during both aerobic and anaerobic conditions is well established. Under aerobic conditions, the oxidation of malate to oxaloacetate provides reducing equivalents to the mitochondria through the malate-aspartate redox shuttle. During anaerobic conditions, where a buildup of excess of reducing equivalents inhibits glycolysis, malic acid's simultaneous reduction to succinate and oxidation to oxaloacetate is capable of removing the accumulating reducing equivalents. This allows malic acid to reverse hypoxia's inhibition of glycolysis and energy production. In studies on rats it has been found that only tissue malate is depleted following exhaustive physical activity. Other key metabolites from the citric acid cycle needed for energy production were found to be unchanged. Because of this, a deficiency of malic acid has been hypothesized to be a major cause of physical exhaustion. Notably, the administration of malic acid to rats has been shown to elevate mitochondrial malate and increase mitochondrial respiration and energy production.Formel:C4H6O5Molekulargewicht:134.09L-(-)-Malic acid

CAS:L-malic acid is a naturally occurring organic compound that can be found in many fruits and vegetables. It is an important intermediate in the citric acid cycle as well as a key component of the Krebs cycle. L-malic acid has been shown to have antiseizure and anti-inflammatory effects, and also inhibits the growth of bacteria such as Staphylococcus aureus. L-malic acid is synthesized from sodium carbonate and lactic acid by reacting with a mineral acid such as hydrochloric, sulfuric, or nitric acid. This reaction produces hydrogen gas, water, and l-malic acid. L-Malic Acid is also used for production of monoclonal antibodies against various targets, including human cells.
