Acido L-malico

Descrizione:

Acido L-malico, con il numero CAS 97-67-6, è un composto organico che si trova naturalmente ed è classificato come un acido dicarbossilico. È un solido cristallino incolore e inodore, solubile in acqua e ha un sapore leggermente acidulo, comunemente trovato in vari frutti, in particolare nelle mele. Acido L-malico gioca un ruolo cruciale nel ciclo di Krebs, una via metabolica chiave per la produzione di energia negli organismi viventi. La sua formula molecolare è C4H6O5 e presenta due gruppi funzionali carbossilici (-COOH), che contribuiscono alla sua acidità e reattività. Acido L-malico è utilizzato nell'industria alimentare come agente aromatizzante e acidificante, migliorando il sapore di bevande e caramelle. Inoltre, ha applicazioni nelle industrie cosmetiche e farmaceutiche grazie alla sua capacità di agire come regolatore di pH e agente chelante. Il composto è generalmente riconosciuto come sicuro (GRAS) quando utilizzato in prodotti alimentari, e la sua natura biodegradabile lo rende un'opzione ecologicamente sostenibile in varie applicazioni.

(S)-Malic acid (Standard)

CAS: 97-67-6

(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.

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.
