What Is Alpha Lipoic Acid?

ALA Alpha Lipoic Acid, also known as 1,2-dithiolane-3-pentanoic acid, is a naturally occurring antioxidant widely used in dietary supplements and medical research. Its CAS number is 1077-28-7, and its molecular formula is C8H14O2S2 with a molecular weight of 206.33 g/mol.

ALA typically appears as a pale yellow or light yellow powder with a faint characteristic odor and a slightly acidic taste. It is poorly soluble in water but dissolves well in ethanol, ether, and other organic solvents, demonstrating good chemical stability. The melting point of ALA ranges from 60-62°C, and its specific optical rotation (measured in a specific solvent) falls within -1.0° to +1.0°.

Physically, Alpha-Lipoic Acid exhibits both antioxidant and pro-oxidant properties, allowing it to neutralize free radicals and protect cells from oxidative damage. As a dual-soluble antioxidant, it works effectively in both lipid and aqueous environments, making it highly versatile. 

Dr. Lester Parker, professor of molecular cell biology at the University of California, Berkeley, is one of the world’s leading antioxidant researchers. He calls Alpha Lipoic Acid a “super antioxidant.” It is the “most versatile and most active” antioxidant of all antioxidants. It is widely used in fields such as anti-aging, blood sugar regulation, and neuroprotection.

The purity of Alpha Lipoic Acid is generally 99%. There are two forms to choose from, including Powder or Granular form.

Common sources

  • Chemical Source

The chemical source of ALA Alpha Lipoic Acid powder primarily relies on synthetic processes, and the key raw materials include:

  1. Octanoic Acid (or its derivatives)
    Octanoic acid is a saturated fatty acid that provides the main carbon backbone for synthesizing ALA. Through chemical modifications, it serves as the structural foundation for the final compound.

  2. Sulfur Compounds
    Sulfur is a critical component of ALA’s dithiolane ring. Industrial production typically uses compounds like sodium sulfide or other reactive sulfur agents.

  3. Catalysts and Reagents
    Catalysts, such as acidic or basic catalysts, and solvents like dichloromethane or methanol are often used in the reaction to speed up the process and improve yields.

The synthesis process generally involves multiple steps, such as carbon chain elongation, sulfur ring formation, and functional group modifications, ultimately producing high-purity ALA. The well-established industrial synthesis methods make it cost-effective for use in dietary supplements.

  • Fonti vegetali

While alpha lipoic acid powder is not commonly extracted directly from plants, it naturally occurs in small amounts in certain plant tissues. Examples include:

  • Spinach
  • Broccoli
  • Tomatoes

These plants contain trace amounts of ALA that contribute to their overall antioxidant properties.

  • Food Sources

In the human diet, ALA alpha lipoic acid can be found in various foods, particularly those rich in mitochondria, as ALA is naturally present in cells where energy metabolism occurs. Key food sources include:

  • Red meats, especially organ meats like liver, kidney, and heart
  • Yeast, particularly brewer’s yeast
  • Potatoes
  • Brussels sprouts

Although these foods contain alpha-lipoic acid, the amounts are relatively low, and supplementation is often required to achieve therapeutic doses.

What Does Alpha Lipoic Acid Do?

When Alpha Lipoic Acid enters the body, it demonstrates a unique property that sets it apart from many other antioxidants – water and fat-soluble. This dual solubility means it can work throughout the body and in any tissue. Imagine it as a universal key that can unlock doors in watery and fatty environments within our cells.

After absorption, ALA gets distributed throughout the body’s tissues, including the brain, as it can easily cross the blood-brain barrier. Inside cells, ALA exists in two forms that work together: the oxidized form (ALA) and the reduced form (DHLA). These forms create a powerful redox couple, meaning they can switch back and forth between states while neutralizing different free radicals. Think of it as having two other tools to handle various problems.

What makes ALA particularly fascinating is its role in cellular energy production. In the mitochondria, our cellular power plants, ALA serves as a crucial cofactor for several enzyme complexes involved in energy metabolism. It helps convert nutrients into ATP, our body’s energy currency. This is similar to having a master key that allows the start of multiple machines in a factory.

ALA also demonstrates an interesting “recycling” mechanism with other antioxidants. After use, it can regenerate other essential antioxidants like vitamin C, E, and glutathione. Imagine it as a repair technician who can fix and restore other protective systems in the body. This recycling ability makes ALA’s antioxidant effects particularly powerful and long-lasting.

The compound influences cellular function through several signaling pathways. It can activate Nrf2, a protein that triggers the production of various antioxidant enzymes, helping cells boost their natural defenses. ALA also helps regulate glucose metabolism by improving insulin sensitivity through multiple mechanisms, including enhanced glucose transport and reduced inflammation.

Another remarkable aspect of ALA’s mechanism is its metal-chelating ability. It can bind to and help remove certain heavy metals from the body, acting like a molecular magnet attracting and escorting harmful metals out of our systems.

How to Produce Alpha Lipoic Acid Powder?

  1. Selezione della materia prima: High-purity octanoic acid and sulfur sources are sourced as starting materials. All reagents meet pharmaceutical specifications (>99% purity) with testing for impurities and heavy metals.
  2. Impostazione iniziale della reazione: Chemical synthesis is initiated by introducing sulfur into the octanoic acid structure under a controlled temperature (60-70°C) and inert atmosphere.
  3. Controllo della reazione: The process is maintained with continuous monitoring via HPLC. Temperature and reaction conditions are carefully controlled to ensure proper ring formation.
  4. Ring Formation: Cyclization reaction monitored carefully. Conditions are precisely controlled to ensure dithiolane ring formation while minimizing side reactions.
  5. Isolamento del prodotto: The reaction mixture undergoes extraction and filtration. The product is concentrated under controlled conditions to prevent oxidation.
  6. Processo di purificazione: Multiple recrystallization steps are performed using appropriate solvents. Special attention is paid to removing sulfur-containing impurities.
  7. Elaborazione finale: Crystals dried under vacuum at a controlled temperature (35-40°C). Product protected from light and oxygen during processing and storage.
  8. Analisi della qualità: Testing includes HPLC purity (>98%), melting point determination, heavy metals analysis, oxidation state verification, and stability studies.

Alpha Lipoic Acid VS Lipoic Acid

When comparing Alpha Lipoic Acid (ALA, CAS: 107-53-7) and Lipoic Acid (LA, CAS: 62-46-4), it’s essential to recognize that both compounds are forms of the same sulfur-containing antioxidant, but they differ in their molecular configurations and biological functions. Alpha Lipoic Acid is biologically active with the molecular formula C8H14O2S2 and a 206.34 g/mol molecular weight. In contrast, Lipoic Acid, with the molecular formula C8H14O2S2 and a molecular weight of 206.34 g/mol, refers to its oxidized and reduced states, often used interchangeably in general discussions.

Both forms appear as yellow crystalline powders and are highly soluble in water and fat, enabling them to exert antioxidant effects in both aqueous and lipid environments. However, Alpha Lipoic Acid is often considered superior for its applications due to its ability to regenerate antioxidants for the body to use and its enhanced ability to enter the brain and neutralize free radicals, offering potential neuroprotective effects. Its unique structure allows it to function as a cofactor in mitochondrial energy metabolism, improving cellular ATP production and promoting mitochondrial health.

While effective in combating oxidative stress and promoting metabolic health, Lipoic Acid does not share the same degree of regenerative capacity as its alpha counterpart in terms of antioxidant support. Lipoic Acid primarily functions in its reduced form within mitochondria to facilitate energy production and reduce inflammation. Still, it lacks the additional bioactive properties that Alpha Lipoic Acid offers, especially for neurological health.

From a bioavailability perspective, Alpha Lipoic Acid has a significant advantage in crossing the blood-brain barrier, making it particularly beneficial for neurological conditions such as Alzheimer’s and Parkinson’s. Although effective for systemic antioxidant action, Lipoic Acid lacks this specific neurological advantage. In terms of stability, both compounds are generally stable under normal conditions, though Alpha Lipoic Acid’s reactivity in solution is more sensitive to oxidative degradation when compared to Lipoic Acid.

In conclusion, Alpha Lipoic Acid and Lipoic Acid share similar antioxidant properties. Alpha Lipoic Acid offers superior therapeutic value due to its enhanced bioavailability and broader biological benefits, particularly in supporting neurological health and mitochondrial function.
