What is alpha lipoic acid?

Alpha lipoic acid (ALA) is an organic compound containing sulfur and carbon, belonging to the dithiol class of substances. It is present in very low amounts in nature, so it needs to be obtained through artificial synthesis. It is a pale yellow powdery crystal that is almost odorless. It is soluble in alkaline solutions, aliphatic solvents, and easily soluble in organic solvents such as ethanol, chloroform, and ether. Its chemical structure includes a sulfur-containing fatty acid part and an alcohol part, which makes it both fat-soluble and water-soluble, making it highly usable in the body and transferable between a variety of biological membranes.

Alpha lipoic acid, a naturally occurring dithiol compound, plays an important role in the bioenergetic reaction of human mitochondria and is widely studied and used as a powerful antioxidant.

Chemical properties

Chiral center: Lipoic acid has a chiral center, so it exists in two configurations, R and S. Natural lipoic acid has only the R configuration and can be covalently conjugated to lysine residues through amide bonds to play the role of a coenzyme.

Redox cycle: Lipoic acid exists as a mixture of two structures, a closed-ring disulfide form and an open-chain reduced form, and these two forms are converted into each other through oxidation-reduction cycles.

What are the benefits of alpha lipoic acid?

Anti-oxidize effect

Alpha-lipoic acid can act as an antioxidant, scavenging free radicals in the body and reducing oxidative stress damage to cells. This antioxidant effect helps protect biomolecules such as cell membranes, DNA, and proteins from oxidative damage. Alpha-lipoic acid also promotes the regeneration of other antioxidants such as vitamin C and vitamin E, thereby increasing the efficiency of the entire antioxidant system.

neuroprotection

Alpha-lipoic acid can stabilize cell membrane structure and reduce neuronal damage. This is of great significance for the prevention and treatment of neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease. By reducing nerve damage and promoting neuron regeneration, alpha-lipoic acid has significant therapeutic effects on neurological diseases such as diabetic peripheral neuropathy.

Improve cognitive function

Alpha-lipoic acid can improve the energy metabolism process in the brain and provide sufficient energy support for neurons. At the same time, it can also promote the synthesis and release of neurotransmitters, helping to improve cognitive functions such as memory and attention.

Anti-inflammatory

Alpha-lipoic acid can inhibit the production and release of inflammatory mediators, thereby reducing inflammatory responses and tissue damage. This has a positive effect on the prevention and treatment of inflammatory diseases such as cardiovascular diseases, autoimmune diseases, etc.

Regulate blood lipids

Alpha-lipoic acid can promote the synthesis and secretion of high-density lipoprotein cholesterol (HDL-C) and help reduce low-density lipoprotein cholesterol (LDL-C) levels in the blood. At the same time, it can also inhibit the oxidative modification of LDL-C, reduce its deposition on the blood vessel wall and the formation of foam cells, thereby reducing the risk of atherosclerosis.

Enhance immune function

Alpha-lipoic acid also has a certain immunomodulatory effect, which can enhance the function of the immune system and improve the body's resistance.

Maintain skin health

It helps promote skin repair and regeneration, improving skin texture and color.

Antioxidant Mechanism of Alpha Lipoic Acid

Alpha lipoic acid (ALA) is a natural antioxidant that is both fat-soluble and water-soluble. Alpha lipoic acid can restore other antioxidants, such as vitamin C and vitamin E, back to their active state, thereby enhancing the overall antioxidant defense system.

Alpha lipoic acid itself has a direct ability to fight free radicals and can reduce cell damage caused by oxidative stress.

It promotes the body's own antioxidant capacity by activating nuclear factor E2-related factor 2 (NRF2). NRF2 is a key transcription factor in the intracellular response to oxidative stress, through which it can induce the expression of a series of antioxidant enzymes and detoxification proteins.

What does alpha lipoic acid have to do with immunity?

Alpha lipoic acid is a naturally occurring organosulfur compound found primarily in garlic, onions, and other vegetables. Its biological activity is primarily due to its strong antioxidant and anti-inflammatory properties. These properties make it a potential immune system booster.

Alpha lipoic acid neutralizes free radicals in the body, reducing damage to immune cells caused by oxidative stress. This helps maintain the normal function of the immune system and increases the body's resistance to infection.

Inflammation is a natural response of the immune system, but chronic inflammation can weaken immune function. By inhibiting the inflammatory response, alpha lipoic acid helps balance the immune system and prevent damage caused by excessive inflammation.

Alpha lipoic acid can promote the activation and proliferation of immune cells, increasing their ability to respond to infection. This includes increased activity of phagocytes and the promotion of lymphocyte growth and differentiation.

Alpha lipoic acid helps balance the activity of the immune system, preventing over-activation or suppression. This is important in the management of autoimmune diseases because it can reduce the immune system's attack on its own tissues.

What can alpha-lipoic acid be used for?

Medical field

Alpha-lipoic acid is a powerful antioxidant that can remove free radicals in the body and protect cells from damage caused by oxidative stress. This makes it potentially useful in the prevention and treatment of diseases associated with oxidative stress.

Due to its protective effect on the nervous system, alpha-lipoic acid is widely used in the treatment of neurological diseases such as diabetic peripheral neuropathy. It can stabilize cell membranes, reduce neuronal damage, and promote nerve repair.

Studies have shown that alpha-lipoic acid can balance blood sugar, promote glucose absorption, and lower blood sugar levels.

Health food field

As a dietary supplement, alpha-lipoic acid is often added to a variety of nutritional supplements to improve the body's antioxidant capacity and immunity. It is widely used in the development of anti-aging, health care and other products.

As consumers' demand for healthy foods increases, alpha-lipoic acid is also added to some functional foods, such as functional drinks, energy bars, etc., to meet consumers' needs for health and nutrition.

Cosmetics field

Taking advantage of its antioxidant and anti-aging properties, alpha-lipoic acid is widely used in skin care and beauty products. It can improve skin texture, reduce fine lines and wrinkles, and increase skin elasticity, thereby achieving the effect of beauty and skin care.
