Alfa Alpha Lipoic Acid is a pale yellow powder crystal, almost tasteless. The solubility in water is small, about 1 g/L (20°C). Soluble in 10% NaOH solution, soluble in aliphatic solvent. It is easily soluble in methanol, ethanol, chloroform and ether. Lipoic acid is also called alpha-lipoic acid. Lipoic acid has a chiral center, so it has both R and S configurations. The NATURAL lipoIC ACID IS a white CRYSTAL WITH only the R configuration, AND only the R-CONFIGURATION lipoIC acid can be covalently conjugated to a lysine residue via an amide bond to function as a coenzyme.
The synthesized lipoic acid is a mixture of R configuration and S configuration in equal proportion. It is a pale yellow powder substance, which is easily soluble in the solvent of lipids.
1. Alpha Lipoic Acid is also an antioxidant, a substance that neutralizes free radicals. What makes alpha lipoic acid unique is that it functions in water and fat.
2. Alpha Lipoic Acid converts glucose into energy.
3. Alpha Lipoic Acid is a fatty acid found naturally inside every cell in the body.
4. Alpha Lipoic Acid appears to be able to recycle antioxidants after they have been used up. Alpha lipoic acid increases the formation of glutathione.
5. Alpha Lipoic Acid is needed by the body to produce the energy for our body's normal functions.
