What is Alpha Lipoic Powder? Lipoic acid, also known as alpha lipoic (α-LA), with the molecular formula C8H14O2S2, is a pale yellow powdery crystal, almost odorless. Solubility in water is small, about 1 g/L (20℃). Soluble in 10% NaOH solution, soluble in aliphatic solvents. Soluble in methanol, ethanol, chloroform, and ether. Lipoic acid has a chiral centre and therefore has both R and S configurations. Natural lipoic acid is a white crystal with only the R configuration, and only the R configuration of lipoic acid can covalently affix to lysine residues through amide bonds to function as a coenzyme. Synthetic lipoic acid, on the other hand, is a mixture of equal proportions of the R and S configurations and is a yellowish powder that is highly soluble in lipid-based solvents. Green Spring Technology supplies Alpha Lipoic Powder Bulk with high purity, no impurities, no solvent residue, and no pesticide residue. Green Spring Technology has been focusing on the ...
