Alpha Lipoic Acid Free Sample of H&Z® factory is light yellow powder, almost odorless, Alpha Lipoic Acid Free Sample easily soluble in benzene, ethanol, ethyl , chloroform and other organic solvents.Alpha Lipoic Acid Free Sample almost insoluble in water, the water solubility: 1 g/L (20 ℃) soluble in 10% NaOH solution.
Alpha Lipoic Acid Free Sample is a coenzyme found in mitochondria, similar to vitamins, which eliminates free radicals that cause accelerated aging and disease. Lipoic acid enters cells after it is absorbed through the intestinal tract in the body and has both lipid-soluble and water-soluble properties.
Alpha Lipoic Acid Free Sample/α-Lipoic Acid CAS:1077-28-7
