Phosphatidylcholine (PC) is extracted from soybean powdered lecithin,the product is yellow or brown yellow wax,which is easy to absorb moisture and oxidize,it is also easy for them to disperse in water and form stable emulsion,they are insoluble in acetone,but soluble in alcohol,ether,hexane and other organic solvents. Phosphatidylcholine is a vital substance found in every cell of the human body. Thus, some researchers have used mutant mouse models with severe oxidative damage as a model of "accelerated aging" to investigate the possible role of phosphatidylcholine supplementation as a way of slowing down aging-related processes and improving brain functioning and memory capacity in dementia. |
