Physical Properties

Product Name: Phosphatidylserine (PS), also named L-α Phosphatidyl-L-serine
Phosphatidylserine (PS) is white or light yellow loose powder, dispersed in water. Insoluble in ethanol and methanol; soluble in chloroform, ether and petroleum ether.Phosphatidylserine (PS) is composed of three parts: the hydrophilic glycerin skeleton is the head, and the two long hydrocarbon chain lipophilic groups are the tail. The head is composed of three groups: the serine residue is combined with the phosphate residue and then connected to the hydroxyl group of C-3 glycerol; the other two hydroxyl groups of glycerol are esterified with fatty acids to form the tail. Compared with the C-1 fatty acid, the fatty acid at the C-2 position of glycerol generally has a longer carbon chain and more unsaturated bonds. Phosphatidylserine (PS) refers to a group of compounds, rather than a single component. This is due to the fact that the product lipid acetyl residues extracted from raw materials from different sources vary greatly.
Phosphatidylserine (PS) is a phospholipid that derived from the soy beans and sunflower. Phosphatidylserine (PS) contains amino acid derivative compound that is fat-soluble and found in the brain, where it contributes to cognitive functioning.Phosphatidylserine plays a key role in cell to cell communication in the brain, including the transfer of biochemical messages into the cell, triggering cellular responses. nervous system and to healthy cognitive function.
