Phosphatidylcholine (PC)

BOC Sciences has a specialized liposome technology platform dedicated to providing the most complete solution for liposome drug development services for the pharmaceutical/biotechnology, cosmetic, and nutritional supplement industries. We provide high-quality phosphatidylcholine.

Introduction of PC

Phosphatidylcholine (PC) is an amphiphilic molecule consisting of a hydrophilic head and a hydrophobic tail.

Natural PC

• PC is extracted from egg yolk, soybean, bovine heart and spinal cord.
• Each PC has aliphatic chains of different lengths and degrees of saturation. Plant-based PC has a highly unsaturated aliphatic chain, while animal-based PC has a mostly saturated aliphatic chain.

Synthesized PC

• Dipalmitoylphosphatidylcholine (DPPC)
• Distearoylphosphatidylcholine (DSPC)
• Dimyristoylphosphatidylcholine(DMPC)

Physicochemical Properties of PC

Under normal conditions, pure PC is a white solid, which is easy to absorb water, so it is mostly transparent or translucent and has a light fragrance. PC is soluble in organic solvents, such as n-hexane, diethyl ether, ethanol, methanol, etc. It is also soluble in water, forming a colloidal solution, insoluble in acetone, and has no definite melting point. In the presence of phospholipase A1, PC can produce lysophosphatidylcholine (LPC) with enhanced emulsifying ability.

Functions of PC

• One of the important components of cell membranes
• An important structural component of plasma lipoproteins and bile
• A neurotransmitter related to nerve excitation and conduction
• Closely related to fat metabolism
• Anti-atherosclerosis, lowering blood cholesterol, total esters and liver protection (prevention of fatty liver)

Applications for PC

• Liposomes
• Pharmaceutical emulsifiers
• Supplementary materials for pharmaceuticals
• Dietary supplement
• Beauty products
