General description

18:3 (cis) PC or 1,2-dilinolenoyl-sn-glycero-3-phosphocholine is an unsaturated glycerophospholipid, with substitution of two chains of linolenic acid at sn-1 and sn-2 positions of the glycerol backbone, along with choline as a headgroup.

The list of Phosphatidylcholine products offered by Avanti is designed to provide compounds having a variety of physical properties. Products available include short chain (C3-C8 are water soluble and hygroscopic), saturated, multi-unsaturated and mixed acid PC′s. All of the products are purified by HPLC, and special precautions are taken to protect the products for oxidization and hydrolysis.


18:3 (cis) PC or 1,2-dilinolenoyl-sn-glycero-3-phosphocholine:
• might be used in aqueous lipid-trehalose formulations to assess the long-term storage stability of lyophilized liposomes
• might be used in phospholipid monolayer to study the instability of unsaturated phospholipids at specified conditions
• has been used in aqueous sugar formulations or liposome formulations to characterize its degradation during lyophilization
