General description

20:1 (Cis) PC (1,2-dieicosenoyl-sn-glycero-3-phosphocholine) is a lipid derivative having a phosphocholine backbone. It has two 20 carbon fatty acid chains, each having one cis double bond at the 11th carbon.
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.


20:1 (Cis) PC (1,2-dieicosenoyl-sn-glycero-3-phosphocholine) has been used in liposome preparation. It may be used as an internal standard for mass spectrometric analyses and also used in planar bilayer lipid membranes (BLMs) to study its effect on the dependence of single-channel properties of C-terminal colicin peptide (P178).

Biochem/physiol Actions

Phosphatidylcholine (PC) is involved in the fusion and transport of membranes.
