General description

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.
1,2-dihexadecanoyl-sn-glycero-3-phosphocholine (DPPC) is synthesized from unsaturated phosphatidylcholine (PC) by direct de novo synthesis via α1,2-dipalmitoyl diacylglycerol intermediate. The enzyme cholinephosphotransferase catalyzes the conversion of 1,2-dipalmitoyl diacylglycerol to DPPC. Synthesis of DPPC also occurs via remodeling pathway involving deacylation of unsaturated PC.


16:0 PC (DPPC) has been used in the generation of thymoquinone (TQ) liposomes, gold nanorods and calcium chloride encapsulated liposomes and bilayers for biophysical studies.

Biochem/physiol Actions

1,2-dihexadecanoyl-sn-glycero-3-phosphocholine (DPPC) is a surfactant and reduces surface tension. It is used in combination with 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) for lipid bilayer generation. DPPC alone and in combination with other phospholipid is effective in drug encapsulation and delivery.

Interactions of calcium (Ca2+) and zinc (Zn2+) cations with biomimetic membranes made of dipalmitoylphosphatidylcholine (DPPC) were studied by small angle neutron diffraction (SAND). Experiments show that the structure of these lipid bilayers is differentially affected by the two divalent cations....

The emergence of antibiotic-resistant bacterial strains has fostered fundamental research to develop alternative antimicrobial strategies. Among the several systems proposed so far, the association complexes (nanoplexes) formed by transcription factor decoys (TFDs), i.e., short oligonucleotides targeting a crucial bacterial transcription...
