2-Palmitoyl-sn-glycero-3-phosphorylcholine, also known as 1,2-dihexadecanoyl-sn-glycero-3-phosphocholine or simply PC, is a type of phospholipid that plays a crucial role in the structure and function of cell membranes. It is composed of two palmitic acid chains (each containing 16 carbon atoms) attached to a glycerol backbone, with a phosphorylcholine group at the third carbon position. This amphiphilic molecule has both hydrophilic (water-loving) and hydrophobic (water-fearing) regions, allowing it to form lipid bilayers in biological membranes. PC is essential for maintaining membrane integrity, fluidity, and function, and it is involved in various cellular processes, including signal transduction and lipid transport.

6791-22-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6791-22-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6791-22:
(6*6)+(5*7)+(4*9)+(3*1)+(2*2)+(1*2)=116
116 % 10 = 6
So 6791-22-6 is a valid CAS Registry Number.

Nuclear Magnetic Resonance Evidence for Radiation Damage of Saturated Phosphatidylcholine in Bilayers

Casu, Mariano,Lai, Adolfo,Erriu, Gianni,Onnis, Salvatore,Zucca, Nazario

, p. 408 - 412 (1992)

Multilayer membranes of 1,2-dipalmitoyl-sn-glycero-3-phosphorylcholine were prepared in D2O and exposed to γ-radiation.Changes in the chemical structure due to irradiation were studied by (1)H, (13)C and (31)P NMR after lyophilization and dissolution in chloroform-methanol (1:2 v/v).One- and two-dimensional techniques were used. 1-Palmitoyl-sn-glycero-3-phosphorylcholine, 2-palmitoyl-sn-glycero-3-phosphorylcholine, glycero-3-phosphorylcholine and palmitic acid were identified as new components.Their development during irradiation was quantitatively determined.The results were discussed in terms of possible reaction steps responsible for the radiolytic decomposition. Key words: (1)H NMR, (13)C NMR, (31)P NMR, 1,2-dipalmitoyl-sn-glycero-3-phosphorylcholine, bilayer, radiation damage
