1-Palmitoyl-2-hexadecyl-phosphatidylcholine, also known as 1-palmitoyl-2-palmitoleyl-phosphatidylcholine (PPC), is a type of phospholipid that plays a crucial role in the structure and function of cell membranes. It consists of a glycerol backbone, two fatty acid chains (palmitic acid and palmitoleic acid), a phosphate group, and a choline molecule. This amphiphilic molecule has both hydrophilic (water-loving) and hydrophobic (water-repelling) properties, allowing it to form lipid bilayers in biological membranes. PPC is involved in various cellular processes, including signal transduction, membrane transport, and cell adhesion. It is also used in pharmaceutical formulations and drug delivery systems due to its ability to stabilize and protect lipophilic compounds.
The CAS Registry Mumber 90581-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,8 and 1 respectively; the second part has 2 digits, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 90581-95: (7*9)+(6*0)+(5*5)+(4*8)+(3*1)+(2*9)+(1*5)=146 146 % 10 = 6 So 90581-95-6 is a valid CAS Registry Number.
