1,2-Dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE) is a type of phospholipid, specifically a phosphatidylethanolamine (PE) derivative, that plays a crucial role in the structure and function of cell membranes. It consists of two oleoyl chains (18 carbons each) attached to the glycerol backbone, with a phosphoethanolamine group at the sn-3 position. DOPE is known for its ability to form non-lamellar structures, such as inverted hexagonal phases, which contribute to membrane curvature and fusion. This property makes it essential in various cellular processes, including vesicle trafficking, protein sorting, and signal transduction. Additionally, DOPE is involved in the regulation of membrane fluidity and permeability, as well as in the formation of lipid rafts, which are microdomains within the membrane that serve as platforms for signaling and protein-protein interactions. Overall, DOPE is a vital component of cell membranes, contributing to their stability, function, and dynamic properties.
The CAS Registry Mumber 5683-50-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 3 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5683-50: (6*5)+(5*6)+(4*8)+(3*3)+(2*5)+(1*0)=111 111 % 10 = 1 So 5683-50-1 is a valid CAS Registry Number.
