Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic.The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group.The two components are joined together by a glycerol molecule. The phosphate groups can be modified with simple organic molecules such as choline.hey can form lipid bilayers because of their amphiphilic characteristic.

1 The national average cost of an abdominal CT scan is $2,325, while the national minimum cost and national maximum cost being $2,000 and $9,000 respectively.2  These are costs without any sort of health insurance policy kicking in.3  The costs are going to depend on the medical facility and geographical location. The costs of this scan include technical fees which is the cost of the procedure itself. 2  The CT scan should take about an hour. 3  While the test itself only lasts a few minutes, the prep work and time it takes to finish everything up will take a little longer.
According to a 2008 study conducted by the American Hospital Directory, average CT scans cost around $250 to $275, with the total charge coming to about $1,750 (the difference being covered by insurance or similar programs). This does not mean every hospital will charge these amounts.
