Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic). As such, phospholipids are amphipathic. ... Another type of lipid is wax. Waxes are esters made of long-chain alcohol and a fatty acid.
Is arachidic acid good for skin?

What is Cephalin made of?
In the chemical sense, cephalin is phosphatidyl-ethanolamine. Like Lecithin, it consists of a combination of glycerol esterified with two fatty acids and phosphoric acid. Whereas the phosphate group is combined with choline in Lecithin, it is combined with the ethanolamine in Cephalin.
What is COX 1 and cox2?
The cyclooxygenase isoenzymes, COX-1 and COX-2, catalyze the formation of prostaglandins, thromboxane, and levuloglandins. The prostaglandins are autocoid mediators that affect virtually all known physiological and pathological processes via their reversible interaction with G-protein coupled membrane receptors.
