BIOL 2021 Lecture Notes - Lecture 83: Phospholipase A2, Indian Cobra, Sphingosine
Document Summary
How are they broken down: hydrolyzed into 3 fatty acids and 1 glycerol, physiologically in body: Enzyme called a lipase present in adipocytes and intestines: saponification. Treat with base (naoh) and heat to produce soaps (salts of fas) and glycerol. Used to (and still do!) boil animal fat with lye (naoh) to make soap! Chm333 lecture 22: 3/22/13 spring 2013 professor christine hrycyna: phosphoacylglycerols (phospholipids; phosphoglycerides) Very similar in structure to triacylglycerols except one of the alcohols of glycerol is esterified by phosphoric acid instead of a fatty acid = phosphatidic acid (pa) The phosphoric acid group is then esterified by a second alcohol to form the phosphoacylglycerol. These alcohols give very different properties to the phospholipids due to different structures. Phospholipids are much more amphiphilic than triacylglycerols due to. Charged groups at neutral ph: has both hydrophilic and hydrophobic regions. Therefore we can say that phospholipids have: one polar head, two non-polar tails.
