Document Summary
Triaglycerols are fat energy that"s stored in adipose tissue: triacylglycerols include 3 fatty acids + 1 glycerol molecule. Fats- form of reserve fuel storage because when metabolized, they yield more than 2x as much energy per gram as carbs do. A fatty acid consists of a carboxyl group attached to a long carbon skeleton. In a saturated fat molecule all three hydrocarbon tails are saturated (contain all single bonds). You can use any three saturated fatty acid residues in your structure. Glycerol is a 3-carbon alcohol with a hydroxyl group attached to each carbon. Condensation reactions: monoacylglycerol >> diacylglycerol >> triacylglycerol. Fatty acids- look at table 11. 1 in book to read about common fatty acids. Adipose tissue (adipocyte): major site of accumulation of triacylglycerols: a gram of nearly anhydrous fat stores more than 6x as much energy as a gram of hydrated glycogen. Lipids are very critical of the formation of cell membranes. Phosphoglyceride: fatty acids, glycerol, phosphate, alcohol.
