1. The good and bad sides of using triacylglycerols as an energy storage Highly reduced, more than twice as much energy as carbohydrates or proteins(38 kJ/g vs18 kJ/g) Highly hydrophobic: does not raise osmolarity of cytosol, nor add extra weight; but must be emulsified before digestion and transported by special proteins in blood Chemically inert: no undesired chemical reactions with other constituents, but must be activated(by attaching the carboxyl group to coenzyme a)to break the stable c-c bonds1. The good and bad sides of using triacylglycerols as an energy storage • Highly reduced, more than twice as much energy as carbohydrates or proteins (~38 kJ/g vs ~18 kJ/g). • Highly hydrophobic: does not raise osmolarity of cytosol, nor add extra weight; but must be emulsified before digestion and transported by special proteins in blood. • Chemically inert: no undesired chemical reactions with other constituents; but must be activated (by attaching the carboxyl group to coenzyme A) to break the stable C-C bonds
