Function: energy storage

C,H,O – but H to O ratio high *Higher proportion of C-H bonds than carbs. Thus, store more energy per unit of mass

Nonpolar – Thus, insoluble in H2O

Fats - Triglycerides

Glycerol + 3 Fatty acids

-3 carbon alcohol -long chains

-backbone of fat -carboxyl

-saturated or

unsaturated
