Compare and contrast the functions of carbohydrates and lipids. explain the function that carbohydrates and lipids have in common. next, describe other functions each of these biomolecules have that are unique to their category.

Carbohydrates and lipids have similar function. They both are used for energy but carbohydrates are short-term energy and is used first. After carbohydrates are used, the lipids are next and are the long-term energy.

Functions of carbohydrates:

-short term energy: glucose

-stored energy(plants:starch, animals:glycogen)stored in liver and muscles

-structure: cellulose cell wall &chitin exoskeleton & fungal cell wall

-made of C,H,O

-4kal/g

Monomer: mono-saccharide

Polymer: di- saccharide & poly saccharide

Lipids

-made of 3 fatty acids and 1 glycerol

-no polymer or monomer

-made of C,H,O

-9kal/g

-insoluble in water

Functions of lipids:

-storage of energy(long term:triglycerides)

-hormones ( estrogen & testosterone)

-insulation(thermal: triglycerides)

-protection (internal organs of animals) (waxes in plants)

-structure (cell membrane: phospholipids)

-E shaped
