MACROMOLECULES A very large molecule consisting of many smaller structural units linked together.

Carbohydrates What elements can you name in this carbohydrate?

Carbohydrates + = +

Carbohydrates--Functions Primary source of ENERGY

Protein What elements can you name in this carbohydrate?

Proteins + +

Proteins--Functions Some control the rate of reactions and regulate cell processes (called enzymes). Some form bones, muscles, skin, and ligaments. Others transport substances into/out of cells Some help to fight disease.

Lipid (Fat) What elements can you name in this lipid?

Lipid (Fat)

Lipids--Functions Store energy Provide insulation Important parts of cell membranes Waterproof coverings (waxes, ex: bird feathers)

Nucleic Acid What elements can you name in this nucleic acid?

Nucleic Acids Nucleic acid nucleotide

Deoxyribonucleic Acid (DNA) 14 Double helix (spiral) Stores genetic information

Ribonucleic Acid (RNA) 15 – single helix – Plays a role in manufacture of proteins – Enzyme (speed up reactions)
