Carbohydrates and lipids are both organic macromolecules composed of carbon, hydrogen and oxygen. Carbohydrates, such as starch and glycogen, are used for energy storage and structure in plants and animals. Lipids, including fats and oils, provide dense energy storage and make up cell membranes. Both molecule types are insoluble in water and made of long chains of monomers like glucose or fatty acids.

1. Carbohydrates and Lipids Honors Biology

5. Carbohydrate Formula: C 6 H 12 O 6 Notice the ratio of 1:2:1 for carbon, hydrogen and oxygen atoms.

6. Notice the ratio of 1:2:1? For every one carbon there are two hydrogens and one oxygen! C 2 H 4 O 2 C 3 H 4 O 5 C 3 H 6 O 3 CH 4 O 2 C 6 H 12 O 6 C 36 H 72 O 36 C 2 H 4 O 2 C 3 H 6 O 3 C 6 H 12 O 6 C 36 H 72 O 36

11. Sucrose Glucose Fructose + “ two sugars” Sugar Monosaccharides

14. Starch Energy storage in plants! Grains

15. Glycogen Energy storage in you! Carbs stored in muscles

17. Structure in plant cell walls! Cellulose
