4. lipid carbohydrate protein nucleic acid water 1.Water is the most important inorganic compound in living things. 2. Most cellular processes take place in water solutions. 3. Excellent solvent (substances dissolve in water) CO 2

5. 4.Are organic compounds containing carbon, hydrogen, and oxygen in the ratio 1:2:1 (carbon:hydrogen:oxygen) Carbohydrates 3.Are made by plants (autotrophs) 2.Are the body’s primary source of energy 1.Are made of monomers (building blocks) called monosaccharides

6. Glucose is a monosaccharide. C6C6 H 12 O6O6O6O6 Example of Carbohydrate: Monosaccharides (simple sugars) are easily identified by their sweet taste. Other monosaccharides: fructose (fruit sugar) galactose (milk sugar). H CH2OHCH2OH O O H H H H OHOH OHOH OHOH H HH OHOH OHOH C C C C C Note the ring shape of the molecule.

7. Example of Carbohydrate: Polysaccharides are complex carbohydrates made of long chains of monosaccharides. Starches (bread, cereals, and pastas) and cellulose (plant cell walls) are common sources of complex carbs. Sucrose (table sugar) is an example of a sugar with only two monosaccharides.
