Be sure that you can draw an atom if given the atomic number! Water: Diagrams H 20 Bonding is hydrogen 2 hydrogen atoms to 1 Oxygens Behavior freezing 0 degrees C and boiling point 100 degrees C Importance for life on earth. Macromolecules are lipids, proteins, and nucleic acid. Carbs: structure and functions Carbs are energy. Carbo loading is done by runners. Diets Low carb fruits and veggies.

Unhealthy sweetener found in soft drinks Diabetes body inability to regulate blood sugar, insulin located in pancreas used to help regulate blood sugar their two types of diabetes. Lipids: form and function (saturated fats are at room temperature such as butter and cheese) vs. unsaturated (healthier but they are liquid are room temperature. fatty acids, long term energylong hydrocarbon chain of carbon molecules. Head is made of glycose and the ends is fatty acids. Proteins: Form and function made up amino acids which are building blocks) Example of Carbon Atom 6 Example of Water Molecule
