Organic Compounds & Energy Transformations

Chemical Formulas Example: C6H8O6 (Vitamin C) C, H, O = symbol for element, C = Carbon, H = Hydrogen, O = Oxygen (Capital letter or capital & lower case letter) 6, 8, 6 = Number of atoms of the element (C = 6, H = 8, O = 6)

Organic Compounds Must contain the element carbon (Symbol = C) Example = Cholesterol C27H46O

Organic Compounds Carbon is found in pencil lead, diamonds, graphite, coal, etc.

Organic Compounds Can also contain Hydrogen (H), Oxygen (O), Nitrogen (N), Sulfur (S), Phosphorous (P), etc. Example = Acetaminophen C8H9NO2 P

Inorganic Compounds Do not contain Carbon (C) Example = Rust Fe2O3 Only has Fe (Iron) & O (Oxygen)

Organic or Inorganic? Caffeine C8H10N4O2 Stomach Acid HCl Aspirin C9H8O4 Drano NaOH Salt NaCl Sugar C12H22O11

Energy Transformations Chemical energy in the body is changed into: heat energy, kinetic or mechanical energy, electrical energy, & sound energy.

Proteins, Fats, & Carbohydrates These are the Nutrients our body needs to stay healthy All are organic compounds Carbohydrates and fats give energy Body uses Protein to make new tissues like skin and muscles.

Energy Transformations What energy transformations happen in a flashlight? Chemical to __________ and ___________ energy.
