Presentation Transcript

  1. Chemistry of Life Chapter 6

  2. Elements • Everything is made of elements • An element is a substance that can’t be broken down into simpler chemical substances • Ex. Carbon, Hydrogen, Oxygen, Nitrogen, Calcium, Fluorine, Lithium, Gold • (Elements are made out of atoms)

  3. Compounds • Elements can bond together to form compounds • A compound is a substance that is composed of two or more different elements that are chemically bond • Examples: • Water is H2O • Salt is NaCl • Glucose (sugar) is C6H12O6

  4. These are all the elements known in existence

  5. Different types of compounds: • All compounds on this Earth are either classified as inorganic or organic. • Inorganic Compounds do not contain carbon elements • Organic Compounds contain carbon elements

  6. Importance of Carbon • Carbon is used to distinguish between all compounds because it is so important to life: it’s the “backbone” of all living things • Carbon has the ability to form many different types of bonds and shapes • Carbon can bond to itself and other elements

  7. Inorganic Compounds • Examples of inorganic compounds include water and salt • Water is the most important inorganic compound to life • We’ve studied the properties of water and its unique characteristics and how that relates to living things • Salt’s chemical formula is NaCl (sodium chloride) so it’s also inorganic

  8. Organic Compounds are divided into 4 major classes: • Carbohydrates • Proteins • Lipids • Nucleic Acids

  9. Major Elements of Human Body • The majority of the human body and most living things is made up of just 4 basic elements: • Carbon (C) • Hydrogen (H) • Oxygen (O) • Nitrogen (N)

  10. Food Sort Activity (Examples of Compounds) Carbohydrates Proteins Lipids Nucleic Acid

  11. Food Sort Activity (Examples of Compounds) Carbohydrates (Sugars) Proteins Lipids (Fats, Waxes, Oils) Nucleic Acid

  12. Food Labels Activity • Your group will be given a food label (from food sort) • Analyze the food label and identify the following: • What organic compounds are in this food? • What inorganic compounds are in this food? • Identify the calorie, fat, sodium, sugar, and protein content.
