Water + Organic Molecules

Water, Carbohydrates, Lipids, Proteins, and Nucleic Acids

water and polarity3
Water and Polarity
  • Hydrogen and oxygen atoms share electrons
    • Covalent bonds
  • Oxygen pulls more on the hydrogen’s electrons
    • Uneven Pulling = Uneven Charges = Polarity
  • Water molecules are attracted to each other due to polarity
    • Hydrogen bonds are broken and formed very easily
properties of water5
Properties of Water
  • Water Dissolves
    • Charged particles are 'pulled' into solution.
  • Cohesion
    • Water sticks together
  • Adhesion
    • Water sticks to other substances – capillary action
  • High Surface Tension
    • Drops of water on a penny
  • Temp Moderation/Density
    • Earth’s oceans and sweating
carbon compounds7
Carbon Compounds
  • Organic compounds are made primarily of carbon atoms.
  • A carbon atom has four electrons in its outermost energy level.
    • Can form four covalent bonds with other elements or with other carbon atoms.
    • Single, double and triple bonds are possible
    • Straight, branched, ring
functional groups
Functional Groups
  • Functional groups are clusters of atoms that influence molecules.

Hydroxyl group Carboxyl group

Amino group Phosphate group

carbon molecules
Carbon Molecules
  • Monomers
    • Single units
  • Polymers
    • Monomers chained together
  • Macromolecules
    • Large polymers
  • Hydrolysis/dehydration synthesis
    • Process of building and breaking down monomers
slide11
ATP
  • Life processes require a constant supply of energy.
  • ATP
    • Adenosine triphosphate
    • Compound stores a large amount of energy
carbohydrates
Carbohydrates
  • Carbohydrates
    • Carbo = Carbon
    • Hydrate = Water
    • Carbohydrates can serve as a source of energy or as structural materials.
    • Carbohydrates are polar due to the large amounts of oxygen.
monosaccharides14
Composed of C : H : O

1: 2 : 1 ratio

Three Most Common Types

Glucose

Fructose

Galactose

Monosaccharides
disaccharides16
Disaccharides
  • Disaccharides
    • Two monosaccharides combined
    • Disaccharides are called a “Double Sugar”
    • Sucrose = Glucose + Fructose
    • Lactose = Glucose + Galactose
polysaccharides18
Polysaccharides
  • Composed of three or more monosaccharides
  • Glycogen
    • Hundreds of glucose chained together
    • Storage of energy, found in liver and muscles
  • Starch
    • Highly branched chains of glucose
  • Cellulose
    • Long, unbranched chains of glucose
    • Thousands of monomers
carbohydrates food20
Carbohydrates & Food
  • There are two types of carbohydrates in food
    • Simple: Monosaccharides and disaccharides
      • Fruit, milk, vegetables
    • Complex: Polysaccharides
      • Breads, rice, pasta, starchy vegetables
