- Slide 6
- Carbon has four valence electrons, which means it can form four
bonds It can even bond with itself This allows carbon to form long
chains to form bigger compounds
- Slide 7
- Carbon is a very flexible element-it can even form rings Carbon
can form small molecules- called monomers- and these monomers join
together to form larger molecules called polymers
- Slide 8
- Slide 9
- There are four groups of organic molecules: 1. Carbohydrates 2.
Lipids 3. Proteins 4. Nucleic Acids
- Slide 10
- Make up: carbon, hydrogen, and oxygen (C,H, O) Use: structure
and energy Examples: starches, cellulose, glycogen, and
sugars-glucose, fructose, galactose Simple sugars-monosaccharides
Complex sugars-polysaccharides Storing glucose in the body Animals-
glycogen Plants- cellulose (cell wall)
- Slide 11
- Carbohydrates = sugar Glucose Fructose Sucrose -OSE = SUGAR =
CARB
- Slide 12
- Make up: Carbon and Hydrogen (C, H) Uses: store energy, part of
membranes water proof covering Important: Lipids are not soluble in
water. They are also made up of a glycerol and three fatty acids
Examples: fats, oils, and waxes
- Slide 13
- Fatty Acid Glycerol Fatty Acid Glycerol
- Slide 14
- Slide 15
- Slide 16
- Make up: nitrogen, carbon, hydrogen, oxygen) (N, C, H, O) Use:
transport substances, form bones and muscles, speed up reactions
Important: Proteins are made up of chains (polymer) of amino acids
(monomers) Example: enzymes & hemoglobin & insulin
- Slide 17
- Amino Acid
- Slide 18
- Slide 19
- Make up: hydrogen, oxygen, nitrogen, carbon, and phosphorus (H,
O, N, C, P) Use: store and transmit genetic information Examples:
DNA/RNA Important: Nucleic acids are polymers made up of
nucleotides (monomers) Nucleotides-5 carbon sugar, phosphate group,
and a nitrogenous base
