Guided Notes 4
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)
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

Indicator tests are used to test unknown substances for the
presence of organic macromolecules (proteins, lipids, starch, and
the monomer glucose).
Slide 41
When added, Biurets solution turns purple in the presence of
protein.
Slide 42
Brown paper turns translucent (light passes through) in the
presence of lipids
Slide 43
Iodine turns dark blue- black in the presence of starch.
Slide 44
Benedicts solution plus heat turns orange in presence of simple
sugars
