Ch. 2-3 Page in your book
2
Macromolecules “Giant molecules” Four types of organic macromolecules
-Carbohydrates -Lipids (fats) -Proteins -Nucleic acids Monomers – small single unit that builds polymers Polymers- many of the small units built together for a large molecule
3
Carbohydrates Made of carbon, hydrogen, and oxygen in a 1:2:1 ratio
Functions: -Main source of energy for living things -Structural purposes in plants Examples: simples sugars- glucose, complex carbs- starch
4
Carbohydrate Structure
Glucose- C6H12O6- (Monomer) Starch- (Polymer)
5
Lipids Contain carbon, hydrogen, and oxygen (mostly hydrogen and carbon) Functions: -Store energy (more energy than carbs) -Cell membranes - Insulation (keep warm) Examples: fats, oils, waxes Many are made of a glycerol and a fatty acid (No monomer/polymer)
6
Lipid Structure Glycerol and 3 Fatty Acids
No monomer- just one structure
7
Proteins Contain carbon, hydrogen, oxygen, and nitrogen
Made of a chain of amino acids (monomer) Functions: -Control the rate of reactions (enzymes) -Regulate cell processes -Form bones and muscle -Transport substances in and out of cell -Help fight disease
8
Protein Structure Monomer- Amino Acid Polymer- Polypeptide Chain
9
Nucleic Acids Contain carbon, hydrogen, oxygen, nitrogen, and phosphorus Made of nucleotides Functions: -Store and pass on genetic information Examples: DNA, RNA
10
Nucleic Acid Structure
Nucleotide- 5 carbon sugar, phosphate group, nitrogen base- monomer Polymer- DNA/RNA
