1. Organic Chemistry Objective:
1) Identify the different types of organic compounds, their structure & functions

2. Biomolecules Also called organic molecules
Living cells are made of biomolecules
Large, complex molecules (polymers)
Built from smaller, repeating parts (monomers)

3. Carbon is the basis for Biomolecules
Forms four stable covalent bonds
Diversity of shapes: rings, chains, branches

4. Types of Biomolecules:

5. Carbohydrates Sugars, starches, and fiber Contain C, H, and O
Function: Supply energy for the body, support for the body, cell recognition

6. Molecular Structure of Carbohydrates
Monomer: Monosaccharides
Polymers: Disaccharides and Polysaccharides
Typically composed of ring structures that can be joined to form more complex carbs

7. Lipids Fats, Oils, Waxes, Steroids Also contain C, H, & O
Functions: long term energy storage, insulation, and to act as a water barrier

8. Molecular Structure of Lipids
Monomer: glycerol (C2H8O3) and fatty acid tails (Carboxyl group + varying hydrocarbon chains)
Polymers:
Saturated Fats: contain maximum number of hydrogens
Unsaturated Fats: contain double bonds

9. Proteins
Function: “Workhorse” of the cell that provides structure and function for the body
Shape of protein determines its function
Contain C, H, N, O + other atoms

10. Molecular Structure of Proteins
Monomer: amino acids
Made up of a carboxyl group (-COOH), an amino group (-NH2), and a variable R group that determines its function
Polymer: Polypeptides which will combine to form proteins

11. Nucleic Acids DNA and RNA Monomer: Nucleotides Functions:
Carry genetic information
