ORGANIC MOLECULES

Proteins

PROTEIN • ELEMENTS: C H O N (sometimes P and S) • BUILDING BLOCKS (SUBUNITS): amino acids (20) • FUNCTIONS: 1. 2. 3. 4. 5. 6. 7. growth and repair *enzymes – speed reactions (End in –ASE) Hormones –insulin, controls blood sugar Immune System – antibodies and white blood cells Hemoglobin – carries oxygen in the blood nails, hair, muscle last resort source of energy* • SOURCES: dairy products, peanuts, meat, fish (if it had a mama it is a protein!)

BONDING OF AMINO ACIDS • Amino acids bond together making proteins. • C—N peptide bond forms between amino acids • Amino acids end in: ine or -ate

Nucleic acids

NUCLEIC ACIDS • ELEMENTS: C H O N P • BUILDING BLOCKS: nucleotides • Sugar + phosphate+ N base • FUNCTIONS: 1. genetic blueprints 2. transferring information • EXAMPLES: DNA and RNA

Carbohydrates Proteins Lipids Nucleic Acids

Biomolecule Foldable Front cover: • Name of biomolecule • Basic structural drawing (polymer) Within each section include: • Name of biomolecule again • Name of monomer(s) • Chemical components (what elements? ) • Function within us • Examples • Additional special properties Back: • Your name and class block Things to remember: • Be sure to organize your information in a way that you can use it. • Basic structures for both the monomer and the polymer are needed. • Neatness matters
