  2. UNIT 1: ORGANIC COMPOUNDS P. 37(TEXTBOOK) CARBOHYDRATES LIPIDS PROTEINS

  3. What is a ORGANIC MOLECULE?

  4. PROPERTIES OF ORGANIC COMPOUNDS • Always contain carbon and hydrogen • Living organisms • Covalent bonds • Large molecules

  5. BIOLOGICALLY IMPORTANT FUNCTIONAL GROUPS What is a functional group?

  6. BIOL. IMPORTANT FUNCTIONAL GROUPS AND THE COMPOUNDS THEY FORM • HYDROXYL - Alcohol • CARBONYL – Aldehyde and ketones • CARBOXYL – Carboxylic acid • AMINO - Amine • SULFHYDRYL - Thiol • PHOSPHATE – Organic phospates

  7. CARBOHYDRATES

  8. PROPERTIES OF CARBOHYDRATES • C : H : O – 1 : 2 : 1 • MonomeresMonosaccharides (single sugars) – 1 • Disaccharides – (double sugars) - 2 • Polysaccharides – (chains of sugars)-many

  9. Monosaccharides • E.g. Glucose, Fructose and Galactose • What is an Isomers? • Function of monosaccharides?

  10. GLUCOSE • Hexose sugar – 6 C atoms • C6H12O6 • Structure:

  11. PENTOSE SUGARS • 5 C – atoms • E.g. deoxyribose sugar and ribose suger • Part of RNA and DNA
