1. Molecules of Life

2. Carbon Compounds

3. The Versatile Carbon Atom Carbon has 4 electrons in outer shell Can form a bond with four other molecules

6. Molecular Structure What is a polymer? Monomer? How are they assembled?

7. Monosaccharaides are single-unit sugars These molecules typically have a formula that is a multiple of CH 2 O Each molecule contains hydroxyl groups and a carbonyl group Monosaccharaides are the fuels for cellular work Carbohydrates Figure 3.4A

8. Isomers Glucose and fructose are isomers They contain the same atoms but in different arrangements

9. The ‘Ring’ form

10. Polysaccharides

11. Lipids Not true polymers Hydrocarbons that are non-polar Triglycerides are our bodies main energy reserve

13. Phospholipid

14. Lipids Steroids like cholesterol make up parts of cell membranes Steroid hormones

15. Form & Function

16. Proteins Used for structural components (cartilage)and functional (enzymes) Amino acids: carboxyl, amine and R-group

20. Primary Structure of a Protein

22. How Are Proteins Made?

23. Nucleic Acids Genetic material Link between gene & proteins Energy carriers and chemical messengers Nucleotides: sugar, phosphate, nitrogenous base ATP
