1 Molecules of Living Systems

2 Objectives

3 Macromolecules – 4 types
Carbohydrate Lipids Proteins Nucleic Acids

4 Why do we need Macromolecules?
Royal

5 Assembling and Diassembling Macromolecules
Dehydration Synthesis Enzymes Covalent Bond Hydrolysis

6 Carbohydrates Simple sugar Polysaccharide 3-7 C Monosaccharide
Disaccharide Polysaccharide Starch Glycogen Cellulose

7 Dehydration and Hydrolysis of Carbohydrates

8 Lipids Energy source Phospholipids – Cell structure Saturated
Unsaturated

9 Dehydration and Hydrolysis of Lipids

10 Protein Subunit is amino acid

11 Dehydration and Hydrolysis of Proteins
Amino acids are connected by peptide bonds Bonded amino acids are polypeptides How they bond determines their 3D shape as well as the type of R group

12 Nucleic Acids RNA – ribonucleic acid (mRNA – messenger RNA)
DNA – deoxyribonucleic acid

13 Distribution of Body Fluids
Larger more complex assemblies of organic molecules found in Compartments are called Macromolecules.

14 Gangnam Style
