Organic – featuring carbon as the key structural element of the molecule c. Assembled as Polymers which are large molecules built by linking many smaller molecules together. These act as subunits of the macromolecule. i. Molecules that act as subunits are called Monomers d. Four classes of Biomolecules i. Carbohydrates ii. Lipids (Fats) iii. Protein iv. Nucleic Acid e. Synthesized by means of Polymerization i. Condensation Rxn – a reaction during which monomers are linked. Making an H2O molecule per rxn. More specifically – Dehydration Rxn Diagram on page 63 f. Broken down by Hydrolysis i. A rxn where covalent bonds between monomers are broken by adding H2O molecules – reverse of Dehydration II. Carbohydrates a. Monomer – Monosaccharides (Simple Sugar) b. Classified based on a number of simple sugar molecules i. Monosaccharide – single sugar molecule
