2 OBJECTIVES I You should understand and be able to describe: the four groups of macromolecules and their characteristic features what dehydration and hydrolysis reactions are and their roles in macromolecule chemistry the subunits of each macromolecule the characteristic bonds that hold them together functions of each macromolecule the characteristics of an amino acid the forces involved in protein folding the 4 levels of protein structure the difference between protein denaturation and dissociation

3 OBJECTIVES II structural and chemical differences between DNA RNA the structure of a nucleic acid the different classifications of nitrogenous bases the double-helix structure of DNA the structure of a lipid and the chemical basis for their characteristic behavior in water the difference between saturated , unsaturated and polyunsaturated lipids the difference between a monosaccharide , a disaccharide and a polysaccharide the difference between transport , storage and structural forms of carbohydrates

5 Overview All living things are made up of four classes of large biological molecules: carbohydrates , lipids , proteins , and nucleic acids Within cells, small organic molecules are joined together to form larger molecules Macromolecules are large molecules composed of thousands of covalently connected atoms Molecular structure and function are inseparable

6 Biological Molecules A polymer = long molecule consisting of many similar building blocks Small building-block molecules are called monomers Three of the four classes of life’s organic molecules are polymers: Carbohydrates Proteins Nucleic acids 4th class = lipids

7 Polymers are long molecules built by linking together small, similar subunits Dehydration synthesis removes -OH and -H during synthesis of a new molecule Also called condensation reactions Enzymes are macromolecules that speed up the dehydration process Hydrolysis breaks a covalent bond by adding -OH and -H
