STUDENT LEARNING OBJECTIVES Students will explain how carbon is uniquely suited to form biological macromolecules (ref. BIO.A.2.2.1). Students will compare the structure and function of carbohydrates, lipids, proteins, and nucleic acids in organisms (ref. BIO.A.2.2.3). Students will describe how biological macromolecules form from monomers (ref. BIO.A.2.2.2).

MACROMOLECULES Very large molecules ( polymers ), made up of smaller organic molecules called monomers. (*MONOPOLY – one person owning all properties!) Made up of: nitrogen (only in proteins), oxygen, hydrogen, and carbon. BREAK IT DOWN! Macro - large Mono – one Poly - many

WHAT ARE THE 4 MACROMOLECULES? 1.Carbohydrates 2.Proteins 3.Lipids 4.Nucleic Acids

CARBON So unique! Can bond to itself and other elements to make many different types of compounds.

CARBOHYDRATES Act as quick energy source within bodies of living organisms. Monosaccharides as their monomers. Examples of monosaccharides: glucose, fructose, galactose BREAK IT DOWN! Mono – one Sacchar - sugar

PROTEINS In animals, used in muscle-building and growth. In plants, act as an essential part of their structure. Enzymes are proteins. Amino acids are the monomers of proteins. Only macromolecule that contains Nitrogen.

LIPIDS Lipids are used as stored energy. Fats and oils Lipids’ base units aren’t considered monomers. Building blocks of lipids are: Glycerol + 3 fatty acids = triglyceride (lipid)

NUCLEIC ACIDS DNA and RNA Made up of: 1.sugar 2.phosphate 3. nitrogenous base. (Adenine, Cytosine, Guanine, Thymine) The order of the nitrogenous bases determines the information. Proteins are made from the sequences of the bases.

HOW ARE POLYMERS FORMED? Dehydration synthesis reaction: monomer + monomer  polymer + water

REVIEW (FROM THE BIO KEYSTONE PRACTICE TEST)

COLLABORATIVE ACTIVITY Nucleic Acids Carbohydrates Lipids Proteins -Place each characteristic card under the correct macromolecule. -Compare with other groups when finished.
