Monomer & Polymer Notes 10/2014
2
Monomer vs. Polymer Basic Unit Chain of Units Basic building blocks Large molecule or chain of basic structures Monosaccharide (Sugar)Polysaccharide (Starch)
3
Monomer vs. Polymer Basic Unit Chain of Units Basic building blocks Large molecule or chain of basic structures Monosaccharide (Sugar)Polysaccharide (Starch)
4
Four Major Compounds in all Living Systems Sugars - carbohydrates, cellulose & starch Lipids - Plant and Animal fat such as olive oil & lard Amino acids - proteins such as in milk and eggs Nucleotides - nucleic acids; heredity
5
Monomer: glucose, fructose, monosaccharides Polymers: Starch, carbohydrates Monosaccharid e (Sugar) Polysaccharide (Starch) Sugars (carbohydrates): Instant Energy
6
Lipids (Fats): Long-term Energy Storage One Glycerol Unit = connects everything Fatty acid groups = branch off of glycerol 1 Glycerol + 3 Fatty Acids = Whole Fat (Monomers) (Polymer) (Monomers) (Polymer) http://people.ouc.bc.ca/woodcock/molecule/pic/fat.gif http://members.aol.com/Bio50/LecNotes/LNPics/ln03l.gif
7
Monomer = 20 amino acids are the building blocks of protein Polymer = Protein Humans can produce 10 of the 20 amino acids. The others must be supplied in the food! Unlike fat and starch, the human body does not store excess amino acids for later use—the amino acids must be in the food every day. Amino Acids (Protein): Repair and Build Cells Lysine
8
Nucleotides (Nucleic Acids): Store and Transfer Genetic Information Monomer: Nucleotides (A, C, G, T, U) Polymer: DNA & RNA
