Document Summary

Be able to recognize structures of all macromolecules and their subunits/monomers. Understand how the carbons of a monosaccharide are numbered. Carbon closest to functional group has lowest number. Amylose is a glucose polymer with long chain-like molecules, while amylopectin consists of larger highly branched molecules (1 to 6). Glycogen consists of even more branches than amylopectin. Amylose and amylopectin are classified as starch, and are found in plants, while glycogen serves as the main energy reserve for animals. Chitin makes up the exoskeleton in insects and crustaceans. All lipids are hydrophobic composed of mostly c and h. Phospholipids have 2 fatty acid tails that make bilayers. Fats have 3 fatty acid tails bound to glycerol. Fats consist of fatty acid tails and glycerol linked through dehydration. Saturated fatty acids have only single bonds and are saturated with carbons, allowing them to be solid at room temp. Unsaturated has one or more double bonds, liquid at room temp.
