Understand the chemical nature of the peptide bond, how it is formed during condensation of amino acids to form the protein polymer, and the significance of the peptide bond in protein structure. Nucleic Acids Know the different types of nucleic acids Be able to identify the different parts of a nucleotide monomer from a structure diagram or a three- dimensional structure model. Know the difference between a pyrimidine and purine nucleotide base. Know how the nucleotide building blocks are linked together to form a nucleic acid polymer. If you are given the nucleotide sequence of one strand of a DNA molecule, be able to deduce the sequence of the complementary strand.
Carbohydrates Know the difference between a triose, pentose and hexose.
Know the difference between a ketose and an aldose. Know the difference between a monosaccharide, disaccharide and a polysaccharide. Understand the functions of starch, cellulose and glycogen and the types of organisms that produce each type of polysaccharide. Lipids Be able to distinguish whether a molecule is a fatty acid, a triacylglycerol, a phospholipid or a steroid based on a structure diagram or a three-dimensional structure model. Know the difference between a saturated and an unsaturated fat and the significance for the chemical properties and distribution between the plant and animal kingdoms.
