Text: Draw an arbitrary peptide. Part 1. Choose 4 letters of the amino acid alphabet from your personal name (first or last) and write the letters out as a peptide sequence. Letters to use: JULI Part 2. Draw the chemical structure of that peptide sequence as it would look in water at pH 7. In the example of PHIL, I would need to join the amino acids Pro, His, Ile and Leu in a structure that shows each covalent bond of the backbone and each covalent bond of the side chains. You need to show the correct electrical charges on the structure. You are not required to show the correct stereochemistry of the chiral carbons. Part 3. Mark up the structure as follows: a) Name the N- and C-termini of the peptide. b) Draw a bold arrow pointing to each peptide bond. c) Draw one (1) water molecule in a hydrogen bond with some part of the peptide. The water molecule you draw can either be an H-bond donor or an H-bond acceptor. Be sure to only draw one water molecule.

Draw your own biological molecules (6 pts) On a blank piece of paper, draw the following: 1. A short peptide (3 pts) - The peptide needs to be three different amino acids long. They can be any three amino acids you like! - Label the following: R groups, backbone, peptide bonds, and the amino acid names (draw a box or bracket around each individual amino acid). 2. A carbohydrate (2 pts) - Label the following: the name of your carbohydrate, whether it is simple or complex, and draw a box or bracket around one of the monomers. 3. A triglyceride (2 pts) - Label the following: glycerol, each fatty acid chain, and whether each fatty acid chain is saturated or unsaturated. 4. A short nucleic acid (3 pts) - The macromolecule needs to be single-stranded and three different nucleic acids long. - Label the following: The type of nucleic acid (DNA or RNA), sugar-phosphate backbone, bases, phosphodiester bonds, and the complementary base for each nucleic acid.
