Biological Molecules

The Molecules of Life


Part 1: Background, Carbohydrates, & Lipids

Questions to answer:

  1. How are macromolecule polymers assembled from monomers?  How are they broken down?
  2. How can you tell a biological molecule is a carbohydrate?
  3. Explain the relationship between monosaccharides, disaccharides, and polysaccharides.
  4. Why are starch and glycogen useful as energy storage molecules, while cellulose is useful for structure and support?  Why isn’t cellulose easily broken down?
  5. How do herbivores solve the problem of cellulose digestion?
  6. How can you tell a biological molecule is a lipid?
  7. Chemically, what is the difference between a saturated fat and an unsaturated fat?  How does this difference affect the properties of the molecules?
  8. How are triglycerides, phospholipids, and steroids similar?  How do they differ?

(feel free to ask questions about them in class)


Part 2:  Proteins & Nucleic Acids

Questions to answer:

  1. Why are proteins the most complex biological molecules?
  2. Draw the structure of a general amino acid.  Label the carboxyl group, the amino group, and the variable (‘R’) group.
  3. Draw the formation of a peptide bond between two amino acids.
  4. How does the structure of the ‘R’ group affect the properties of a particular amino acid?
  5. Define each of the following levels of protein structure and explain the bonds that contribute to them:
  1. Primary
  2. Secondary
  3. Tertiary
  4. Quaternary
  1. How can the structure of a protein be changed (“denatured”)?
  2. Draw a nucleotide.  Label the phosphate, sugar, and nitrogenous base.
  3. Explain the three major structural differences between RNA and DNA.
