15. Discuss a couple of the interactions that can occur between the R groups of an amino acid sequence.

(Students could choose to discuss electrostatic interations (i.e., ionic bonds), hydrophobic interactions,

disulfide bridges, or H-bonds.)

16. a) Some parts of amino acids are common to all amino acids while other parts are unique. Explain (All

amino acids have an amino group and an acid group but each differs in its unique R group. They are all

similar so they can bond together but different so they interact differently in different environments.)

b) How does having different R groups make amino acids ideal building blocks for proteins?

(Different R

groups behave differently in different environments and form different interactions. This allows a protein to

function in a particular environment.)

17. a) Which elements are found in proteins but in neither carbohydrates nor lipids. (Nitrogen and sulfur.)

b) Which element is found in nucleic acids but in neither carbohydrates nor proteins?

(Phosphorus.)

18. Name the basic building blocks for each of the following molecules:

a) Protein

_____ (Amino acids.)

(b) Triglyceride

_____ (Glycerol and 3 fatty acids.)

(c)

Carbohydrate _____ (Monosaccharides.)

(d) Nucleic acids _____ (Nucleotides.)

19. Proteins are to amino acids as polysaccharides are to

. (Monosaccharides.)

20. a) You connect a molecule of ribose, a phosphate, and a molecule of cytosine. What have you made?

(You have made a RNA nucleotide.)

b) Why can you not say you=ve made a nucleic acid?

(A nucleic acid is a polymer of nucleotides.)
