Proteins – elements and functions
 monomer and polymer
 Amino acids – 3 parts
 20 kinds – how are they different?
 Peptide bond – where is it?
 Levels of structure
o Primary – amino acid sequence
o Secondary – pleating and coiling; hydrogen bonding
o Tertiary – folding into 3-D shape; interactions between side groups
o Quarternary – two or more polypeptides
 Polypeptide and protein – what is the difference?
 Denature – what is it? How does it happen? What results?
Enzymes – What are they? Why important?
 Activation energy
 Active site and substrate
 Mode of enzyme action – induced fit, lock-and-key
 Factors which affect enzyme action
o Temperature
o pH
o enzyme or substrate concentration
o inhibitors – competitive, non-competitive
o feedback
Nucleic acids – elements and functions
 monomer and polymers
 Nucleotide – 3 parts
 DNA and RNA – how alike?
o How different in structure?
o How different in function?
