Amino acid and proteins:  structure - function.

• Basic structure
• R groups
• charge
• hydrophobicity
• size/bulk
• the peptide bond
• levels of protein structure
• primary
• secondary
• alpha helix
• beta sheet
• tertiary
• quaternary
• factors that influence protein structure and function
• primary sequence - mutations
• environmental factors
• temperature
• pH
• ion levels
• biological factors
• interactions with other proteins and biomolecules
• covalent modifications - i.e. phosphorylation.
• relevance of protein structure to cell communication
