Protein Structure Flashcards
(32 cards)
What are the key properties of proteins?
What is the genral formula for amino acid structure
What are the 4 main categories for amino acid classifications?
What are non-polar v polar side chains?
polar interact better with water
what is the difference between acidic and basic side chains?
What are the steps of polypeptide chain synthesis?
What is peptide bond formation?
What happens in chain formation?
What are the 4 levels of protein structure?
Provide an overview of the primary structure.
Provide an overview of the secondary structure.
Provide an overview of alpha-helix sheet structure.
Provide an overview of beta-sheet structure.
Compare parallel and ant antiparallel beta sheet structures
parallell - chained lines up in the same polarity, requires looping
antiperallel - run in opposite directions
Provide an overview of tertiary structure.
What weak forced stabilise tertiary structures?
What strong forces stabilise tertiary structures?
Give an overview of quaternary protein structure.
What are fibrous protein structures?
What are globular protein structures?
What forces contribute to protein folding and stability?
What is the hydrophobic effect?
What is amino acid hydropathy?
high values = non-polar (on interior)
low = more likely to be polar (on the exterior)
What is ubiquitin?
tags other structures for destruction.
