Proteins Flashcards
proteins are polymers of
amino acids
numbering system
n-terminus to c-terminus
secondary structures of proteins
alpha helix
beta pleated sheet
coiled coil
two alpha helices wrap around each other
what determines secondary structure
peptide backbone hydrogen bonds
what determines tertiary structure
side chain interactions
an example of a tetramer
hemoglobin
how does a protein denature
high temperature
how does a protein renature
lower the temperature
what is protein turnover
breakdown and resynthesis of a protein
protein breaks down into separate amino acids, new protein is made
why does a protein need to turnover
because proteins denature over time and stops functioning properly
chaperone
specialized protein that help keep other proteins from interacting inappropriately with one another
