What is the relationship between amino acids and proteins?
Proteins are made of one or more folded polypeptide chains of amino acids.
What happens when a protein denatures?
Bonds break → tertiary structure lost → loss of function.
What determines a protein’s shape?
Interactions between R-groups (hydrogen bonds, ionic bonds, disulfide bridges, hydrophobic interactions).
Give an example of a quaternary protein.
Insulin (2 polypeptide chains joined by disulfide bridges).
Why do channel proteins have polar and non-polar regions?
Non-polar R-groups face membrane; polar R-groups line the channel for molecule passage.
