Protein Structure Flashcards
Explain the primary structure
The sequence of amino acids in the polypeptide chain
How are amino acids linked together?
Peptide bonds
Describe the secondary structure
Describes how the protein is coiled; formed as a result of the hydrogen bonds b/t the carboxyl and amine groups of close amino acid monomers
What are the 2 types of secondary structures?
Alpha-helix and beta-sheets
Tertiary structure
3D structure of protein; formed as result of bonds between side chains of amino acids (R groups)
The bending and twisting of the tertiary structure is done to achieve…
either maximum stability or lowest energy state
Quaternary structure
Proteins consisting of multiple polypeptide chains; referred to protein subunits
