Front

What is the term for the end of a protein with an amino group?

Back

N - terminus

Front

Where do negatively charged R groups typically orient themselves in a protein structure?

Back

Exterior of protein due to negative charge providing hydrophilic properties

Front

Which protein structure involves interactions between R groups in a single polypeptide?

Back

Tertiary structure

Front

What type of bond is primarily found in the secondary structure of proteins?

Back

Hydrogen bond

Front

What is the primary structure of a protein?

Back

The sequence of amino acids in a polypeptide chain.

Front

What is the secondary structure of a protein?

Back

The local folding of the polypeptide chain into alpha-helices and beta-sheets.

Front

What interactions stabilize the tertiary structure of proteins?

Back

Hydrophobic interactions, hydrogen bonds, ionic bonds, and disulfide bridges.

Front

What is the quaternary structure of a protein?

Back

The arrangement of multiple polypeptide chains into a single functional unit.

Front

What role do R groups play in protein folding?

Back

R groups determine the interactions and stability of the protein structure.
