B1.2 HL Proteins Flashcard

Front

What determines the properties of assembled polypeptides?

Back

The R-groups of amino acids determine the properties of assembled polypeptides.

Front

Which type of bond is primarily responsible for the secondary structure of proteins?

Back

Hydrogen bonds are primarily responsible for the secondary structure of proteins.

Front

What is the relationship between the form and function of proteins?

Back

The function of a protein depends on its form.

Front

What type of amino acids helps integral proteins to embed in membranes?

Back

Non-polar amino acids help integral proteins to embed in membranes.

Front

In a water-soluble protein, where would you expect to find the hydrophobic amino acids?

Back

Hydrophobic amino acids are expected to be found in the core of the protein.

Front

Define polypeptide.

Back

A polypeptide is a chain of amino acids linked by peptide bonds.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the sequence of amino acids in its polypeptide chain.

Front

What role do disulfide bonds play in protein structure?

Back

Disulfide bonds help stabilize the tertiary structure of proteins.

Front

What is the difference between essential and non-essential amino acids?

Back

Essential amino acids cannot be synthesized by the body and must be obtained from the diet, while non-essential amino acids can be synthesized by the body.

Front

What is the tertiary structure of a protein?

Back

The tertiary structure of a protein is the overall three-dimensional shape formed by the folding of the polypeptide chain.
