Amino Acids and Proteins Flashcard

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.

Front

What type of bond stabilizes the secondary structure of proteins?

Back

Hydrogen bonds stabilize the secondary structure of proteins, which includes alpha helices and beta sheets.

Front

What is the tertiary structure of a protein?

Back

The tertiary structure of a protein is the three-dimensional shape formed by the folding of a polypeptide chain, determined by interactions among side chains.

Front

What is the quaternary structure of a protein?

Back

The quaternary structure of a protein involves the association of multiple polypeptide chains to form a functional protein complex.

Front

What is the role of amino acids in protein synthesis?

Back

Amino acids are the building blocks of proteins, and they are linked together in a specific sequence to form polypeptides during protein synthesis.

Front

What is the significance of the osmolal gap in clinical diagnostics?

Back

The osmolal gap is used to identify the presence of unmeasured osmoles in the serum, which can indicate certain medical conditions.

Front

What is the normal range for the osmolal gap?

Back

The normal osmolal gap is less than 15 mOsm/kg.

Front

Why is anaerobic collection important for blood gas analysis?

Back

Anaerobic collection is important for blood gas analysis to prevent changes in gas levels due to exposure to air, which can alter results.

Front

What is the Henderson-Hasselbalch equation used for?

Back

The Henderson-Hasselbalch equation is used to calculate the pH of a buffer solution and to understand the relationship between pH, bicarbonate (HCO3-), and carbon dioxide (PCO2).

Front

What is the normal ratio of HCO3- to PCO2 in the Henderson-Hasselbalch equation?

Back

The normal ratio of HCO3- to PCO2 in the Henderson-Hasselbalch equation is 20:1.
