Chapter 26, Problem 26.14EP

(a)

Interpretation Introduction

Interpretation: To identify whether the statement “the pool is a mix of all 20 standard amino acids” relating to the body’s amino acid pool is true or false.

Concept introduction: The total free amount of amino acid available for use in the body constitutes the amino acid pool. Dietary protein is one of the sources of the contribution of free amino acid to the amino acid pool. Dietary proteins upon complete degradation result in the formation of free amino acid which then enters into the amino acid pool. Amino acids present in the amino acid pool are used in 4 different ways in varying percentage.

(b)

Interpretation Introduction

Interpretation: To identify whether the statement “the main use for the pool’s amino acids is protein synthesis” relating to the body’s amino acid pool is true or false.

Concept introduction: The total free amount of amino acid available for use in the body constitutes the amino acid pool. Dietary protein is one of the sources of the contribution of free amino acid to the amino acid pool. Dietary proteins upon complete degradation result in the formation of free amino acid which then enters into the amino acid pool. Amino acids present in the amino acid pool are used in 4 different ways in varying percentage.

(c)

Interpretation Introduction

Interpretation: To identify whether the statement “dietary protein is the sole source of amino acids for the pool” relating to the body’s amino acid pool is true or false.

Concept introduction: The total free amount of amino acid available for use in the body constitutes the amino acid pool. Dietary protein is one of the sources of the contribution of free amino acid to the amino acid pool. Dietary proteins upon complete degradation result in the formation of free amino acid which then enters into the amino acid pool. Amino acids present in the amino acid pool are used in 4 different ways in varying percentage.

(d)

Interpretation Introduction

Interpretation: To identify whether the statement “only essential amino acids can be withdrawn from the pool” relating to the body’s amino acid pool is true or false.

Concept introduction: The total free amount of amino acid available for use in the body constitutes the amino acid pool. Dietary protein is one of the sources of the contribution of free amino acid to the amino acid pool. Dietary proteins upon complete degradation result in the formation of free amino acid which then enters into the amino acid pool. Amino acids present in the amino acid pool are used in 4 different ways in varying percentage.
