(a)

Interpretation Introduction

Interpretation:

Given food combinations provide the essential amino acids; lysine, tryptophan and methionine should be verified.

Concept introduction:

Essential amino acids are those amino acids which are very useful but are not produced in the human body. For this reason, we have to intake those amino acids through our diet.

Answer to Problem 19.55UTC

Solution:

Provides those three essential amino acids.

Given: Rice and garbanzo beans

Explanation of Solution

The table 19.1 is as follows:

    SourceLysineTryptophanMethionine
    OatmealNoYesYes
    RiceNoYesYes
    Garbanzo beansYesNoYes
    Lima beansYesNoNo
    CornmealNoNoYes

From the given table we know, rice provides tryptophan and methionine. Garbanzo beans provide lysine and methionine.

Therefore, the food combination; rice and garbanzo beans provide all three amino acids; lysine, tryptophan and methionine.

(b)

Answer to Problem 19.55UTC

Solution:

Provides only lysine and methionine.

Given: Lima beans and cornmeal

Explanation of Solution

The table 19.1 is as follows:

    SourceLysineTryptophanMethionine
    OatmealNoYesYes
    RiceNoYesYes
    Garbanzo beansYesNoYes
    Lima beansYesNoNo
    CornmealNoNoYes

From the given table we know, lima beans provide lysine. Cornmeal provides methionine. Neither lima beans, nor cornmeal provides tryptophan.

Therefore, the food combination; lima beans and cornmeal provide only two amino acids; lysine and methionine.

(c)

    OatmealNoYesYes
    RiceNoYesYes
    Garbanzo beansYesNoYes
    Lima beansYesNoNo
    CornmealNoNoYes

From the given table we know, garbanzo beans provide lysine and methionine. Lima beans provide lysine. Neither garbanzo beans, nor lima beans provide tryptophan.
